Lenses

Let's, go ahead and dive into the lenses and talk about what's going on with lenses on here and so there's a lot of different terminology I'll throw it a bit by bit, so you want to be looking for sony's, full frame zoom lenses and a couple of the basic ones to twenty eight to seventy five to eight to seventy two, three hundred these air, these are decent, good quality lenses that nothing that gets super exciting with the twenty eight to seventy five you know, a pretty good, solid performer. One of the terminology is that you'll hear is sam, if your name's sam, you gotta have your name on your equipment. What the stands for is smooth autofocus motor when it generally means in the real world it's going to focus fast and it's going to be very quiet in the way that it does all right now, one of the other things that's kind of unique about these lenses is that they use what's called a circular aperture, and what they've done is they've kind of curved the edge of the blades so that when they...

closed down, no matter what aperture, they closed down to it's as close to a circle as possible, and this is really nice for bo kay, so we're getting nerdy now and so it broke a is the quality of out of focus area in portrait photographers are really big into this because some lenses are good and some lenses are bad and there's a lot of things that affected from just what aperture is the lands to the glass quality and what it looks like out of focus but one of the factors that has something you can physically compare from one leads to another is how many blades are on it because the more blades means it's more circular and how circular it iscause if it's you know if it looks like an octagon you're going to have these out of focus areas that look like an octagon and so it's nice to have a nice circular aperture so I'm going to note that in the lenses as we go through them here all right some prime lenses so prime lenses is a non zooming lands it's a fixed lands and they make a a good collection of healthy collection of lenses and so here is some of the better ones I am not showing you all the sony lenses I'm showing you once that I think are particularly interesting so they have a couple of good macro lenses fast some white angle of fish islands back in the days of minolta they wanted to produce a higher end of lenses you might say kind of similar to the nikon and nano coding lenses or cannons ellen's is will they have the g lens what is g stand for will gringo of course I'm sure at least that's what I thought was I nelson could be yeah, I don't know what she stands for these often have another technology that you'll hear is s s am super sonic wave motor and it sounds like it's a fan wave machine for the seattle supersonics here who used to be in town but it's actually just another type of focusing motor that's very fast and very quiet and so these air lenses that are really at a very, very high quality level and so all of these lenses I would highly highly recommend and so we also have some big guns of this, so the three hundred two eight recently got reintroduced the new version to even better than before I heard a rumor have no idea if it's true, but I'll spread it apparently sony only makes ten, five hundred millimeter lens is a year and it's a very careful process and apparently there's like this one woman who makes him who's very meticulous about how they're made and you gotta wait for her to finish your lance. No idea if it's true, but it sounds nice something these lenses have is extra low dispersion glass this is just to get all the light hitting the right spot on the sensors so that you're getting the cleanest best lens is possible with the least amount of aberrations there are matching tele converters, one point four and to plano tele converters. You want to stick these tell converters on these lenses that's typically wearing? They're going to get the best out of him. All right for you and snobs. It's now time to being in the germans there's ice. All right, if you don't know, zeiss is a optical company from germany, they've been around for probably close to one hundred years, if not one hundred years, and they're known to make some of the best quality glass out there, and they have been working in conjunction with sony on a lot of glass, and now they are making lenses for their sony cameras in auto focus. Now you can buy zeiss lenses for your night cons and your cannons and other brands of cameras up there, but their manual focus they work exclusively auto focus with sony, and so they have a number of lenses, and when you're when you've got one of these rock in your camera, you know you're operating on full cylinders, they are mechanically just as good as you can get in auto focus lenses. And so having used a lot of the night cons and the cannons, I would have to say the workmanship on these is a little bit higher than I've seen on some of the other ones. You do pay for a little bit so you get what you pay for and they have a number of really nice prime lenses one thirty five one point eight, which is the fastest one thirty five on the market today both candidate can have that two lenses. This is one point eight just they're trying a little bit harder, but they have some really nice fast one force have two lenses, variety of ranges and have a couple of zoom lenses as well, very useful range is sixteen to thirty five. The lens that I have here in this camera is the twenty four to seventy very very nice lands I'm used to using a different camera, and I had to get used to the zoom zooming in the other direction, but that's, just one of those things you got to get used to when you're flipping around with systems and so forth, but just the quality of workmanship on the lens is just very, very nice. Obviously, optical quality is extremely high on these now something to be aware of is that sony makes a big collection. I'm just going to show you three of them here dt lenses. This is designed for their crop frame sensors, so if you have this camera, don't go out and buy dt lenses because it's for their one point five crop cameras and because you can use him, so if you are, was stepping up from another camera and you take one of the dt lenses and you put it on this full frame camera. The problem is, is that they don't have enough coverage for the full sensor area. Now, this camera will automatically go in and crop in, but you're not going to get the full frame. You're not going to get the twenty four megapixels, so it's it's a good