Macro Lens: Technique and Choices
We all know that we would like to have a one to one reproduction ratio in the lens but that's only gonna happen in the macro lenses so the macro lenses that cannon has they have one land specifically designed for their crop frame cameras and then they have a collection of them designed for their full frame and they have a couple of interesting ones that we'll need to talk about in here and you'll notice that they have different focal lengths and down here at the bottom we've added in our one times magnification because now we understand what this means point five magnification oh this one's not as good as the others one two five magnification way what's going on there that's kind of interesting we're going to talk more about this one but all the others are at one times magnification the difference on these lenses comes down to their focal inc and that's the next thing that we need to talk about before we actually get into the lenses themselves the focal length is going to determine how...
close to our subject we are when we're taking pictures with the fifty millimeter lands were going to be very very close to our subject with one hundred millimeter lands were going to be further away and that could be advantageous because maybe this isn't a tulip maybe it's a snake and we don't want to be really close to it maybe there's lighting that we have we have a soft box, or we have the sun or a reflector. And we don't want to get in the way of that. And so it's. Many times more convenient to be further away from your subjects. So you're not disturbing the light for disturbing your subject in any way. And what tends to happen is that the maurin more serious of photographer you are, the longer the focal length lens that you'll choose together. And so having a little bit of working spaces nice mostly for light reasons you're not blocking the light source if you're no glean in two inches above your subject you are going to drastically change the light source and so having a slightly longer focal length blends so that you're just a little bit further away from your subjects you don't disturb it you don't actually bump drops of water off is a nice thing to have so that's one consideration and getting the macro lens so this is going to be the sharpest way that you can get close up subjects he's also tend to be very sharp for other purposes as well if you want to shoot him for portrait photography or landscape photography all purpose photography it's very good they tend to be a little bit bulk here and a little bit slower than standard prime lenses for general work but if you're looking for a multipurpose device that is also very good in close up it works very well it's also really nice for portrait work you know for instance if you want to dio wedding photography occasionally you're going to shoot a lot of portrait but you might want to get some ring shots where you might want to do a really tight shot of just the eye and the nose and you could do that with a short telephoto in a macro lens very, very white purpose lens so as far as the technique. A lot of people don't do it right with the macro lenses. What you want to do is you want to set the lens to the desired magnification if you can figure that out ahead of time which means manually focusing as close as you think you need to be I need to photograph ah baseball that would be how big is a baseball about three inches across maybe so I would need to set it one two three so if you're going to send one to two I'm gonna photograph I know something two inches what's like a pair or something something that size so you would set this manually and then you would move the camera for focusing and so you would change magnification by changing the focus and then what you would do is you would move the camera back and forth and so the problem that a lot of people have is that they're using auto focus and they're in on their subject and they focus in on their subject and they don't realize this but they're moving back and forth ever so slightly and so they focus and they lean in two millimeters and it throws all the focus off and so it's better just to set the focus and it's nice that you saw me 00:04:01.043 --> 00:04:02. didn't you see me when I was I'm embracing my hand 00:04:02.98 --> 00:04:05. right here I'm trying to stabilize my movement so 00:04:05.55 --> 00:04:09. I'm not moving as much honestly though that handheld 00:04:09.17 --> 00:04:11. is just not the way you should be doing that you should 00:04:11.1 --> 00:04:13. be doing it on a tripod. That would be a much better 00:04:13.74 --> 00:04:16. technique. And there are special focusing rails to 00:04:16.61 --> 00:04:19. move the camera back and forth if you really get into 00:04:19.05 --> 00:04:20. that type of photography. So for their crop frame cameras they make a good general purpose macro lands sixty which has thie angle of view of a ninety which for macro photography has been a very popular number that short telephoto of ninety makes for a good general purpose if you are using crop frame and you know you're going to stay in the crop frame world this is a great lands to get very, very sharp probably the sharpest f s lands that cannon makes at any focusing distance for the rest of the group there's each one that fits kind of a special unique needs so let's go ahead and run through these lenses pretty quickly so as I said this is the only one that they make for their crop frame sensors I really can't say enough about