Canon EF 70-300mm f/4-5.6 IS USM Lens for Canon EOS SLR Cameras

Great and powerful lens! I used it with the xsi and will with the 50d. The pics so far are ourstanding. I do think it's a little pricey but the IS system is worth it.

With this lens, I can capture very nice pictures of my kids/nephew/niece. The IS work wells. Handling is good. Bokeh is what I expected.

The only thing that I like to have is the Full-Time Manual Focus which it doesn't have.

I am using this lense on a Canon Xsi and it is truely amazing. The pictures are so sharp and clear. I could not be happier with this purchase. It is a lot of money but well worth it. I love it!!!

The lens meets my expectations. I'm disappointed with picture quality at 300mm, blurry - definately need a tripod.
I'm angry about an added charge for New York sales tax. I'm not a resident of NY. Amazon wouldn't ship the item to an APO address (which our federal government declares must be viewed as a US address); so I had it delivered to a family member in NY, then forwarded to me. I was shocked to see the previously undisclosed charge added to my bill.

Having only used the lens for a few weeks, I have not had that many opportunities to see limitations, but overall the lens seems to do all that I could have asked of it. The autofocus seems to be very fast and accurate. It is not a "l" series lens, but for the price and the focal length, it is able to capture action frames as fast as the Rebel xsi it is mounted on will cycle. I am very pleased with the performance of this lens so far and would recommend it to anyone who is looking for an affordable way to outfit their digital SLR.
