Review on Rokinon Special Performance Ultra Built by David Bowens

This is a MANUAL focus so it's understandable but for what it is it's great! If you want to try your hand at astrophotography, don't wait and just get this lens! Unlike its 2.8 cousin, it has electronic contact, so the aperture is controlled by the camera and all EXIF information is there. I've also used this in daylight for general photography and for still subjects you can get great shots. The camera even confirms focus, which is nice.
