Summary: Fun Lens
Comment: This is a great lens to get the whole picture. It is fast for indoor use and allows you to have a very shallow DOF for really blurring the backgrounds. Only downside is that it can have a bit of chromatic aberration, but can easily be fixed in post processing. The fisheye effect can also be fixed, but not as easily sometimes. This lens is a lot of fun to use and to get great special effect pictures. I highly recommend it.

Summary: Wide and Fast
Comment: I bought this lens in April 2008 to use on my D1X. I wanted a lens wider than I've ever used before and faster than the slow, variable-aperture zooms that are a fact of life with digital cameras. I've primarily used it for interior shots where the f/2.8 speed really helps. But my compact SB-30 flash has wide enough coverage to use with this lens for added versatility. I've taken a lot of photos wide open and am amazed at how sharp the lens is, even at the corners. But then I only make 8.5x11 prints which isn't a strain on any lens. I've also found that the fisheye distortion can be minimized on some subjects, such as interior shots, by careful composition. Most of the shots I've printed have been corrected using the Fisheye Hemi plug-in as a filter in Photoshop CS3. I like having the option of two perspectives; it makes this a much more versatile lens.

Summary: Amazing fisheye
Comment: Ok, you cannot use this lens all the time. But under certain circumstances, it is a really great lens. Good quality, very light, it is well made. And the pictures are just perfect. The wide angle is amazing and the fisheye give a great effect. If you wanna use some of your pictures without it, you can "defish" the pix with capture NX. So you have also a standard wide angle with this lens.

Summary: great lens, well worth the money
Comment: I've had this lens for 3 months now and love every second of it. Its sharp fast and makes almost anything look cool. the auto-focus is good, at night it does go all the way through sometimes, but most lens's do that. How close u can get to object is unreal, just make sure u take ur eye off now and then to make sure u dont hit the front of ur lens with what ever ur shooting. u could be 1 foot away from someones face and still get most of their body. highly recommended if u got the money
