First off, some photos (click for 100% samples):
17mm f/2.8 (no editing other than exposure correction and RAW-JPG conversion)
50mm f/2.8 (no editing other than exposure correction and RAW-JPG conversion)
First, let me say that $350 for a lens that will do constant 2.8 aperture is pretty much a no brainer. Just for the ability to take low light shots at different focal lengths, it was totally worth it for me. The image quality is pretty good too. Even the colors are more vibrant than the kit lens this is replacing. It's a fantastic lens. That being said, there is one disappointing thing. In my research, I came across a snip-it that said this lens had a weak left side. I didn't really know what this meant, since it doesn't make sense to me that a lens would have a weak side when the glass elements are round and theoretically should be the same quality in concentric circles around the center point of the photo. Sure enough, if you look at the photos (especially the park bench, you can see that the left side is slightly softer than the right. This trait appears to improve slightly as the lens is stopped down. All in all, I am very impressed with this budget piece of glass. It will definitely last me until I can afford some big boy glass!
Hope this helps!
