Yes, these JPEGs look definitely better than those from GRDII (as of noise performance). But still, the noise reduction seems to be too strong for my taste and I guess also for taste of many GRDI followers? But it's pretty evident the noise performance is significantly improved. So I guess the noise level in RAW will be a very nice surprise. With GRDII, my main ISO sensitivity for indoor shots was ISO400. But I see a lot of use for GRDIII at ISO800
Can't wait to see the RAW files.
