I have researched some on lenses that are great lenses for this type of photography. It looks like the Rokinon lenses do very well. I have an APS-C Cannon. It looks like the 16mm/f2 is really good, but would I be better with the 24mm/f1.4? The 16mm is made for crop sensor, but the other one is slightly faster. Which would be better? I'm going to rent one just wanted thoughts on which one might be better?
