Holy Rokinon Batman!

A few tips for using this lens. The depth of field is extremely deep. With the right setting objects will be in focus from 3' to infinity. I taped a small piece of paper on the lens with a line that indicates where the infinity mark should line up. Set it and forget it.

Widest aperture is f/3.5 but if you stop down to f/4 there's a big difference. The image is sharper, especially in the corners, and vignetting is much less. Stopping down to f/5.6 offers slight improvements.
