Distortion and vignetting

It's hard to judge about this on a full frame because I used the lens on the DX camera Nikon D3100. And in this case is a good performance. Tokina AT-X PRO 20-35mm 2.8 235 AF sample photos distortion

Personal experience

Despite the glow on wide open, lens really like. It easy to use, pleasant character and natural colors. I like the color rendering greater than that of modern kit lenses. The focal range is suitable for sequential shooting in small rooms. Also, it is convenient to shoot reportages, cityscapes, and architecture. Tokina AT-X PRO 20-35mm 2.8 235 AF sample photos city
