Oh my god. This lens is PHENOMENAL. I've had it for a few months now and it's my main lens at the moment. It is excellent for many different wide-angle applications - architecture (indoor and outdoor), panoramic, landscape and astral photography. Photo quality is top notch. I can't say enough about this lens. It's perfect for the amateur photographer and won't break the bank. I like everything about it. With this lens you can get very close to your subject and still capture it completely without sacrificing quality, distortion or almost any corner curvature. This is an ultra wide-angle lens that doesn't look like a fisheye lens. Unfortunately I don't have my camera here to upload and share full res photos so please excuse the low res versions I'm attaching for reference - they are primarily intended to show the versatility of this lens. Image quality is MUCH better than these lower resolution versions can show. The copper head shot in particular gives you a great idea of what this lens can do - I was standing on the pavement about 6ft from the front of the building and I can still capture it in its entirety.
