3rd Party Lenses Overview
It's always kind of a strange third party, okay, first party, maybe me. Second party cannon, third party is some other group and so that's what we're talking about somebody other than cannon making lenses and there's a number of them out there. And so these other companies are going to compete with cannon by offering a better price for the similar product. They might offer you more features that you can't get with cannon, or they might even offer you something of better quality it's unlikely that you're going to find something that is lower price has more features and is better quality could happen, but it's likely to be fairly rare so that's how they're making a living so just real quick overview on who these companies are sigma right now they are. They are a japanese company there with largest independent lens manufacturer, so they don't make cameras. Actually, they have made cameras, but they make cameras for nikon and cannon and a variety of mount. There they make the greatest vari...
ety and the largest number of lenses out there. Cameron they've been around for quite some time another japanese company they do a lot of work in the industrial and security areas so they have a great history in lenses they make some very nice equipment as well takina is another one of the big three these of the big three of my mind as faras the auto focus lenses for canon nikon and so forth so token another japanese company that's been around quite a while they do a lot with binoculars, microscopes and some other optical devices so they're fairly well diversified whereas sigma really focuses on just camera lenses they don't do as much in the other fields of optics his ice is a german company that has been around way longer than everyone else but they make traditionally they've been only making manual focus lenses but they've been getting into auto focus lives lenses but the ones for cannon are all on the double check yes, they're all manual focus but they also make a number of other devices for movie making medical industry and they have a very very high reputation I when I think of zeiss I think of mercedes benz a ce faras quality when it comes to lenses a couple of other names sam yang is a korean company and this is kind of interesting because they they seem to be doing some test market e all this is a very big test marketing and so you'll see a lens under sam yang broken on and bauer and they're all the same let's we'll talk more about them as we get to them schneider is another german company that has been around for a very long time and they make some very highly specialized lenses which are very, very spending so they're a little like a a zeiss in some ways of smaller zeiss but they make a lot of custom lenses which are kind of interesting lens baby portland, oregon just down the street from seattle yea they make a variety of creative lenses and so there's some interesting things were not going to go through their full collection but if you're looking for something a little different just to have a completely different look they have some interesting selections there and then there's a variety of other small ones I'm just going to throw in this one new company I'm not quite sure how to pronounce it but I think they're calling themselves venus optics in the united states and their specializing in macro lenses it's a chinese company and anything that's coming out of china is just kind of interesting these days because they're developing and perfecting what they do so quickly that it could very well be a powerhouse of optics in the future and maybe this is a glimpse into that so if you're gonna buy one of these third party lenses there's a couple things to be aware of these lenses with maybe a few exceptions are reverse engineer which means they take a canon camera they take a look at how it's built and what do these electronics do and well they don't have the schematic plans and the design from kanan kanan doesn't hand over the blueprints to the camera they say well let's design this does it work on here okay we think it works on here okay yes it's good and sometimes can and will go in and they'll change something about the way that a new camera works and you take this lands and you put it on a brand new camera body and something doesn't work right and so there is occasionally an incompatibility problem and then sigma says arms really sorry we didn't know about kanan doing that in the future so we'll fix your lens and so many of these companies will go back and retrofit your lenses if they don't work and this has been a problem in the past it's a little bit less so these days it's not something to be overly concerned about but it is something to be aware of many of these aftermarket lenses don't have the manual focus override option and the manual focus override option this particular lens does have it means that when you're in auto focus and the lens is going to focus you can't just grab the focusing ring and turn it and so that if is something important to you you want to check out to see if that lens has that ability on what you're looking at, they tend to have a lower resell value because most people don't understand them unless it's pretty specific lens that has a good reputation. And so oh, it's, a signal lands it's, not a cannon lives, and so it kind of has a lower reputation, and so they khun in some cases be very good byes use because the value that people see is lower, but their actual working value is actually quite high, and it really convey eri from manufacturer, manufacturer and individual lenses because some lenses and some manufacturers are known to be really, really high quality products and there's no reason that sigma tomorrow token is ice, or anyone else cannot make a lens that is as good or better than canada when it comes to the optics. Now, when it comes to the focusing system, I think kanan always maintains an edge as faras this speed of focusing. And so if you're looking for the fastest sports focusing lenses, they're probably going to be cannon. But when it comes to other factors, there's a lot of other good options out there.
