Here is a Canon RF 24-70mm f/2.8L IS review. The Canon RF 24-70mm f/2.8L IS is one of the “holy trinity” lenses for the Canon EOS R full frame mirrorless system.
The experts at Optical Limits (formerly known as photozone.de) posted their full Canon RF 24-70mm f/2.8L IS review.
From their conclusion:
The Canon RF 24-70mm f/2.8 USM L IS is the best fast standard zoom lenses that we tested to date. However, this doesn’t mean that it’s flawless – standard zoom lenses never are. In terms of resolution, the broader center zone is superbly sharp at all relevant aperture settings. The border quality is also on a very high level. The corner quality varies a bit though. Except for the sweet spot at 50mm, the corners are a tad soft at f/2.8. However, they have recovered nicely at f/5.6 latest. These days you tend to correct the secondary characteristic via image auto-correction. However, when analyzing the raw qualities, the results reveal a couple of issues. The vignetting is rather extreme at 24mm f/2.8 for instance – and that’s despite the very large front element. Complex image distortions are also quite obvious at 24mm and there are fairly visible pincushion distortions at 70mm. Lateral CAs are quite moderate albeit not zilch. The quality of the bokeh is very good as far as general rendition is concerned but not ideal with respect to out-of-focus highlights. Read the review at Optical Limits
