|Mounted on Sony NEX-7 with Nikon to NEX adapter - looks huge|
On DX, APS-C or micro4/3 cameras it makes a great wide angle manual focus lens.
There are times when no other lens will work. When shooting indoor architectural photography this lens shines. It will make the rooms look big without adding any distortion.
For HD video this lens can make some wonderful wide shots for indoor sequences. In fact, this is my favorite lens for indoor establishing shots - it's wide enough to include everything you might want to include in a room, with no linear distortion. Your just going to have to move the lights a little farther away from the subject.

Below is a comparison of the Nikon 15mm f/3.5 and the Nikon 50mm f/1.2 lens. Both photos were taken at approximately the same distance from the subject. I'm standing close to 5 feet from the back wall, and a little more than 1.5 feet from my son Hatuey.
