I think being full frame is the difference. My camera body is a dx cropped sensor and my macro lens is for an fx full frame sensor. So at an aperture of 2.8 I find that less of my image is in focus using a dx sensor than I would imagine using an fx sensor. So many times I find myself shooting at f11 or f16. Which Cuts light by a lot. This is why I bump my iso up so that I can get a usable shutter speed. Hope that makes sense lol