this this is I think probably the best lens that cannon makes with their f s lenses in mind specifically for it very good general purpose gets up one to one with that crop frame sensor it's not too big good for portrait work so great general purpose lands think it's think the highest of it the e f lenses this lands is eons old it came out in nineteen eighty seven it is long overdue for an upgrade and given the fact that there are some aftermarket lenses that we're going to talk about, I really can't recommend this lens for anyone. I think there's some better options out on the market it's small it's, lightweight. It does a decent job. It is on ly a one to two macro it's, not a one to one macro bit. You'll be able to find someone to one macros in this size and price range. If you're willing to look at some other manufacturers toget to one to one, it just they didn't have the technology back then to do it very well. So it was very common for lenses to go one to two, and then you had to buy a life size converter, which works a little like an extension to. But it does have optical elements, and it is specifically dye designed for this one lens in order for it to get to one to one mac relation. Now this lens is going to cost around three hundred bucks, and this converter is going to cost you about three hundred bucks. And so if you want to get one toe one, just take that six hundred bucks and spend it on an actual macro lens that will get you where you need to go. This is a very unique very special lands this is the sixty five millimeter lands and you cannot focus on infinity on this lands it is designed specifically and on lee for close up work but it will do so at a magnification of one times zooming in doesn't really technically zoom in but by focusing closer it changes the magnification to five times magnification and so if you want to photograph on two letters on a printed page aa bb in size you can do so with the sixty five less and so it is close up work on lee it is extremely close we do have one of these lenses over here and this is the sixty five it comes with thistle tripod collar and it's focused at infinity right now which really is infinity but as we focus up closer and closer and closer I think we did we do this before this fields this is the close up lens and you're focusing about this far away and you can photograph a grain of rice and aunt anything anything really really small like that and so this is for somebody who is very, very into macro photography the downside on this is that you can't shoot standard stuff with it and it'd be nice if you had a little bit more working distance between the front of the lens and the subject and so it's a it's a fairly pricey thing and it's probably not going to get updated anytime soon it's a very specialized item all right this was kind of their older one hundred millimeter lens they replaced it with a new l version we're going to talk about next I own this lens for many years and I always thought this was my sharpest cannon lands that I'd ever had and it is a really, really good lands and it's it's a great value I think of anyone who wants a good standard full frame lands for canada this is just a great value does not come with the tripod mount ring that's an optional thing the lens really isn't that heavy so it doesn't need it on many cameras but I really feel like I want to recommend this to a lot of people who need a reasonably priced well is reasonably priced to some of these lenses are a decent cannon brand macro lands from sf photo man I'm wondering about the reverse mounting of a cheaper lens to make it a macro yeah so one of the interesting things that you could do if you could take a wide angle lens reverse it shoots through a wide angle lens which expands but now you're going to make it contract and you can get a macro out of it the downside to that and the reason I'm not even gonna go into that in this class is that you lose all the electronics all the focusing options and so it becomes very very manual operation and if we were doing a weekend workshop just on macro photography yes, that would be part of the topics but it is a way that people have done that in the past and typically a twenty millimeter lands twenty four eighteen millimeter lens would be the ideal lens that you would want to reverse in that sort of case but it's just it throws so many things off on the camera it's not something that most people want to dio so that's the one hundred and then the new one hundred l has been their new popular kind of main go to macro lens for most people who are into this and so intermediate size I think we had one up here that we're looking at a little bit earlier I don't know exactly what they changed on it and to make it a nail they might have changed some of the lens elements in there but they did upgraded a little bit makes for a very nice portrait lens they did add hybrid image stabilization and I've always thought this is something that you really don't need on a macro lens but I have found out from time to time you do want to shoot things handheld close up and when you're magnified up that close the stabilization system helps out quite a bit and this hybrid stabilization system is fantastic from canada is a really good job with twisting and up and down inside the side movements. And so, if you do need to get handheld shots up close by foreign away. Best lens on the market for doing that. For those who really get into it they want a little bit longer focal length lands