Sigma 14 mm Art

Will be going to 5 day northern lights photo trip next month. Will post some from that trip then to see how it performs on real auroras, not these mild southern ones

Cool! I see a touch of coma in the corners of the last shot, which I notice was taken at f/2.0. But it's very little, and certainly less than my Canon 24 mm prime at f/2.0 (although the wider angle makes coma automatically appear smaller).

There is some definite coma, but it isn't bad and is gone by f/2.8. That shot is where it was most prevalent out of those that I took. I think because there were some brighter stars in the corners. A few other shots, even at f/1.8, it was much less noticeable, but dimmer stars.

Quick example:

I look forward it to it! Granted, I had a moonlit night, but I was pretty impressed with how much light the Sigma gave me. The minimal of vignetting was very impressive and useful.
