Great all around high quality L Series Canon lens. Excellent image quality from wide to higher zoom. Rapid, quiet, accurate focus. Comparatively lightweight and compact for quality of lens and wide zoom range.[...] I have several other L series lenses; this one is up to the high standards of Canon.

Relatively Lightweight; Superb optics; Wide zoom range

Excelente Lente ! Ótimo vendedor ! Já tirei umas 1000 fotos ! O Estabilizador em 2 níveis funciona muito bem quanto a lente toda aberta e uma ótima opção e a trava de zoom que permite a utilização da lento como uma 70mm fixa ! Recomendo para fotografar natureza e esportes de velocidade !

I returned mine and got a higher-quality older lens off of eBay. I'm very happy that I did. This lens isn't very sharp at all but will fit the bill if you just need a lens and aren't too picky about the image quality.

The lens is amazing. The image stabilizer definatly helps clean up your shots. Also the lens can be locked at 70mm to prevent from sliding out. I was debating between this lens, and the 28-135 IS lens, but i choose this lens over it mainly for the longer zoom.

Image stabilizer; Long range; USM

Have to stand at least 5 feet away from subject to focus

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.

Consistent Output; Durable; Easily Interchangeable; Quick Focus; Rugged; Sharp Focus; Strong Construction

This is definitely a high quality lens, not as slow as it says on paper, image quality maintains high even at max zoom with lots of details. Unless you are shooting high speed events, I see no need for L lenses, this will work for me just fine, I mean, more than just fine!

One of the better Canon glass . Vastly reduces any camera shake and the pictures come out awesome due to negligable shake induced blur.. Tremendous in low light conditions and I have taken some fantasic pictures using this lens..

This lens does everything I had hoped. There is a huge difference in this lens compared to the 75-275mm. I love it.

Love using this lens. It really has increased my overall use of my DSLR. I am able to take photos from a distance and really capture a natural shot since I don't have to be close to the object. Overall I am very happy with this lens. Would recommend to any starter using a DSLR.

Durable; Fast / accurate auto-focus; Strong Construction

"In this zoom range there are many lenses to compare and it wasn't an easy decision. For me it came down to this lens or the 70-200 f/4 L IS USM and after trying both in the store I went with the 70-300 .
