Aperture Control and General Info

All right, we've been talking about these d g and e lends us, and I just kinda want to hammer home the point make it really, really clear. So this is where that aperture control comes from, and so in a d lands the aperture setting could be on the camera and lens because we do have a ring here, you can mount this on a newer camera, and you can control the aperture straight from the camera you consented to f eight eleven and what you do with lenses. You said it, too, the orange number usually sixteen or twenty two, and once you haven't set there the lens, then kind of turns control over to the camera's faras controlling the aperture, the new g and e lenses you need a camera that I control the apertures, and so you can't take these g and e lenses and go put him on an original nikon f camera, you're gonna have exposure problems because you can't change the aperture over here. There is a mechanical linkage there's, a lever connecting the camera and the lens from the d and the g ones it's th...

is new e lands that has an electronic mechanism in it, and it needs elektronik from the camera to send the signal on what to do. In the power to do it because the motors are built into the last and so, the key things to remember on this is with the villains. There is some limited compatibility with the manual focus and early auto focus cameras with the lens is limited compatibility with early digital cameras and before nikon uses a lot of letters and it does get very confusing, so be aware that I have called this in the lens. I'm not sure if that's the official name with it be aware, though, that nikon mayday siri's e lenses, which were very famous and favored by people who liked very good value in their lenses. Back in the nineteen seventies, they were small, lightweight, affordable, siri's avian so we can't call this a siri's e because they already did that many, many years ago, and don't confuse that with a siri's e camera because that was a special project with fuji. It was one of their first digital conglomerations it was ten thousand dollars for a one point three megapixel camera. Don't you wish you had bought that one and held on to it? And so there's a lot of serious e letters and things that go around when it comes tonight, so finally we talked a little bit about these internal reflections. There's a lot of other things that made me to do about battling all this light bouncing around on the inside of the frame, the design of the barrel, the codings and flocking that they put on there which is this kind of very matte thick, crumbly surface so that light doesn't reflect off of it. They even have sometimes apertures that clothes a little bit to block light in certain areas when you are zooming the lens or focusing lens to prevent light from hitting the wrong area inside of the lance and so there's a lot of very advanced things that are going on in there now some kind of correct terminology for you is a zoom lens is a lens that can change focal length but maintains focus and while you may think you own a zoom lands, chances are you do not. Chances are you really own a vera focal lance a lens that changes focus as you zoom so as you zoom back and forth, the focus point is slightly shifting now on the early cameras they made real zoom lenses, which was great because I could zoom in focus and then zoom back and I knew everything was held in place in order to make the lens is smaller and simpler to design they're using a very focal design and this is very hard to figure out is my lens this or this that's pretty much impossible. Find you contest your lens to see if it maintains focus. Most of them do not. Some of the zoom lenses will have a little lock on it so that if you're walking around for travel photography, your lens doesn't sometimes that kind of troops out on you and so just for convenience, you can lock it in the shorter position, so it doesn't, uh, slip out on you. Okay? This is the last slide, and I need to ran. Do I have a cell phone? Can I get an apple box? I'll just rant from here. Okay? I've got a problem. Nikon. I got a problem with the way your name things. Let's. Take a look at the way you name your lenses. Here is a list of nikon names nike or thirty five. One point for you. Gotta put night car in front of everything. Okay, fine. You're proud of your heritage. I understand that I accepted next one f s okay, it's, an autofocus lands it's got the new silent wave that's a really important feature that makes a certain sense. Nike or thirty five. You want to know about that? The one point for g the g is a little one of those. Oh, yet also does this that looks pretty good, too. Dxe okay that's very important because now we know which camera bodies that's going to work on a very important nice job nikon this is this's okay it's acceptable let's take a look a little bit further down the line all right, so there's a couple of things number one zoom nike or seventy two three hundred you don't need to tell me it's a zoom I can see it's a zoom this one's a zoom but you don't tell me it's a zoom so why did we add the word zoom here and this I complained because when it's listed at all