This one is a good one Not everyone wants a fisheye lens. It's one of those 'special' lenses outside the normal range. If you're shooting lots of landscapes, then this lens gives you more versatility and wider range than those from Canon, Vivitar or Nikon. And it gives you really great results. This lens is designed well, manufactured well and works well. If you pay attention to the way you line up your shot, it's almost as if you've taken a 'normal' picture instead of a wide-angle shot. Put the midline down the middle of your subject and everything stays in proportion. Great for those landscape shots you used to make multiple passes on with your other lenses. If you're trying to capture more of an interior space, then the very edges of the shot will be curved inward. That can be fixed with software, to straighten them out and make the edges parallel. The image is very clear and will blow up well. Color transport through the lens matches extremely well with what you see. In short, I think this one's a winner.Read full review
New favorite lens... The lens was exactly as described, shipping was fast and hassle free...By far my new favorite lens on my Nikon D7200!!! Best optics for an amazing price...
Love This Lens ! For scenery, this is the best lens I have found. The distortion inherent in any fish eye lens is not noticeable for distant scenery. Very sharp.
