Robust and Rock solid

I have the Tokina now for about 3 years in use. Used it on my Nikon D90 and D5100 on my (here without AF motor, but the image quality does not detract from ... on the contrary!). Yes, the lens is perhaps not quite "rough around the edges", but met with me exactly its purpose. The focus is in my opinion superior with appropriate use of a tripod. And here I have to use not only the excellent price / performance ratio. The light intensity is very good and the bokeh effects that it produces, sometimes surprise me still. As noted by others, think also I the limit setting as a great thing. The price is right here really. I recommend it very clear.
