Lenses and Accessories for the Nikon® D750
Let's take a little diversion into the world of lenses so there's lots of nice lenses available from nikon and winning the things you might want to do is you might want to put on a protection filter or a polarizing filter, and this particular lends the twenty four to eighty five uses of seventy two millimeter different lenses will have different sizes, there's a lot of common sized filters out there. The little nub nothing's around the front is for mounting a lens hood. This is going to block light that's just out of frame from bouncing around in the lens elements causing a loss of sharpness, a loss of contrast and possibly causing flare problems. So I recommend using a load lens hood now pretty much all the time, but especially when there is strong directional light available, our zoom ring for changing her angle of view and our focal length for knowing where that set at. Focus ring for manually focusing if we want teo and the better lenses have the distant scale so that you can see e...
xactly where you are focused at. We're going to go through some of that lens information on the next light our mountain mark so we know where to mount it up on the camera body and our electronics that we want to make sure our not obstructed or broken so that they can communicate with the body most nikon lenses, they're going to have one of two different types of auto focus switches on it. The m and a option is pretty obvious. Manual focus in auto focus the other em and em a option, manual focus and auto focus with manual override. And so the lens that I have to take a quick look at this one, this has the manual override on it, and what that means is that if I press halfway down, the camera will focus off if I could go to a steeper angle here so that you can actually see up here where the camera is focusing and let's, just get this set so it focuses, and once it focuses in, if I want to, I can manually override and take the picture, and so the medium toe higher in lenses will allow the camera to focus on its own, and then, while your finger is halfway down, you can refocus manually and take the picture on the low lower and cameras from night gone. You have to actually flip the switch out of the autofocus mowed into the manual mode before you turn the dial. If you turn the dial while it's in the auto focus mode on the lower end lenses, it'll feel really stiff, and you don't want to turn it because you're going to burn the motors in it. So the switch is basically just a higher and switch so that you could jump in and manually focus anytime you want so nikon ahs I say they love the alphabet they used so many letters in designing and designating what their lenses do let's go through some of the technology that nikon has out there so a f is auto focus that was pretty easy f s is there silent wave motor which is sometimes referred to as the w m silent wave motor si x is the sensor size in there really compact nikon one siri's cameras the original well not the original but kind of the second generation of auto focus lens is used a d after the aperture so it's a two point eight d which means that it sent distance information to the camera to help in the media ring system nowadays most of the time we're gonna have a g lands which does send that distance information but has a different meaning to it and then after that there is e electrical magnetic diaphragm and so there's a couple of new lenses notably the four hundred two point eight has an electro magnetic diaphragm on it which means that the opening in clothes and closing of it is done electronically rather than mechanically on most of the lenses it is still done mechanically and this is something that nikon is just starting to switch over now to a fully elektronik controlled aperture d x is the smaller sensors that are in the d fifty five hundred the t seventy two hundred for instance it is it used to be the high end glass from nikon this is tthe e extra low dispersion glass that used to be on the lenses that were, say two thousand dollars and mohr and that technology has kind of filtered it's way down and you'll find it on lenses that cost us little is two hundred fifty dollars these days a new type of coding that they are putting on too many type of lenses to get the best type of colors in the best image through that glass is a flooring coding there's only a few cameras that have that most of the cameras are going to have a g following the aperture number so f for two point eight two point eight gi and this is an electronically controlled aperture which means we're controlling the aperture electronically in the camera I have simply means that the lenses internal focusing it usually indicates that it's going to be pretty quick and focusing because the lens elements are smaller and usually moving less distance micro is a term meaning close up the nikon has their own siri's of micro lenses that are extremely good at focusing close up so I said before that e e d was usually the term that was put on very high end lenses now what you're going to notice is in a gold and for nano coating that means it's a high end lands and it's got a special type of coding once again just trying to optimize the optics in the particular lands nikon recently introduced their very first lens that has phase for now technology and I'm goingto I'm going to save going into the exact details of it of this tio my new class that's coming up called mastering lands but this