I wonder what the analog max ISO of the K-70 is. I remember someone had posted a set of graphs (PF or DPR, not sure) comparing the ISO performance or amplification of K-1 & D810.
If I remember correctly, the pattern changed after ISO1600, which was suggested as a limit for analog amplification & after that it was all digital. Now DPR said in its review that at ISO3200 and above RAW of K-70 seems to be "baked" by some processing. It could be the same case as that of K-1 & D810.
Would like to get some clarity about this - repercussions of analog and digital amplification (If, at all that's the case), and it's effects on RAW and post-processing.
