Summary: This lens advertisement states that it has USM that allows it to have a smaller size but if you go to the canon site and compare this lens with the Canon EF 75-300 III USM version you will find "The optical system, construction, and exterior are the same as the EF 75-300 mm f/4-5.6 III USM's. The difference is that it uses a DC motor instead of a USM to drive the AF".
Summary: As far as lenses go I'm not an expert by any means. But I would say if you can afford $100 for a lens then these are pretty good. But I would recommend saving up or footing the bill for a more expensive one, as you get good shots with this, but I think they could be better. I have a T2i and the shots I get from this are decent, but I have a feeling could be a lot better with a higher quality lens. It's good for the price.
Summary: Let's go back about two years ago......I was a junior in college and I had some extra spending money in my pocket. I pondered on what new and exciting toy I should add to my collection for months. Luckily I did not jump on any big investment right away and let myself research new products coming out.
You get what you pay for, but that's not such a horrible thing.

Summary: For the price, who can resist? It offers the zoom you need at an affordable price. Yes at 300mm the optics are a little iffy and image stabilization would be a plus, but you get what you pay for. I got this lens new for $105 so I'm not one to complain about its optical performance. I get the zoom I need and I'm content. I'll find ways to work out the hand-held shakiness at 300mm by making sure I can have a fast shutter speed.
