[QUOTE="aroy, post: 298321, member: 16090"] For astro photography, there is no need for AF, hence manual focus is fine. The focus ring is set at the extreme end if the lense is calibrated for infinity properly. I know a lot of people want extreme wides for astro photography, but in my opinion, a fast 50mm, say f1.4 used wide open will give lower exposure times as well as sharper images. You can always stitch images for larger sweep. [/QUOTE]
