Verdict

Let's be honest - the Canon EF 24-105mm f/4 USM L IS (mk I) was not the greatest lens Canon ever produced. Unfortunately neither is the Canon EF 24-105mm f/4 USM L IS II. While there are differences on detail level, the performance is roughly similar which is a little depressing given all the years that passed by since the mk I was designed. 50 megapixels are a torture ground for all lenses but it's too much for the Canon EF 24-105mm f/4 USM L IS II really. The center quality is sufficient but the corner quality just isn't there at the extreme ends. The amount of CAs is acceptable. The lens performs, of course, much better on 21 megapixel cameras with very decent results from f/5.6 at least. However, you have to live with the outlook that the glory ends once you decide to upgrade you camera. The amount of vignetting is average for this kind of lens thus there's quite some light-falloff at 24mm f/4. However, stopping down to f/5.6 resolves most of the issue already. Barrel distortions are also obvious at 24mm albeit not extreme. The lens is also no distortion wonder at 105mm. The quality of the bokeh is comparatively decent for a standard zoom lens at least.

The build quality of the Canon EF 24-105mm f/4 USM L IS II is much more convincing. The high quality materials, tight tolerances and weather sealing are certainly good enough for professional use. The USM AF is extremely fast and silent. However, if you decide to invest into this lens make sure that the AF is properly calibrated. We tested two samples and both suffered from substantial back-focusing (to a degree that we haven't seen before). The image stabilizer with its potential gain of up to 4 f-stops is a major improvement over the old lens.

So what's the final conclusion ? Honestly, we would recommend to skip this lens. We just didn't find any substantial improvement over the already not-so-great predecessor. Instead we would suggest to check out the Canon EF 24-70mm f/4 USM L IS or the Sigma 24-105mm f/4 HSM ART.