and cannons longer focal length is three hundred eighty millimeter lands and this is going to nearly double your working distance you have twice as much room to put lights or stay further away from your subject this is something that is very particular to those who are very into macro photography a problem that I have with this is that there is not much else that you were going to use this lens with one eighty three point five is a little bit slow and a little bit big for a kind of a general purpose telephoto although it will focus on infinity and do a decent job you can use this with extenders so if you wanted to put the one point for extender or the two times extender you can do so on this one and so this is the nice thing about this one is it gives you a forty eight millimeter about a foot and a half working distance so if I'm focusing on something right here going to put the lens back about that far from it and so if you need to stay a little bit further away from your subject for a wide variety of reasons that's their longest and the one eighty two, two hundred range is where the longest of these macro lenses are gonna work. If you needed to get longer than this you could always choose the three or four hundred millimeter lens and add on extension tube's but this is probably your way of getting the actual greatest magnification ratio this question was from design baby who said does the macro setting on a camera matter when it comes to macro lenses or do they even relate so I think talking about maybe like a custom function putting it onto macros there are some cameras that have a macro mode and that does nothing about focusing and you're close of distance and I don't know the idea or how it came about them having the macro mode on there and the design of it because what it appears to be is it simply sets the aperture to an aperture a five point six as if five point six is the perfect aperture for shooting all macro work which it definitely isn't but I guess if you had to choose one number it might be a default number to choose and so those little close up modes on the rebels they're not doing anything with the lands the closeup ability totally depends on the lens that's just playing around a little bit with the exposure and it's not really doing much good anyway thank you one more question in a different segment you talk to us about the difference between zoom and what zoom should be and just how we relate that the lens that you have up there is that a true zoom lens this is not a zoom lens it's a sixty five millimeter lands but it has magda as you cloak focus closer it increases the magnification ratio so when it's all the way back it's at one x and if we get a close up on this you can actually see it's at one x two x three x and so it's just allowing us to focus closer and so if you were in the same spot where you have to reposition yourself for what it's saying yes yes yes and so with this at five x we would probably be about this far away and as we focused down to one x we would have to move a little bit further away I don't know what exact distance would be but yeah he would have to move away highly specialized lens there's really no competitors to that lens on the mark start looking at some of the macro options that you have and we're going to be looking at after market as well as cannon ones this first one is a really unusual one and just because we're going by focal length number this is a fifteen millimeter lands that's a really wide angle lens folks and this is a brand new one that just came out. I have not shot with this or had held it in my hands but it's interesting because it allows you to shoot up very close with a very wide angle lens getting one to one magnification with a fifteen millimeter lands is here. Kitty, kitty, kitty, kitty, kitty. And you're right in kitty's face, and you're going to see the cases, fat eyes and face and everything around it really, really close and it's going to be very unusual. It's. Kind of a bug's eye view, if you would so it's one hundred ten angle of you, it also adds in some tilt shift capability, which we're going to find out more about here in a little bit. And I suppose you could use cannons twenty four one four, because it's a wide angle, and it does focus up pretty close. But it is much, much cheaper. And so, if you wanted something really different in the macro world, that's an option. Sigma makes a number of lenses in here this is a pretty good option for somebody who wanted a fifty millimeter lands and so this one is going to be a comparison to that older fifty that cannon makes so this one gets one to one magnification and the cannon one that we talked about gets one to two now what? And you'll see that we'll actually candidate is quite a bit less than the signal because this one does get one toe one but it allows you to get closer now you might be wondering who buys a fifty millimeter macro versus a one hundred millimeter macro? Is there a benefit to it and there is a benefit to a fifty millimeter macro lens and my camera is gone so I'll just pretend to have my camera here one of the other reasons that you might be using this is to reproduce products or documents let's say you're in charge of taking pictures of documents, paper documents what you might do is you might put him on the floor and then you would photograph him straight down and a great lens to use this with is a macro lens the problem with a hundred millimeter macro lenses if you're trying to photograph ah book or