Yes I can understand that, Nikon also does the same with D-Lightning. So with RAW+JPEG on, I experienced same with Nikon D90 and even more with D5100. So if you are setting RAW+JPEG in Oly OMD you will get the same, as same exposure will be applied on both formats. However when taking in RAW mode only this shouldn't be a problem. DPReview compare photos in RAW and high ISO too, why they didn't noticed difference in exposure? http://www.dpreview.com/reviews/olympusem5/21
I will raise the concern in DPR forum too.
I can understand the excuse for pushing up in SLT cameras, but in m43?
Also where its mentioned in DXOMark website, what testing procedure they are using? As I can't find it. It should be mentioned somewhere that they use caliberated ISOs and not factory default one!
But then I also noticed, DXO never tested Fuji EXR modes properly, they always tested on standard mode, never in hardware DR-priority mode! Even a few times I requested here to retest the cameras in DR mode too, even if it cost drop in resolution, as for many of us its not an issue, but lower DR is!
