Hi all
On 16 July 2015, Klaus from Photozone.de posted his review of the Canon EF 11-24mm f/4 L USM
http://www.photozone.de/canon_eos_ff/940-canon1124f4?start=1
The analysis outcome from testing a copy of that lens (on the 50 MP Canon EOS 5Ds R) indicates it faces a number of challenges (understandably) - particularly at 11mm:
Flare actually is quite good. No mention is made of bokeh (understandably).
Vignetting, barrel distortions and border CAs can be (mostly) corrected in post.
But sharpness can not actually be added in post. I realise that 50 MP is a new benchmark (which Klaus also clearly states in his review).
I appreciate the physical constraints and challenges of creating such a lens - and I applaud Canon for creating this lens... However I am really interested what other CR folk here think of the lens - particularly seeing the Photozone review.
Looking forward to your comments, for a useful & good thread of discussion.
(PS... there are a number of threads about this lens, e.g. announcement, and now some in use, with great photos - but I particularly wanted to receive & read people's thoughts on the lens review!)

The analysis outcome from testing a copy of that lens (on the 50 MP Canon EOS 5Ds R) indicates it faces a number of challenges (understandably) - particularly at 11mm:
- corner sharpness - not sharp at any aperture
- vignetting - very high, especially wide open 3.3 EV
- barrel distortion - high at 4.46%
- Chromatic Aberrations (border CAs) - high ~3.8 pixels