a piece of artwork the camera starts needing to be up here and mounting the camera here focusing and working on it is very challenging and so if you have a fifty millimeter lens you'd be maurine this range with an object that is maybe one foot by one foot. And so for reproduction. Props is time for a little bit larger objects. The fifty is really sharp. It still allows you to get close, so let's say you made pottery or sculptures that were tabletop size, and you wanted a really sharp lands to photograph it and some of the details. Ah, fifty millimeter macro lens would be my first recommendation for that type of use. So's ice makes the macro lens and this is a one to two ratio and because a lot of macro photographers prefer manual focusing having manual focus isn't nearly handicap it was back in the standard prime lenses and so this makes pretty good sense for a macro lens very sharp lens is ice makes some of the great lenses and when you compare it to the cannon I'm going to guess that it's going to blow it out of the water when it comes to image quality it kind of blows it out of the water when it comes to price tag as well but it's also built really really well and the cannon is their first generation of auto focus which which had a lot to be desired in their construction speed and noise of their system cameron has a legendary macro history they have made some of the best they traditionally they have been the best macro company to go to if you wanted if you wanted to lands and so they make a sixty millimeter lands and this is for there a p s c system and so if you have the crop frame sensor that would be a nice lens for that one to one magnification ratio gets you up nice and close about four inches away this is going to compete with 00:18:02.886 --> 00:18:07. the cannon fifty millimeter lands also the cannon 00:18:07.97 --> 00:18:11. sixty one designed for the a p s and it's just a very 00:18:11.74 --> 00:18:13. high quality lands. And I think it's goingto knock 00:18:13.78 --> 00:18:15. the socks off of the canyonlands in this case. Venus optics makes another unusual one and this is the only one on the market that I know of other than this sixty five that will go more than one to one and so if you need more than one to one it is a manual focus on lee it's a very simple design and it is only for the a p s c system and so in this case it's going to use being used for the rebels in the sixty seventy days and so forth and if you want that to tow one well there's really not a lot of competition out there and so it's the same price but it's twice as close definitely some tradeoffs in that one going full frame with tamara this is kind of the classic ninety that they've had out for quite a while they have a very good optics system in here so you can expect a very sharp pictures a lot of people very happy who owned this lands who want to shoot close up probably best comparison is with the older one hundred millimeter lands and it's going to be near to the same price but their reputation says that you're going probably get very good images from that although I was really happy with the nikon so that's a bit of a toss up between those two this is the new version of the ninety cosmetically it's new it's got a nice big focussing ring on it and this is probably kind of the go to standard for a lot of photographers who want something other than the cannon option. And so price wise, it's going to be a fair bit mohr and it's, one of those things you're going to get your hands on to see if it's really worth it for you. But it's something I would look at strongly if you're interested in that focal range for a full frame camera, toki no makes macro lenses as well. This one is one hundred millimeter for their full frame cameras, one to one magnification, so it's quite close. And this one is for somebody who wants to save a little bit of money because it's going to be noticed. Silly, less money, so quite a bit cheaper and a lot cheaper if you were to compare it to say, top of the line. L lens from canon. So sigma makes a number of longer focal length ones. They have a one o five. And all of these are going to be one to one magnification 00:20:26.318 --> 00:20:30. ratios, and so different focal links are going to 00:20:30.03 --> 00:20:32. give us more working distancia. Pierre, we're now 00:20:32.33 --> 00:20:34. up to twelve point, two inches away from our subject. 00:20:34.78 --> 00:20:37. So if you need a bit more working space, you need 00:20:37.76 --> 00:20:39. a longer focal ink that's going to end up costing 00:20:39.71 --> 00:20:42. you a little bit more. Sam, you are buddies over in 00:20:42.86 --> 00:20:46. china, are making this one, and this is manual focus 00:20:46.1 --> 00:20:47. only a lot of the other ones, we've been talking about 00:20:47.97 --> 00:20:51. our auto focus, and this is going to give us very 00:20:51.09 --> 00:20:53. good, close up ability at a very reasonable price. 00:20:54.18 --> 00:20:55. So manual focus only, 00:20:56.71 --> 00:20:58. and I don't know that I have a good reason why it's 00:20:58.52 --> 00:20:59. the same prices, the cannon. 