Bests & Worsts Reviews from Amazon

I bought this for a 4-corners trip anticipating starry skies. I didn't know there was monsoon season in the american southwest. So I had one good clear night. It is a great lens for astrophotography (i think, I'm just learning)and for landscapes and big skies. Colors are nice and good contrast. I tried using this as a walk-around lens and ran into huge problems with the manual focus. I'm 50 with bad eyes. I can manage a manual focus Yashica 50 and 28mm pretty well, but this lens has such as wide focus range and the view is so wide, large turns of the focus ring make imperceptible changes through the viewfinder, so tons of my pictures were out or focus. When it was in focus, I was very happy with the results. If you can afford it then an autofocus option may be better if you want to use this for more flexible needs, but if just using at infinity then I can't imagine a much better UWA lens at any price. These were all shot with on a canon 6d
