I've no doubt that you will like that lens more and more as you get the hang of it. I must put a mug in my test-shot routine so we can enjoy the corner differences between our 15s!
Congrats on getting the Sigma fisheye. I would indeed be interested to see what a coffee mug looks like in the corner compared to DA15.
I do not believe there will be a great deal of difference over such a small are, but let's see.
Originally posted by selar There is a Sigma 14 that is 2.8, rectilinear and full frame. I have a copy. I also have the DA 15 LTD, but not sure why.
The Sigma 14 - 2.8 and Pentax DA14-2.8 are quite large and heavy. Besides, I do not need F2.8 at this focal length, and the compact size is important to me.
If I need wide in low light situations, I have an FA20-2.8 which is quite good.
Another point is that I have lost faith in Sigma due to some poor quality experiences in the past with some of their lenses, but that may just have been my bad luck.
