This lens is compact and lightweight. I used the new version, which has no visor, which is more convenient with full-frame cameras. It also offers a lot of flexibility if you have 2 cameras, an APS-C and the other full-frame. In this photo made, with a full-frame camera, I placed it at 12mm and took 4 photos. I like it, but I prefer the Nikon 10.5mm.
