The Canon EF 24-70mm f/4L IS USM ($1,499 list) is a wide-to-short telephoto zoom lens for Canon cameras . It's noticeably smaller than the EF 24-70mm f/2.8L II USM, a lens that captures twice the light at its widest aperture, but lacks image stabilization and is priced around $2,300.

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...

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

This lens is great for portraits and group images. It takes great pictures and is light enough use for hours. I am very happy with this lens, it could pass as brand new.

The image quality is not that bad but I prefer F2.8 if you can pay for it.

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.

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 .

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.

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.
