Nah its the sensor size.

A few canons have 35mm film sized sensors (5D, 1D etc) but most have APS-C sized.

So if you imagine a full 35mm frame then crop the center out thats what your left with , it means effectivly you have a 1.6 multiplier on focal length but its not quite the same (DoF works slightly differently & perspective doesnt change).

I never use it.

Gotcha.....so to get a fish eye you're looking at like 8mm?

A fisheye is a fisheye... just wont cover as wide. ( fisheye's give circular images rather than wide/ultrawide square pics). But yes you need 'wider' on a croped camera.

I have a sigma 10-20mm which is effectivly 16mm wide(on my 350d), plenty wide.

Sigma do an 8mm fisheye thats effectivly 180degrees on a normal 35mm, about 140-150 on a crop.
