I did some quick comparisons between the A77 and my MFDB and was surprised to see noise at ISO100 (on the A77). I might not have appreciated it without something "pure" to compare to.
Granted, it was JPG and DRO, so I need to redo it with RAW and perhaps ISO50.
But I was wondering if anyone had done this with an A850/A900. I would expect results in-between? Anyone in Silicon Valley want to loan me their camera?
At the same time, the noise was quite pleasing...as it is all the way up to ISO 3200. Analogously, the A77 is like shooting ISO200 C-41 vs the MFDB is like shooting ISO50 E-6.
