3rd Party Primes: Samyang
Sam yang also known as roque anon and bauer they're all coming from from the same factory they might just have different names on them. They're also making a group of lenses were not going to get into each lens individually but it's kind of interesting that at least here in the united states their marketing this under three different names but they're exactly the same length same lands don't worry about it uh sometimes once ten or twenty dollars less than the other just go for the one that's cheaper because it's the same lens so there's nothing to worry about there. So sam yang really is the company that is building the lenses. The top row is for their compact sensors, so if you have a crop frame camera, they have a wide angle, another white angle that's little bit faster and then they have a smeared lens. Cata die optic lands these air kind of unusual. We don't have any other lenses in here that are mere lenses, and so it bounces the light against a mirror in the back in the front and...
is able to create a telephoto lens in a very small package. But with all these mears in there, the optical quality goes down and it goes down enough that I don't know that I would recommend something like that it looks kind of interesting, but that that money is kind of getting thrown away very low quality on that, but these other lenses manual focus, and they are achieving very good quality, not the highest level of quality, but very good quality for much lower price. And what you're essentially doing down here is you are trading manual focus for money, so these air manual focus and they're going to be a lot less money. So for instance, if you said I really need a thirty five one point for night cons, lands is was fifteen hundred two thousand dollars. The thirty five one four check my notes here is around four hundred bucks, so it's, just significantly less money. So if I was a college student and I was working for the newspaper and I needed a fast, wide angle, the twenty four one four is going to get me in a basic lens that gets the job done for a fraction of the price. And so this would be a great way to build up to that nikon twenty four one for that, maybe someday you can say about four, but this will is it be used as a stepping stone or for portrait work? If you don't mind manually focusing, get in eighty five one four that's going to run eighty five one four wow I wonder if my numbers are right on this haven't I get in a number of three hundred bucks on that for an eighty five one for some very cheap stuff here and so lower lower and lens is a little bit in optical quality construction wise they feel pretty good not quite as good as an icon but pretty good so those are some of the other prime lenses that you can think about from your third party manufacturers now everybody comprehensive a tour on a prime lenses wow I've got love this comment that came in from somewhere and about now I need to go back and look att all of my whether it's old manual lenses or what have you now I know what to look for when analyzing whether they're ones that are still good for me to you so so many different facets of what this class is going to be so useful for let's see if we have any questions in here let me know otherwise raise your hand ask you questions don't be afraid um let's see a question that has come in about it seems that manual focus wide angle lenses would be a better way to approach a wide angle situation than auto focus do you agree I don't know that I strongly I disagree but I would say it's easier to focus wide angle than it is telephoto because you have a lot more leeway from the stakes what you use white angle for us for it depends on what you shoot, but a lot of times you don't have that rush to get that shot right now you you have a little bit moment it's more seen it where it's that's the scene, what it looks like and you have a moment for it to work with and so I am constantly using well, I use back but not a focus, which is something we're not going to get into, but it allows me to focus when I want auto focus or manually and so I feel free to be able to just go up there and manually focusing and so with white angles I am manually focusing that quite frequently I don't know if it's easier than auto focus, it depends on the situation thank you on so you just mentioned that we are not going to necessarily talk about back button focusing however we are going to talk about calibrating lenses, correct? Yes, because the question that come in was, is john going to cover how to calibrate a lens if it is back or front focusing? You know, I'm just curious if there is a difference when you're doing back button focusing knows where those regard too yeah that's separate issues because once you activate the focusing whether it's on the shutter release or on the back of the camera that is, ends up working the same. And so that there's no difference there, and one of things I will mention about, I guess, both back button and the fine tune adjustment where we're adjusting. The focus is that's, not available on all cameras. You have to have kind of a certain level of camera, intermediate or higher in order to do that, fine tune adjustment. It will be in your menu system so you can check your instruction manual. Or you can go through the notes in my classes on cameras and it's in there.
