I mainly use this lens with my N90s film camera, but I have also used it with my D70 for undewater photography (ikelite housing), though I seldomly use it with my D300. It is an excellent lens, with superb edge-to-edge resolution and very light. The fisheye distortion is a lot of fun and provides a very fresh perspective. It suffers a little from chromatic aberration, but that can be easily fixed in post processing. You can also tranform all fisheye pictures to rectilinear with postprocessing software (I use lightroom). It´s an expensive and niche lens, but one that has great resolution and is so much fun to use!

While the lens is great, Nikon should really figure a way to keep a lens cap on it. What they provide easily falls off leaving an expensive piece of glass exposed. It does make some great shots though.

Great build and fine shots when stopped down to about f5.6 - f8. Gives character to certain shots.
