Widest rectilinear lens for crop Anonymous
So the Sigma 12-24 is the widest rectilinear lens for 35mm/full frame digital.

What is the widest rectilinear lens for crop on any system?

Canon 10-22?

Sigma's 10-20 DC and Canon's EF-S 10-22 come to mind, but I might be wrong.

Are you counting fish eye primes or do those belong to the realm of curvilinear?

Well, when I'm thinking rectilinear I mean anything that's not fisheye.

If that's not the right term then I'll rephrase: What is the widest non fisheye lens for crop cameras on any system?

No, not unless it fits the 1.3x crop bodies, which I don't think it does.

Sigma 10-22 on Nikon or Sony 1.5x crop sensor is wider than a 10mm lens on a 1.6x crop sensor.
