This is an excellent general-use wide-angle and a nice moderate wide on cropped sensor cameras. Be aware that this lenses uses the AF motor in the body so it will only autofocus on cameras that have motors built in (if you are unsure please inquire).
The lens is in excellent condition with moderate wear and works perfectly. The focus is smooth. The glass is clean and scratch-free. The aperture is dry and snappy. The filter threads are slightly dented but still take filters smoothly. Caps are included.
