[Brightcolours]

Wide open and with well corrected characteristics, it coul be great for night sky and Milky Way pictures. The fluorescent distance scale will become very handy for that while AF lenses usually are difficult to set up at night to infinity.


But in "normal" daylight photography, the fast aperture will be challenging for every non-LiveView focus setup.

Again, it in not challenging at all, especially with a focus screen like the Eg-S in my 6D.
