I use the lens on my 5d MkIII and there is a noticeable difference between it and my Tamron equivalent that I'd been using for 3 years. The Tamron 24x70 has stabilization and I still get better results with this Canon lens in comparison.

Stunning detail and as sharp as my 16-35 f4 IS USM. Good for portraits with wide f2.8 aperture, so get out of focus background. I'll probably miss it not having IS as I like to push the limits - just need to remind myself of the old days, before IS.

I suppose the IS is not needed in a wider lens due to the focal length, but I can see it being useful at 70mm.

Typical canon sharpness build quality and reliability; I have all canon glass and this purchase recently is one of the few lenses I didnt have to bridge the gap between the ultra wide and the super long stuff

No IS

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...
