Hopefully just a quick question regarding crop vs full frame. I am well aware of the differences and have been shooting for over 10 years.
However I have one question which I dont really know the answer to...
Is there a difference between 10mm on crop and 16mm on full frame when trying to take an identical image with each setup (ignoring any DoF differences)?
The reason I ask is that the corners of the UWA lenses distort heavily (by distortion I mean the "streetching" caused by the casting of the image onto a flat sensor by a rectilinear lens). Would this stretching be the same when trying to take identical shots with the setups mentioned above?
