Summary: The item was as described and thanks to Amazon checking to make sure the lens was compatible with my camera. This made my purchase easy. It's a great wide angle lens, great for long exposures at night. The infinity setting is properly calibrated for easy use.
Excerpt: This lens deserves 5 stars mainly because of the excellent performance for the price. I have used the Nikkor 14-24mm f/2.8 and 16-35mm f/4 on several jobs and they are great and give very sharp images with well controlled vignetting/distrotion. This Tokina 17-35 f/4 has given me beautiful images with very good contrast and color. It is slightly less sharp than those two wides mentioned above.
Pros: Consistent Output, Durable, Easily Interchangeable, Fast / accurate auto-focus, Lightweight, Strong Construction
Summary: This lens is quite compact, though not very light weight, and solidly built like all other Tokina lenses. Optically it's superb. Very sharp and high resolution across the frame wide open. Best part is the distortion: probably the lowest among all FF UWA lenses, which means you can do architecture shots without having the stupid curved lines and having to do post processing to correct it. The filter is a little huge at 82mm.
Excerpt: Love this lens, It's perfect for doing indoor stuff like real estate photography. Also have used it for automobile interiors, and just general wide angle perspectives for auto exteriors, skateboarding, action stuff, etc. I've never felt like this lens was holding me back or stopping me from getting a shot I wanted.
Pros: Consistent Output, Durable, Easily Interchangeable, Fast / accurate auto-focus, Lightweight, Nice Bokeh, Strong Construction
Excerpt: Today I was looking at the Canon 35mm f2 and last week I bought and returned the Canon 50mm Macro f2.8, both of which I would have used to shoot food, food scenes, restaurants and markets, both here and in Spain. I decided against both after giving it some thought and doing some more research. I have this Tokina 17-35mm, which focuses as close as 11", the Canon 35mm would have gone to 8", but that not enough to justify a $[$]outlay when I would seldom use the lens.
Pros: Consistent Output, Durable, Easily Interchangeable, Fast / accurate auto-focus, Nice Bokeh, Rugged, Strong Construction