00:21:01.46 --> 00:21:03. But if you like that manual, focus, it's there, 00:21:04.76 --> 00:21:06. back with his ice as we're going up through our focal 00:21:06.99 --> 00:21:08. range. One hundred millimeter. And so this is one to to a lot of those ices are one to two rather than one one but if you really appreciate that manual focusing feel and style of his eyes they do make some very high quality optics in there and they tend to sell for a lot more money a lot of these 00:21:25.838 --> 00:21:29. lenses have what more costs built into the construction 00:21:29.43 --> 00:21:33. of it their hand built in most all cases and very 00:21:33.36 --> 00:21:34. beautiful glass for those needing the longer focal lengths signal's got a one fifty and these lenses air once they're going to be getting bigger very heavily very specialized lenses and I guess the best comparison is thie cannon one eighty and it's going to be a little bit less than that and that's mostly because it's just a little bit shorter in focal length and then we're at the longest focal length kind of the end of the road here one hundred eighty millimeters this lands has something that's kind of unusual about it and that is it has a secondary focussing ring up in front so that you could turn filters mohr easily so that once you attach filters ah lot of times there's lights and hoods and things attached to the front of the lens and so now you can just simply grab this and turning filters and the most likely filter that you would want to be turning is thie polarizing filter people use polarizing filters when they are shooting close up to control the reflections. And this gives you an added element of control. If you're using a set you in a situation like that. And it does sell for noticeably less than the candid camera or the cannon lens. Sigma makes a one eighty as well this is a fairly new style blends from them so it's got a lot of their new focusing systems built into it nice ergonomics on it and so once again this is that longer focal length for getting further away from your subject so here you're now eighteen inches about a foot and a half away from your subject and comparing the price it's actually more money than the cannon and the cannon is an older design and is kind of working off of old rian rnd that has been paid for and at some point we'll see an upgrade to the cannon one eighty and that will probably double that whole lens in price so that is the macro lens let's see if we got to me specific questions that I can answer on that absolutely john let's see that question from ese for territory said how about adding on an extension tube on a macro lens you talk a little bit about that again yeah that's one of the neat things about extension tube's you can adam onto any lends you want and so by all means if one to one is not close enough you can have an extension tube onto your one to one macro lens and now you're going to get closer how close? Well, I don't know it depends on how big that extension to busan. What that lenses all right. So just to summarize macro lenses tell us again what is the difference between the normal 00:24:04.008 --> 00:24:07. one hundred millimeter lens and the macro one hundred 00:24:07.67 --> 00:24:10. millimeter lens not brolin's simply means it can focus 00:24:10.72 --> 00:24:14. really close and traditionally with the normal photographic 00:24:14.64 --> 00:24:17. terminology macro lens means one toe one in some cases 00:24:17.86 --> 00:24:21. one to two reproduction ratio half life sized the 00:24:21.47 --> 00:24:24. object you photograph would be half life size or actual 00:24:24.53 --> 00:24:28. life size on the sensor itself thank you and emily's 00:24:28.31 --> 00:24:31. got a question how about a beginner macro lens you 00:24:31.67 --> 00:24:34. deciding to get let's say I'm going to get into macro 00:24:34.43 --> 00:24:37. don't know what I like or don't like so I want something 00:24:37.26 --> 00:24:40. just to begin with well I would probably start with 00:24:40.15 --> 00:24:42. the extension tube's because you can always add the 00:24:42.67 --> 00:24:45. extension tube's to everything you use so even if 00:24:45.48 --> 00:24:47. you get the extension tubes and then you want to step 00:24:47.16 --> 00:24:49. up from there you can add those onto the macro lens 00:24:49.89 --> 00:24:53. if you have a crop frame camera with cannon that's 00:24:53.06 --> 00:24:55. sixty millimeter lens that I would probably first 00:24:55.34 --> 00:24:58. look at and then there's also the sigma and I think 00:24:58.6 --> 00:25:00. tamara made one as well and so there are some other 00:25:00.93 --> 00:25:03. brands and so I think this like a lot of the other 00:25:03.79 --> 00:25:07. lenses you start basic and get more advanced as you 00:25:07.33 --> 00:25:09. get more proficient in your skill set and what you're 00:25:09.9 --> 00:25:10. doing with macro 00:25:12.2 --> 00:25:14. so maybe one more done and just tow get people's heads 00:25:14.87 --> 00:25:17. wrapped around this who have maybe ah ah, full frame 00:25:17.85 --> 00:25:21. camera, or have a crop sensor camera, salsa guy says. 00:25:21.33 --> 00:25:24. So would you suggest using a crop sensor camera for 00:25:24.48 --> 00:25:29. shooting macro shots with a macro lens instead of 00:25:29.07 --> 00:25:32. using the full frame camera, I've quite frequently 00:25:32.91 --> 00:25:35. will choose to use a crop frame camera. When shooting 00:25:35.33 --> 00:25:38. macro. Itjust enables you to get a little bit tighter, 00:25:38.56 --> 00:25:42. narrower angle of you. If the crop frame camera meets 00:25:42.01 --> 00:25:46. your quality needs, it gives you a little edge when 00:25:46.04 --> 00:25:47. it comes to close up work, because you don't have 00:25:47.46 --> 00:25:49. to be quite as close to your subject or you can get 00:25:49.59 --> 00:25:51. closer. So that is an advantage.
