Question: Will this lens work with D5100 body a DX crop?
Document: I also bought this lens to use with my  XTi (400d) on my 360 panorama rig. Its fantastic for not only that purpose, but lots of creative work as well. It is a great addition to my lens collection and I know a few pros using it for pano work as well.Enjoy!
I work in the VFX industry doing computer generated imagery for multi-million dollar movies and this lens is not only a must have but it's the best one you'll find. Very high quality, consistent and a work horse.I'd also recommend using this lens in other professions. Perfect for making 360 degree Quick TIme VR movies.For fun.. this is a HUGE hit at parties.
I purchased this to work with my Nikon D90, and it works perfectly its the cheapest I could find. but works better then what I have used.
Very fun lens! Good color, sharp, great distortion. I have a Canon Rebel XTi and with the 1.6x crop i needed something with a lot of distortion. The vignetting can be pretty annoying because you have to edit every photo but it's no big deal. This is a good lens and I normally dislike Sigma.
Good quality but on my Canon 5D, the circular image is pretty small. I was hoping it would be snug top-to-bottom to maximize pixel count. the lens may have been made for a 1.3 or 1.6 crop factor DSLR. That said, it's a HUGE improvement from my Nikon FC-E8 on a 995.
(I use this lens with a Canon 10D)
Works great for me as a Goole Trusted Photographer. I shoot virtual tour of businesses. The clarity of this lens is excellent.
Awesome lens for 360 virtual tours or unique fisheye images. I recommend this lens if you are shooting 360 tours.
This Lens is great for artistic photography and panoramic enthusiasts :D It help build panoramas fast and with great quality. I recommend ir a lot!.
I'd like to see the single-piece cover with some kind of thread or another more reliable connection.All in all, it's an excellent product regardless its relatively high price for a "toy" lens.
Answer: Yes it will work.
