Which sensor "full frame" vs. APS-C (1.6 crop) gives more distortion using the same lens? I mean, would a 10mm lens on a full frame camera show more or less distortion than if it were on an APS-C (1.6 crop factor) sensor camera?
You see, I have a Canon T3i (APS-C) and would like to time lapse the milkyway with out a lot of barrel or linear distortion. I've been looking to get the Rokinon 14mm lens but found that it only has 81.2° of angle (FOV). I'd like a wider lens with a larger angle (FOV) to accept as much of the milkyway in the FOV for as long as possible, but without too much distortion.
