The Canon EF 24-105mm f/4L IS II USM is a solid upgrade to its predecessor, a lens with some flaws that prevented us from enthusiastically recommending it when we reviewed it. It delivers sharper results with less distortion, but still suffers from a loss of sharpness when zoomed.

Constant f/4 aperture; 4.4x zoom range; Minimal vignette; Optical image stabilization; 1:4.3 macro magnification; Solid construction; Fluorine coating

Sharpness suffers at telephoto focal lengths; Visible distortion

When Canon announced the EOS 5D Mark IV last year, it arrived on the scene at the same time as two new full-frame optics: the EF 16-35mm f/2.8L III USM, and the revamped EF 24-105mm f/4L IS II USM. Both lenses play a key role in Canon's EF full-frame lineup.

Effective four-stop image-stabilisation system; Controls vignetting better than before; Suitable for a wide variety of applications

Costs a significant sum of money to upgrade; Not the big improvement in sharpness that you might expect

Its worth the price!!! Got great shots with this lens

Good upgrade from mk1 which I had for about 6 years

Good solid construction Good image stabiliser Good optics Handy carry round focal length

Moderately heavy; but well balanced on either 5D or 7D mk2

Everyone loves the 24-105mm f/4L IS version I lens. At least it seems that way. This lens has been a significant part of a very high number of amateur, enthusiast and professional kits.

This review follows the review of the EF 24-105mm f/3.5-5.6 IS STM lens , which we published in early November 2016. While that lens was pitched at hobbyists, the EF 24-105mm f/4L IS II USM lens is a fully professional product with superior optics, a constant f/4 maximum aperture, a more solid body...

The Canon EF 24-105mm f/4L IS II USM is an excellent standard zoom lens that, as you'd perhaps expect, is much better than the 10-year-old Canon EF 24-105mm f/4L IS USM that it replaces, which incidentally is one of Canon's most popular lenses.
