This is an excellent mid level zoom lens for the enthusiast or cash strapped semi-professional who needs a decent zoom lens. I bought mine through Amazon Warehouse Deals in Like New condition for about half price, so I did really well price wise.

Good performance, decent value and excellent image stabilisation. However, it's pretty bulky and suffers from ‘zoom creep'

This is a good quality product that offers good value for money in the very short term. Although as with most products of this type, the value will deteriorate over time and should be able to get a cheaper version next year. It's a great device with plenty of features that I would highly recommend.

Good Lens

Great Lens would love a more expensive one f2 is usm ..but this is great very good lens for the money

The lens works very good when you have good light. On lower light you'll see some of the sharpness fade, its good for bright light and can't beat the price of the L lens.

the image stabiliser is the reason I bought the zoom for wildlife,works a treat...

When I purchased my 7D, I also picked this lens up for some wildlife and nature photography. With the cropped sensor, 300mm is close enough for animals that don't want to eat you... I'm impressed. Images are pretty sharp and colorful.

Image stabilized; Superior build quality; Super-sharp images

The Canon EF 70-300mm f/4-5.6 USM L IS delivers high quality results throughout the zoom range but especially at 70mm. At 300mm it is clearly better than its in-house cousins (EF 70-300mm f/4-5.6 USM IS & EF 70-300mm f/4.5-5.6 USM DO IS) reaching very good to excellent center results combined very...

I was looking for a lens that could take shots of wildlife from a distance. This lens certainly fits the bill and the IS helps in low light. I was also looking at the 100-400mm lens but the negative comments about its barrel focusing system pushed me towards this one.
