I already have the 18-200mm Sigma DG and was really pleased with the results so purchased the 70-300mm DG. These lenses are for my Canon 300d.
I am not a professional photographer but I am very happy with this lens.
Yes the motor is a little noisy but nothing major and it does "hunt" sometimes to focus but the quality of my photographs so far have been excellent.
I did read quite a few reviews saying that the 300mm end of the zoom gave soft photos, I have not had that problem, my pictures have been sharp and I have compared them full screen on the PC.
I was very impressed with the macro and amazed at how much detail it picked up at 300mm. On the subject of macro one thing I did notice was you do need to be a fair distance from the object to get it in focus (maybe 2ft+) where my other lens is much closer --within 1ft. It also requires you to select macro with a switch on the lens, this makes the lens extend even further making it quite long.
overall I think this lens is an ideal choice for telephoto and macro work, not that heavy and gives pleasing results. Professional photographers may not agree with my comments but I would recommend it.
