Sigma 70-300mm f/4-5.6 DL-M "Motorized" DG Macro Telephoto Zoom Lens with Built-in Motor Drive for Nikon SLR Cameras Including D40, D40X, & D60

My daughter was excited to get this lens for her birthday. It was very good quality and very reliable service. I would recommend this company to all.

This isn't a pro lens but is very capable. I couldn't pass the price up. Very affordable. I got some great shots with this lens.

I recieved my lens about a month ago and have been nothing but pleased. It focuses fast, takes great pictures, and was very affordable. I have absolutely no complaints. My dad has a simliar Nikon lens for his D90 but admited after taking some pictures with my D40 that he did not see a difference other than the price which my lens was about $250 less. He is now considering buying one for my mom's D40. Excellent lens. I highly recommend it.

Being a novice camera owner, I needed a better zoom lens for my nikon D40 slr. The sigma af 70-300 lens is a good lens for what we need. It's a little heavy, but it performs very well. The pictures we've taken since receiving the lens are all clear and with a little getting used to, this lens is exactly what we wanted.

i bought this lense and i love it but i cannot get it to do auto focus... i dunno if i amdoing something wrong or what but i would love some help.
