First and for most, thanks for taking the time to do a testing and share it.
Some thoughts.
1) You pointed the DNG standard and C1. In my experience, C1 is not very friendly with DNG format, unless you want to do some mushrooms pop experiences (that can truly act as a crazy filter by the way, and it is interesting).
2) I know I know I know...that testing is not easy, that we can hesitate to bring very high definition pics on the web, that copyrights bla bla bla...
BUT, I really would like to see on those testings high resolutions imagery. At least a couple of pics.
It is like somebody is testing high-end audio and put the volume to 0,5.
I'm also aware that it is never very rewarded, but then who is gonna do it once for a while? It is like breaking the sound barrier.
I would spread the internet with 100% files and provide the Raw link on request. At least some crops that can not be used illegally if copyrights are a concern.
This is not aimed to you particularly but to internet in general.
Okay, I stay with the goodies of your testing, at least we don't have more brick walls and familly pics. Just a bit frustrating not having bigger images or high res crops.
Fred.
