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.

Heavy; Poor in Low Light

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...

Candids of grandchildren, or anyone in fact. Easy to carry around on Canon 5d mk 4, even though a bit weighty! Well balanced. Excellent and consistent results. Would buy from Wex again, no problem.

Size and quality

F stop of 4-5.6

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

None

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.
