This is my go-to lens. It's almost always on my 5DIII, except when I need a bit more reach. Replaced my 24-105 with this lens and love the IS (gotten sharp images up to 0.5 seconds handheld), great sharpness and color as you would expect from this lens and controlling the zoom range is less cramped...

"The Canon 24-70/4 L IS lens is an excellent lens by just about any standard. It's main (minor) failing is that it is not quite as good as the Canon 24-70/2.8 L II. By any other standard it is a great lens.

I can only imagine that SLR Gear was unlucky enough to get THREE faulty copies of this lens. Mine (used on a full frame 1-Ds ii) is almost as sharp in the corners as in the centre, even at full aperture, and does not show the terrible corner performance of the SLR gear tests.

Fairly light; practical range of focal lengths; excellent IQ; Image stabilisation; Macro mode

None really

Great all round lens shoots nice & sharp

My first L series lens and I couldn't be happier. It provides sharp, nice and contrasty images with accurate autofocus. I had originally got the Tamron 24-70mm f2.8 but wasn't happy with the autofocus or its performance compared to my other Canon zooms.

Easy to use; Build quality

theonly canon 24-70 with is

As the Canon EF 24-70mm f/4L IS USM Lens hits the streets, Canon has more 50mm prime lenses in its lineup than it has full frame general purpose zoom lenses – four vs. three. I am omitting from my count the large, heavy EF 28-300mm f/3.5-5.6L IS USM Superzoom Lens and the very-wide angle EF 17-40mm...

The Canon EF 24-70mm f/4L IS USM is a very capable but also very pricey standard zoom lens that will appeal most to wedding and reportage photographers looking for a lightweight and responsive lens.

As of now, very good value for money! Basicly same image quality as 24_70 f2.8 (from f4) smaller lighter weather dwaling. I LOVE this lens! Macro mode is very usable.
