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

Handling and features Performance Verdict Specification This new entry to Canon's L-series of lenses covers the popular 24-70mm focal range. As it has a constant maximum aperture of f/4 it is available at a lower price than the latest 24-70mm f/2.8 lens and also includes image stabilisation...

Excellent sharpness throughout the range in the centre at maximum aperture; Good build quality; Relatively lightweight; Reasonably low distortion

Quite expensive for a lens with an f/4 maximum aperture; Sharpness at 24mm towards the edges of the frame falls behind performance in the centre of the frame

Announced towards the end of 2012, Canon's EF 24-70mm f/4L IS USM zoom lens provides a lighter, more affordable alternative to the EF 24-70mm f/2.8L USM, which we reviewed in April of the same year .

Ive been looking for the perfect street lens for a while. Recenlty bought a canon 6d and added the 24-105mm. Wow blown away -= wouldnt be the same on my old 60d as the 6d is full frame. Thanks Cameras Direct. As always a great experience.

I had read reviews and thought I'd like this lens but I love it. Great versatility. Really enjoying it!

I have recently upgraded to a 6D with the EF 24-70mm f/4L IS USM lens. The 6D is a wonderful camera that deserves great lenses. This lens has all the features and performance I expected and has allowed me to take my photography to a whole new level.

Superior build quality; Super-sharp images; Fast auto-focus

This is a decent lens, not as sharp as my primes but has very appealing and useful features. Actually if you just compare the 24-70 f4 to other zooms it stacks up quite nicely. It is sharper than all the other zooms I have used save my 70- 200mm f4.

My husband and I wanted to get a len that can be used when we upgrade our current camera in the near future. I have many friends who are good at pic shooting recommending this same len to use. Very nice work after We tried it, definitely love this purchase!

Clearly one of the best lenses available out there, and I'm surely not going to be the one who gives a negative review to such a great piece of equipment. If this focal length is the right one for you, then look no further and don't be afraid of buying it because it never fails to impress.

Well an L lens doesn't really need a review, having said that the product is excellent for general photography. Very well for low-light/long duration shots!
