(More customer reviews)I hesitated purchasing this lens for my Nikon D40X--probably looked at this listing six or seven times before making the purchase. Truthfully I was worried about how inexpensive it is. Now, I'm probably a pretty average amateur photographer in that the majority of my pictures are family stuff: kids' sporting events, vacations, birthdays, and the like. But that doesn't mean I'm willing to compromise on quality just to save some money, and I know that the Nikon 55-200 is a quality lens.
But, I purchased based on Michael Del Priore's review (his was the only review at the time)--I figured, at this price (especially when compared to the Nikon 55-200), why not give it a shot, and I'm glad I did.
This is an excellent lens. The auto focus motor is fast and doesn't chew up the battery (I was concerned about that, but I shot almost 170 pictures at my son's games two Saturdays ago and didn't use any more battery than the Nikon 35-70 lens that came with the camera). Like "cinderoo" I haven't had any stabilization issues to speak of either, even snapping away while following 12 year old boys run the length of a field. That may be more of an issue with macro photography, but I'd imagine most of the (admittedly limited) macro photography I'd do would probably be with a tripod anyway.
Now, no one would mistake me for a professional photographer, but I can tell you that when I pull up photos shot with my D40X and this Sigma lens on my 24" iMac and view them full screen they are *everything* I was looking for when I decided to move to an SLR camera.