the places you by you got to get the name just right sometimes and v are okay I want to know what happened here I really want to know what happened because you got v r at the end of it which is where it should be but why do you put it in front of the zoom here in here but behind over here you should really have a standard and stick with that standard. And if I had to guess I think somebody in the pr department was very good friends with somebody in the naming department and when v r first came out they said, you got put us before the number we've got to get ahead of the number were so important and they go okay, you could be ahead of the numb but then a little while later they said you got to go to the back of the bus you got to go put your letters back there with everyone else and so as I tell you this because later on in the class when we go through all the lenses I've taken the v r here I've put it at the end I've renamed the nikon lenses I'm dropping the nike or you know it's nike or I'm not calling him zooms because you know if they're zooms and so they've got kind of some very funky naming system and nineteen you should really clean your act up because this is a disgrace this is just a disgrace you way back in the beginning of that section talked a little bit about breathing issues focused breathing issues did you say that micro macro lenses are the ones that have serious breathing issues? I might have said that the already today well, they're the only reason is because they tend to have a lot of focusing distance between the near focusing and far focusing so they're more likely to you're more likely to see it in them than in any other lands now one of the things I will clarify is when I talk about focus breathing there's something else that's related and when you have a zoom lens like this that zooms in and out if you think about this just that's something different that's something completely different because I am sucking air and pushing air in and out of this lands. And you could call that folks breathing down on some of their big lenses. You could get a it's hot and you could I can actually feel a little puff of air coming out of here and that's not focused breathing. Focus breathing has to do with a magnification change. When you are focusing and you, it will be more apparent on macro lenses, then any other lenses. Great. Thank you. And comment from lisa harris, man who says I so agree on the nikon lens nomenclature. Very confusing when trying to research compare lenses and if a professional is khun e o lets see. So we talked a lot about what we talked about cinema lenses early on, but I have some questions about the best lenses for both video and photo. If you're not going like full cinema, do you have that coming up and, well nigh cons lenses are really designed for the still photographer, and there are a lot of people who prefer the nikon manual focus lens is because the focusing throw on well, first off the folk scene ring on this particular lands is close up to infinity, so it's a little more than a quarter turn not that much, and this feel of this is very plasticky are plastic, and one of the things that I loved about nikon manual focus was the quality of focusing smoothness on a nice lands. And if you if you want to buy a used manual focus, lands, you gotta focus it. You've got to turn it and like, if it's got sand in there, just since ship that that's like fingers on a chalkboard for me, you know, getting that sand, and they're just terrible, and the good ones are just buttery smooth. Just turned butter with it. Really nice.

Ratings and Reviews


Outstanding class! This is a must own. You will refer back to this class many times during your photog career. John has put a ton of work into this class and it shows. Being able to download the slides and other Nikon glass info is wonderful. Even if you're not a Nikon shooter you will still gleam tons of information from this class, John covers in great detail the strength and weaknesses of each lens and when you might consider using it. I was expecting a good class, but this turned into an epic class. I watched multiple videos several times. The only bad thing I can say is I "had" to order a few more lenses! Thank you John Greengo for making a truly amazing class.

Wow! What a course! Very in depth, lots of valuable information. John instructs with great knowledge and integrity. I have taken other online courses, NOT from Creative Live (my bad!) and was left feeling like a monkey who had learned tricks without understanding or knowledge. Now I feel I have the confidence to move forward on my photographic journey securely knowing how lenses function, what to look for and what price range I can expect. Bravo John! I'd love to see a 2020 update video as an addendum.

Finally I have some sense of what lens do, know what I have, what I would like to have, what lens to use, and how I can get images that I see. Best part of this session is it was made so clear, simple, logical, and practical. I am glad that I purchased this product. Now, I am going to look for more from John Greengo so I can take better understanding and take better images. Thank You.
