Considering an ultra-wide angle lens
I am thinking about getting an ultra wide lens for a Canon full frame. I have considered stitching but for the scenes I would like to photograph the light changes too fast (Forest scene) to make it feasible.
Two considerations are the Canon 8-15 mm fisheye or the Canon 14 mm rectilinear. Both close focus to roughly the same distance. The fisheye FOV is 180 degrees vs. the 14mm with a FOV of 114 degrees.
My concern with the fish eye is distortion, my concern with the 14mm is its price and versatility.
Has anyone tried both and come away with a clear reason why they prefer one over the other? Or they really suited for two different applications... perhaps it isn't that black and white.
