I find the GX7 to be really noisy at -5 NR (at base and high ISO) and I read somewhere at higher ISOs there is still NR in jpeg. Olympus just does a better job at preserving detail in that range. Feel free to try my settings and tweak to your preference. Those are what I settled with after several days of trying different sharpening and NR adjustments. Enjoy!
fredlong: I just took a second look at my old GF1 manual and indeed it does say the exact same thing. I ran some tests earlier and I thought I saw haloing artifacts at 0, but I wanted to see if anyone could confirm (my eyes are getting old and I don't trust them anymore). Looks like -5 is indeed "off" (or at least as off as it can be without resorting to RAW, anyway). Thanks.
Tried those settings and found the shots saturated and unnatural compared to the how the subject looked to the eye. Dunno what it is about Olympus jpeg fans but I dont get it, if I want to blow out or wow the shot raw manipulation is there, why set the camera to overlblow everything in jpeg? The GX7 has such a natural honest rendition of what it sees especially its white balance and skin tones.
It is now 2014, in general the idea of Olympus' superior Jpegs (mainly colour) comes from years past. Having used old models from both companies I really DO understand the fans since I am one of them.
(It has absolutely nothing to do with "blow out", I don't know why you mention such a thing.)
First body was GF1, and have looked at many images in here from years past, including threads comparing pana and oly jpegs. As for blow out, sorry I am not a proffesional photographer, I was referring to colours and saturation being blown out, so many pics I see in here look unnnatural as they have had their colours so blown out as to look cartoonish. Plus I dont find greens all that pleasant through early Oly bodies having experienced it. Simply my take, everyone has their own taste and opinion
