Customer Reviews

Great lens
This lens is by far my best lens yet! Not to mention that it was really inexpensive compared to store prices. Definitely a must have in your lens collection!

Excellent alternative to what Nikon doesn't even have.
This is an excellent lens with very sharp optics. Bokeh is matter of personal taste but, I have that I really like the bokeh from this lens. Besides the cons I've written, I like everything about this lens:
Cons:
can used only in cropped sensor camera.
Min aperture is f16. Sometimes I want f22
It doesn't focus fast as some of my AF-S (pro level) lens

Until Nikon comes out with fast WA, I guess I will be using this one for while.

Great lens. No qualms with it.
Bought this for my Nikon D40. Very fast, sharp wide open, and perfect focal length for me for indoor shots. For the cost, its can't be a bad buy.
