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.

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...

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.

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

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

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

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

Using it so far for two weeks. I don't regret this purchase

Well built lens, which I am currently using on a Canon 7D Mark 2 so I am not really getting the wide angle benefit at this time. The photos are very sharp and I intend to upgrade to the Canon 5D Mark 4 to fully appreciate the lens.

Pro photographer in Atlanta...used the 2.8 24-70 until a recent trip to Rome where the intention was to use only one lens (landscapes, building, museums, artwork, etc.) with all the walking..70mm is slightly too short, so bought and used the 24-105. Worked perfectly. No low light problems.
