If you can only have one lens this is the one. I keep it on my camera as primary. The best investment ever made.

I have enjoyed using this high quality lens. The pics look amazing and sharp. It does not have IS but has been a joy to use.

I had the same lens from a competitor off brand and had such inconsistent results, I decided to go all in on this lens. So happy I did. Worth all the money. I shoot a lot of low light, action events and have been totally happy with it.

Consistent Output; Fast / accurate auto-focus; Nice Bokeh; Strong Construction

Tough To Attach

I am a wedding photographer, so I need a really good lens for my photography. If you buy this you won't be disappointed! I can now shoot at higher iso levels without too much sharpness being lost and the image being too noisy. Colours are much better too now!

accurate focusing; sharp; good colours

none

Superb lens. Very happy with the output.

I can't say enough good things about this lens. We own two for wedding photography and they replaced a 24L, 35L and 50L after a critical 2.8 shoot-out reveal this zoom was a better performer wide open then the primes were stopped down.

Great image quality, wide open, at every focal length; Fast & accurate focus in challenging conditions

Lens hood breaks after modest professional use; I miss the 'perfect' lens hood design of its predecessor

I am using Canon lenses since 1981 and this one, the 2.8/24-70 II, is the best Canon lens I have ever used. Before I have bought it in 2014 I often had to change lenses (2.8/20-35 L or 2.8/17-35 L to 1,8/85 or 2.8/80-200 L or 24-85) but since then I use the 2.8/24-70 II) as a standard lens for my...

If I had to pick only one lense for the rest of my life, It will be this one. Its my workhorse for fashion photography and editorial work. Very versatile, I've shot fashion campaigns inside cars and move to tight portraits with the same lens

It's just a beautiful quality piece of glass; no noticeable lens distortion or aberration - expensive but you get what you pay for with Canon..

Very expensive

Regardless of brand, two f/2.8 zooms have for many years dominated professional photographers' camera bags, covering the 24-70mm and 70-200mm ranges. In Canon's case, these are both no-holds-barred lenses that are designed without compromise to meet the needs of the most demanding users.

Excellent sharpness; Build Quality

Slight colour fringing at short focal lengths