option that you can use these other lenses if you are kind of migrating up in the in the sony system, but it's, not any great benefit, why you would go out and buy these lenses. There is another technology that we're going to talk about as we go through this and it's a f, d and f d stands for depth map assist mode there's, a special series of focusing points that we're going to get more into in the second half, and this is enabling the camera two focus faster to do that range, focusing that we talked about, and at the time of introduction of this camera, there was only six lenses that it could do this with. There is now a seventh lands, which is the fifty millimeter, one point four lands, but in order to get advance, take advantage of all of the autofocus capabilities, these air, the mainland's is that you want to look at now as they come out with new lenses in the future, they will, of course be making those compatible, but as to whether they go back and re chip some of the older lenses, it depends on in some cases they probably won't. And in some cases they may so just realized that if you want to use this new depth map assist mode and this is where we're talking about setting the range up between the two and it's also a focusing aid, which will help you focus in some other situations. So if you want the absolute best focusing, concentrate on these six lenses, so there you go. All right, well, we just have a few minutes to take some questions, then before we go to our break, any questions in the audience right now? Well, there were a couple that came in on line again talking about maybe upgrading if you've got a no older sony and you're thinking about moving up here. Betty b seven, twenty three says I'm a bit confused. I have a fifty five and I'm not quite sure where it stands in the lineup other than it being a little older. What are the advantages toe upgrading from an older sony to the a ninety nine? You've talked about a lot of the great features in your mind what are those upgrade benefits? Well, the big upgrade here obviously it's the full frame sensor and so that and once it changes everything but I do want to say that it changes it changes a big part about what you're doing. You're going to be able to shoot under much lower light conditions, you're going to have a cleaner, higher quality image now what you have to ask yourself about your current camera is are you getting the pictures you're happy with? Are they clean enough for you? Are you know the low enough noise? Do they have enough resolution for you to do what you want to do? That's one aspect the other aspect is the performance of the camera is the cameras auto focusing system fast enough for what you want to do is the exposure system the way you like to work with? And so as you go up the scale and I'm not super familiar with all the control layouts on that camera what this camera has which well, frankly, some beginners might not like is a whole bunch of buttons and they have is there's there's a lot of direct control if you have to press three buttons to do something that you do all the time that's probably their own camera for you you shouldn't take more than a couple button presses to access any particular mode that you want to get into and I know in a lot of the lower and cameras rather than to dials they just have one dial and so they have to press a button to activate the other one and for a simple beginning camera that's fine, but once you know what you're doing, you want to get in there and do it right then and there that's why the cockpit of a seven forty seven as like a thousand buttons on it? Because they know exactly what they want to do and they don't want to spend a lot of time turning this one on this one green now we can turn this one on, so the more you know about it, the more buttons you want that directly control each of the features you know but that full frame sensor that's kind of a big deal so that you can start shooting and I s o thirty two hundred and barely notice any noise at all kind of a similar question along the same lines from lisa castiel portland, she says she's interested in what you would say are the biggest advantages or disadvantages of this camera compared to equivalent nikon camera cameras well the biggest let's go with disadvantage that's easy one on the the digital viewfinder just isn't as good for panning subjects for sports shooting I haven't got quite used to it yet, you know I'm not saying it's not as good in the long run, but I haven't got used to it in my relatively short time my two weeks with the camera on, and so I still prefer an optical viewfinder over digital you find her although the digital viewfinder has advantages and, uh just kind of as a side note kind of this optical digital analogy is I used to do traditional slide shows with projectors good old projector and take a thirty five millimeter slides and I put it through a zeiss lands and it looked beautiful on screen and then when digital projectors came out it's like a thousand pixels across just horrible resolution, but there's certain convenience with the digital projector and now I have a digital projector that's hd quality it's not as good equality is optical, but I could do so much more with it and at a certain point for most photographers this will be good enough quality and they'll be so many things that you can do with it that's kind of both the sales point and the weak point of it the biggest let's see so that was that was that I think is kind of the weak point well, another weak point is that face it. The big boys on the block or nikon in canada and that's, where a lot of the lenses are, whether you're looking going into a store to find a new lens or you're looking on craigslist or ebay there's more stuff out there with canon and nikon and so there's less accessories. The advantage of the system. I think I think this is good for somebody who's willing to take a little bit of a risk. Who wants to do something different than everybody else. Somebody who wants to separate themselves in some way from the rest of the group that they're dealing with, and finding the features of this camera that allow them to do something that their competitors can't dio. And there will be something in this camera that you can do that your buddies can. And if you can find a marketing tool, if you're a business where it or if it's something you personally use, your gonna have a lot of fun doing that and there's a lot of things that are unique about this camera.
