The 10-24 range is ideal for my needs so it is a shame that the performance is not as good as the 12-24, even at 12-14mm. The MTF numbers would have suggested that it would be better. My copy is not. Since all four corners are nearly uniformly degraded I don’t think that I have a lemon, it may be just inherent in the lens design. I am tempted to call it curvature of field, but with the extreme DOF at 10mm even at f/5.6 I am not sure this would be a reasonable explanation.

While not as terrible as the sample images I have seen from the Tamron 10-24mm, my copy of this lens would not seem to be as good with flat-field subjects (aka brick walls as the other WA lenses I have owned. However, in real-life images with variable depth the corner softness is very difficult to see. Not sure if this is because of the possible field curvature mentioned above, or because it is very rare that I shoot something that has good detail all the way to the corners.

Overall I am a bit disappointed. Given the price it should have been unambiguously better than the competition. Not 2x better as other reviewers have suggested, I am prepared to pay a decent premium to Nikon just for the consistency of color rendition I would get between this and my other most used lens (70-200). However, my expectation was to be able to say “about the same as the Sigma 10-20 in most respects, better at X and Y”. Right now I am not sure what X and Y would be, at least in comparison to the excellent copy of the Sigma 10-20 I used to have.

I will probably end up keeping the lens. The 10-24mm range is just too convenient for me, and there is no way I would consider replacing this with the Tamron 10-24, which is absolutely terrible in the corners at 10mm according to numerous reviews.

In summary, they didnt know how to use a wide lens (that is the many problem for anyone that can’t use anything from 8mm-35mm). Other say the construction of the lens differ. Well that is true but for people that take care of their lens and not looking to drop it, you would be fine but still that reeason this dumb.

Here is my professional summary from a professional photographer. I brought this lens to complete my “all purpose travel kit”…lol. I have the 10-24, 24-70, and 70-300. What else do you need. besides for Nikon to come out with a lens that shoot 10-24 at 2.8 and lower.

For now with that, you can just invest in the 12-24mm f/2.8 if you can. I dont have that lens yet but soon I will but I dont really need it now with this 10-24.

People would say “what about low light?” I would say use a flash. Others would say “what about situations in which you can’t use a flash?” I would say use primes because with primes you can get f 2.8 to 1.4 autofocus and the results are great. I have a few primes and I am not selling them.

Anyways, 10-24mm….great investment. I shoot models with it, landscape, and soon other things. Great investment and it’s SHARP.

In final, If you know how to use a wide angle…..using this super wide lens will be a walk in the park. If you don’t, learn or ask a real professional the main reasons for wide etc.
