Actually, i do believe that there is some NR done when you shoot in mRaw.
The camera is a FF at 22mp so only at 22mp is the RAW untouched..once you shoot mRAW at 10mp, the camera will downsize the image and when doing this, i believe some NR is applied.
Give it a try, shoot the same image at RAW and mRAW at a high ISO like 6400 or 12800 and you will notice that the mRAW is alot cleaner than the RAW file but not as sharpâ¦similar to what happens when you apply NR on jpg.
At least that is what i foundâ¦i almost ALWAYS shoot in mRAW until i found out about this phenomenon by chance one day and now i've since reverted back to shooting full RAW and apply NR in PP⦠And no, i don't want to turn OFF NR becaue i also shoot Jpg at the same time and it's a hassle to keep turning the NR on and off..sure forget..
