Confusion between lens mount types

Hi there, HDSLR are not my favorite tools to deal with, but with my new job, I got to get used to it. So I got some questions, especialy for the lens mount types.

I know that there is different types like EF AF AE or something like that. We got a Canon Rebel EOS T3, not the T3i. It says it's a EF Canon mount type. And somewhere else it says it's a AF/AE single lens reflex. Sure the DSLR came with it's own lens to start with. But my boss want to have various types of lens. Witch I think is a good thing since we got contracts like taking profile pictures to Beautyshots in a helicopters.

Plus my boss bought an old 50mm Canon Lens from 1.8 to 22 f/stop, when I saw that old mount thing, well i'm pretty sure it won't fit...

I hope you could help my between differences of lens mount types. Like you saw, i'm a little bit confused!

Thanks for helping me out!

Well, I just got some information for some terms and the info I needed for the old lense is an FD lense. So anybody got clues where I can find and FD/EF adapter besides ebay and amazon? Thanks

FD and EOS have different flange-to-focal plane differences. The EOS distance is what make so many other lenses fit with adapters - it's a little shorter than Nikon, Pentax, etc., so there is room for a millimeter or two of adapter. However, the FD flange is such that an FD lens on an EOS won't focus to infinity, and thus those adapters have an optical element (a piece of glass lens) to correct this.

Thing is, there are so many really great manual lenses that fit EOS with adapters that you may want to consider looking at Nikon AI, AIS or AF glass, Pentax, etc. There's just a mountain of Nikon out there, many are classic lenses. A benefit of the manual lenses (pre-AF) is the focus feel is noticeably tighter, with more damping vs. the really slippery AF feel. So using a follow focus has a much nicer feel and more accuracy. All of these older lenses have aperture rings as well, which many people prefer on a DSLR for video.
 
Hey, just some thoughts on the terms you have seen. "AF" and "AE" are not lens mounts but mean functions: "Auto Focus" and "Auto Exposure". Your crop-sensor EOS camera uses the Canon EF-S mount lenses, though it can also directly use lenses for the Canon EOS full-frame sensor cameras, which are called EF mount (no adapter needed - basically it's the same mount).

If you want to use old lenses it is best to go for those which do not need an optical element in the lens adapter that you need to connect them to the Canon EOS camera - the following lens mounts use this preferred type of lens adapter: Nikon F, Pentax K (also called PK), Contax/Yashica MM, Olympus OM, M42 screw (eg. Pentax screw lenses), Leica R.

Unfortunately the old 50mm Canon FD lens that your boss bought, as Michael said, requires a lens adapter which needs an optical glass element, so would not be ideal to use on a modern Canon EOS camera.

All the best.

Hay Samuel, which mount is best to buy with new lenses then?

Like for instance, if i get a
[h=1]Rokinon 35mm T1.5 Cine Lens[/h]
it can come in either a nikon mount or a ef mount. Maybe now i want to use it for my canon, but later i might want to use it for a Sony camera.

would it then be wise to buy it in a nikon mount and get an adaptor for the canon, or should i buy it in a canon eos mount and get an adaptor for the nikon mount.

which mount is more accesable to be adapted to the other mounts without having to ad an adaptor with glass?
 
I bought my Samyang lenses in Nikon mount. But I went for Leica-R lenses for most of the range (35mm onwards), those have an awesome image and work on nearly everything.

Definitely better to get glass for Nikon and adapt to Canon than the other way around (since that requires a glass adapter, which means I'd rather sell the lens and buy a new one with the desired mount). But glass for Nikon won't work on Sony A or Pentax K, for example.
