Originally posted by normhead If it doesn't affect raws, my one reason for buying the K-1ii just evaporated.
For the record, I think what people above have been suggesting is that NR is being applied to the raws, thus making them not actually raw, but partly cooked.
For me, if the accelerator unit is just improving high iso performance, then excellent. If OTOH it is doing a little bit of cooking---well, if it's not obnoxious then I'm ok with that and would find it useful. Based on what I have seen, there's a decent improvement however it's happening, enough to convince me to get the conversion.
Again, a few years ago DPR provided pretty compelling evidence that NR was being applied by Canon and Nikon for higher iso's, but as I recall it was decently done (except for the fact that they weren't honest about it).
