#12
I have the Tokina 11-16mm, and it's certainly a nice lens. However, based on the great reviews this lens did get in various places, I had hoped that the image quality with wide apertures would be better. I do some night sky photography, and stars look quite bad in the corners at f/2.8 due to the severe coma. The quality improves at f/4.0 and is already very good at f/5.6.



Obviously, night sky photography is quite demanding - stars, as perfect point sources, show up any imperfection a lens may have. For daytime landscape photography (where you usually stop down) or when you use a wide aperture to isolate the subject (and the corners are blurred anyway), the coma does not matter at all.



I like this lens, and use it a lot. Well, at least until some UWA with less coma becomes available... <img src='http://forum.photozone.de/public/style_emoticons/<#EMO_DIR#>/wink.gif' class='bbc_emoticon' alt='Wink' />
