Just now getting into the world of buying lens and thinking about getting some older ones for my setup but had a couple questions.
First of all what are the different mount types for canon cameras?
Second can these be used on Eos systems?
What about these adapters I see on ebay, mount a (insert brand) lens on your canon Eos... do they work? Good Idea? Bad Idea? |

| All Canon EF lenses work on all EOS cameras. AF lenses don't, EF-S lenses only on some (I think 350D, 20D and 30D). I use an EF lens bought 12 years ago with a Canon EOS 100 on my 350D. Adapters, at least those built by Novoflex®, should work; a friend of mine has a Canon 1D and uses Leica lenses most of the time. |

EF-S obviously also works on the 300D. You probably know that though.
What a great link to check out! Thanks!
EDIT: opening my eyes answered my question.

The only camera that is more universal than the EOS mount is the 4/3rds (Olympus) mount. With its large bayonet and relatively small register, the EOS can mount and use many different lenses if someone makes an adapter. Theoretically any lens that has a longer register can be adapted. Check here for registers of other camera systems.
I've used Nikon lenses on a Digital Rebel 300 before I could afford my first D100. Currently I use several M42 lenses as well as Nikon lenses on my Olympus cameras. There is a lot of great and cheap Zeiss glass in the M42 mount.

Goldenhawk...
To clarify, when people say...older lens do not work on Canon EOS mount. It's not that the lens does not work. The Canon mount is quite versatile. In fact, "Corpse Bride" was filmed using a Canon 1D and Nikon lenses.
The issue is that you lose such features as metering and auto-focus. But I've found people worried that they won't be able to use this really nice old lens they have because they've been told that Canon changed the mount and old lens' don't work on it.
When Canon changed the mount, they made it extra wide. This allows a lot of adapters to be purchased for mounting other lens types on the Canon EOS system.
Most of the time you will lose auto-focus/metering/etc. But if you've got an old 400mm manual lens without metering. Then it doesn't much matter - does it? You just buy a $20 adapter and mount the lens. Meter/focus manually just as you would have with said lens 30 yrs ago.
Now the real issue is during the transitional period when lenses started to meter, auto-focus, etc. And in those cases said function will be lost.
But if I recal correctly, the old Canon FD lenses were for the most part manual focus (though a few later ones I think added auto-focus). So in most cases you losing auto-focus is a moot point.

The problem with FD lenses on an EOS mount is that unless the adapter has a glass element (quality issues?) infinity focus is unobtainable. The FD has a register of 42mm where as an EOS has 44mm. I'm not a Canon expert, but I'm pretty sure Canon never produced AF FD lenses unless it was some esoteric like Nikon's F3AF & lenses. |

| Do you loose any speed from the FDs if you use a converter? |

I believe the converter does change the effective focal length somewhat, so yes, there might be some loss, but to what degree I don't know.
In any case, the FD to EOS converter is really not a good idea at all for most. Much better to find non-Canon lenses that can more easily be adapted and don't needoptics in the adapter.

I can understand losing auto-focus, but why would metering be an issue?
For auto-focus the body needs to be able to communicate with the lens to run the AF motor, but metering is body side so shouldn't be affected (although you'll have to set the aperture by hand)?
I don't have my 20D to hand right now (it's on holiday...) but I'm fairly sure that metering works just fine on my M42 lenses. |
