If you were me, which lens would you buy? (24-105 vs. 70-200 f/4 IS)

I've never used it on a crop but I imagine it will actually perform better on one.

Why? In what way would it be better?

Edge sharpness and distortion.

Yes.


My only real gripe with it was outer portions of the frame. Mostly on the wide end. It was almost as if the lens was designed for a crop. It was just about where a 1.6 would stop that the image really falls off. CA, sharpness and distortion. 40-ish through 105, the images are quite nice though.

[Jon Ruyle]

Fair enough.


But of course, the equivalent of 40-ish is as wide as you get on a crop anyway.