is a new three hundred millimeter lands that is about half the size of the traditional three hundred millimeter lands and so it's a way for them to make a long telephoto lens in a very, very small package a lot of their lenses but not all have their vibration reduction. This is a feature that I very much like and I usually leave turned on when I am shooting hand held it stabilizes the camera and lens system, enabling me to shoot lower shutter speeds that I would normally be able to get away with so it's a great feature it does use a little bit of battery life, but I think it's well worth the extra little battery draw that it has a lot of the autofocus lenses that we're looking at these days are now second generation autofocus lenses that have the same focus same aperture and this is just the indication that it is the second generation of that lens and it is a little bit confusing because it is sometimes placed immediately after the v r indication of the lands and it doesn't mean that the lens has second generation v r although it may it means it's a second generation lens of that vocally and that aperture so with nikon lens is what you need to understand is that they have two different siri's of lenses, fx lenses and dx lenses and it's a little bit weird because the dx lenses are very clearly labeled as dx lenses, the fx lenses are not labeled at all, so look on the lands if it doesn't have a labeling, then it's an fx lands if it does, then it's a dx lands the fx lands is designed for full frame sensors dx lenses are designed for the smaller frame sensors, so is light comes through the fx lands it creates an image large enough to cover the entire surface area of that full frame sensor. The dx sensor has a smaller size image circle specifically designed for the smaller size image area of the dx sensor. Where things get a little interesting is when you start switching lenses you can mount dx lenses onto your d seven fifty the problem is is that they don't have the coverage to bring up an image in the corners and so you're going to get a darkening of the corners and so the camera has an option to automatically crop images to the dx format, which is probably a good thing, just cause the artistic look there's a little bit different. You may want it, but that is something that can be turned on in the camera that we will see. If you want to take your fx lenses and use them on somebody else's, dx body or the psc body, you'll be able to do that just fine. It's going to kind of create an image that is bigger than you need in your cameras, just simply going to record the middle portion of it. So let me talk about a few of my favorite lenses. The first three lenses are often referred to as the holy trinity of lenses. Thes air, the holy grail ends is thie fourteen to twenty four, two point eight, twenty four, seventy and seventy two, two hundred all two point eight lenses. Serious pro photographers really value that faster aperture of the two point eight. And this gets you very smoothly from fourteen, all the way up to two hundred, which is a great range. The fourteen to twenty four is more used for landscape photography, architectural photography. Ah, lot of the mainstay photographers will have the twenty four to seventy, seventy two, two hundred is there to kit lenses that they take with them pretty much everywhere they go I'm also a big fan of the f four zooms, and nikon has kind of recently brought these along the sixteen to thirty five twenty four to one twenty I think the twenty forty one twenty makes a really good traveling, so if you're just walking around town and you want to take one lens with you that reasonably fast, that has a reasonably good range that's one of my favorite lenses for that, and if you want a compact, really high quality telephoto lens with seventy two, two hundred four if you don't need that pastor aperture, that is a really sweet little lance, and so I'm a big fan of all of these lenses, but I'm actually more attracted to the slower lenses than the faster ones just because they often are noticeably less money and a little bit less weight and sometimes less in size. I think every serious photographer should have one or two primes in their kit, and nikon makes some beautiful prime or fixed focal length lenses. The twenty four thirty five fifty eight in eighty five are all just incredible lenses. If you are trying to get the highest image quality possible, you can't do really much better than these these lenses here, they're absolutely fantastic if you have a little bit of a budget in mind. I can highly recommend this new one point eight siri's from nikon. They brought out a number of lenses, many of them in the one point eight aperture. The fifty is the one point four, but all of these lenses are costing maybe a third of what the one point four lenses are. But when it comes to image quality, they are nearly as good and in some cases as good it's just that they don't let in quite a ce much light. And so you can save a lot of money by having the lens it's just two thirds of a stop slower those lenses on the top. Those one point four lenses in general are going to range between sixteen hundred and nineteen hundred dollars. The one point eight siri's is gonna range anywhere from four hundred twenty five dollars to seven hundred dollars, depending on the exact vocal link that you get. And so, as I say, it's about one third, sometimes one half the amount of money to get into those really good primes.
