Well, Gee, beta 26 was only just released and it takes time for people to do a proper evaluation. Be patient and I'm sure reports will filter in from other DCT members. As for me, I flashed the new firmware only on Sunday and have had no spare time to even think about reviewing test footage from the GC, plus I happen to be working on an unrelated matter with a different developer that has priority at the moment. And today is overcast, so it will be a while yet before I could offer any feedback anyway. Hang in there.
Edit:
@jokiin's right, firmware development when it comes to image quality is a process, not either or.
