Mount System & Lens Grade

All right, so in this section, folks, we're going to getting into the technology and the lens review, the actual lenses themselves. And so, this is gonna be a good time to have the class PDF, it comes with the purchase of the class, and there was a lot of lenses, and we work really hard trying to get the lenses listed properly, and so what we've done is we've actually changed the order of the lens in the PDF. And what we did here, is we were thinking, you know what, most people don't own all six brands. Let's list all the Nikon lenses together. We thought that made a logical sense. And so all the brands are listed together, but we have the different categories, and all the different specifics, and we've tried very hard to get all the numbers and letters exactly right so that when we talk about something you can refer to it in the handout PDF that comes with the class. And so in this section, we're gonna be talking about the technology, what goes into the lenses. Talk about some of the ...

different features on those lenses, and then we'll get in and talk about what lenses are best for doing different things. And so we're gonna be talking a little bit about things beyond just focal length and aperture in this case. So when we talk about lenses, we want to talk about the mounting system on the camera. What are the characteristics of a lens mount? What's important? Why doesn't one lens fit on all the cameras? Why are they specific? Well, there's a number of things that are very important. First up is the connection system that has been made by that camera company. And a big part of that is how big is that opening cuz that's gonna determine what sort of lenses you can put on it. The flange distance is the distance from the mount to the sensor, and this needed to be fairly big with SLRs, but has gotten much smaller with the mirrorless cameras, so some lenses can go on all cameras, some lenses are very specific about which ones can be adapted to different lenses. There is the image circle. How big of image circle does that lens create? We talked about that at the very beginning of this class when we were talking about full-frame cameras and crop-frame cameras, but it's very true here cuz some lenses are for medium format, large format cameras, different, smaller size sensors, and so you ideally want to get something that is really, truly matched for the system that you are using. There are different lens grades, and these are not always clearly illustrated or named on the lenses, but there are a lot of lenses that fit into the Entry Line level of lenses, which means they often have plastic mounts, a lot of plastic in the lens itself, not the glass, but the construction of the lens around it. They tend to have slower apertures, they are very lightweight, and they're not too much money. Then we have our Mid-Range lenses, and these tend to have a little bit bigger focusing rings on them, they have metal lens mounts, and they have features that either make them more durable ... We're talking about things almost beyond just the glass, it's the construction of the lens, the ease at which it can be used. They start having distance scales on them, and they start being very practical for somebody who is into photography a little bit more seriously. And then we have our Professional lenses, and sometimes they have special designations, like Canon calls them L lenses. Nikon, not quite as officially, but they'll often refer to them as gold ring lenses, and there's different names through different companies in here. And here we have really top quality everything. Top quality construction, top quality glass, sometimes they're using very exotic glass, and when I say exotic glass, I mean it's difficult to manufacture glass. And they often have some of the best features or features that you may not find on other lenses out there, and so this is kind of a soft category that I created, and there are some lenses that fit right in between these lines, but you can kinda think of these in three different levels of lenses through all the different manufacturers.
