i tried looking for it with no results. does it even exist? everything is digital it seems.
Im sure there are, you just have to look REAL hard. i think thats an older camera, FD mount?
if it's an FD mount, then I'm sure there are wide angle lenses... though you won't really find much like the 10mm that are available now. Back then 18-20mm was considered to be quite wide (of course it is 35mm, so it's much wider than the crop sensors now).
These wider lenses can be found all over ebay.
Here's an FD 20mm f/2.8 for $225:
That's equivalent to 12½mm on a crop body.
Here's an FD 24-35mm f/3.5 for $400:
I currently use a 28mm and that is plenty wide for me on the AE-1
Lenses are all over ebay but if you dont want to look I would seel you mine seeing as how i moved onto Large Format
Where are you getting your math?
A full frame 20mm lens (like the FDs) on a Canon crop body at 1.6x would be 20 x 1.6 = 32mm equivalent.
And since the AE-1 is a film body (thus full frame), the conversion is not relevant to the OP's needs...especially since you'd need a FD-EOS converter at the same time for any Canon digital bodies.
Where are you getting yours?
20mm on FF = 12.5 on crop.
Brian's right... with a 1.6 crop factor, you have to multiply 20mm by 1.6 which means a 20mm lens on FF is equivalent to 32mm on a crop sensor.
My observation about the equivalent field of view was directed to Nate's comments.
Obviously, 20mm is a very wide lens on the FD mount.
You all should probably read a little more carefully, the OP has a FF and is not asking about a Dx.
Isn't that backwards? A 20mm on a FX is 30mm on a crop body? (assuming a 1.5 crop factor, it could be more or less)
If his camera is FX... 20mm is 20mm, no conversion needed.
Oops, Mike_E beat me to it.
There's a 24 mm f/1.4 - a rare thing to have such a fast 24 mm lens. 24 mm converts to just under an inch if it is used on an Imperial camera.
