Tokina 17mm f/3.5 AT-X 17 AF

Excellent FIsh Eye Lens Been using this for about a year, really good quality, sharp image. You get 180 degrees field of view at the 10mm setting. Recommended.

A very sharp lens I bought this lens to shoot underwater images. It has a very good reputation for underwater photography. Despite being a dx,some photographers will use it on their full frame bodies. I have enjoyed taking very nice and sharp images with my sony a6300, coupled with a metabones 4 adapter. Its ability for very close focusing marks it as unique since many lenses do not offer this feature.

Good for the buck really good lens Perfect lens is is ideal for Underwater Photographers, nice colors, it can be a little bit sharper and I will like it to focus faster but over all is the best fish eye you can buy for the money and to take beautyful underwater pictures
