OMD now on DPreview's studio scene comparison

Been playing around with it for about half hour. All I can say is: WOW.

Comparing RAW at various ISOs:

To my eyes, looks to be one stop better than GH2, GX1, and NEX-7, two stops better than E-P3, and only one stop worse than D800. Seriously doubt it's the same GX1/G3 sensor.

Amazing that m43 is now looking as good or better than the FF Leica M9 at ISO 800/1600.

Re: OMD now on DPreview's studio scene comparison

I dont think so either. Not because of the studio comparisons(which have been up for a while actually =P), but because of real life pictures. Iso 6400 shots look way more usable than anything I've gotten out of my G3.

Oops! Didn't know they'd been available before. I guess I'm just slow, or it's just late, or . . .

They were nested in another review, but I mentioned them over and over when there was a fleld battle here about the sensor never being able to deliver as P. Potka and Techradar said.

The comparometer was there to confirm, while trolls were imparting us the error in our ways, on the wrong assumption that the sensor could be nothing else than the GX1 one, and thus, according to them, a mediocre one.

What is now interesting is to see what this application for a patent made by Oly for the E-M5 sensor actually means:

The translation is gibberish:

Any of you a Japanese speaker?

If I understand well the denosing is hardwired. That possibly explains the stellar performance the trolls could not accept.

Wow, that is possibly one of the worst translations I've ever seen. Quite surreal trying to make sense of the translation. It does make me wonder about the difficulty of translating japanese to english.

Interesting subject though.

Perhaps Professor Alarmic can further enlighten us as to this new "denosing" technology (if not too busy whipping on girly-man trolls and practicing dwarf-tossing) ? Pinocchio could use "denosing"

EM-5 samples converted using ACR 7?

Just wondering. Were the EM-5 raw files converted using ACR 7 (beta, RC, or otherwise)? I assume that the GH2, GX1, G3, NEX 7, and NEX 5N were converted using ACR 6? If that is correct then I would expect that would make a difference.

That's were the real life steps in. I'd always prefer available lenses, functional AF and great usability over theoretically superior IQ.

This was asked (and answered before) and is a strange mystery.

The shots have been up for weeks already.
They were converted with some beta of ACR 6.7.

The strange bit is that while dpreview has access to a beta of ACR 6.7 the supposedly later release candidate of ACR 6.7 that Adobe put out for users to try does not support the E-M5, and the beta of ACR 7 in the public beta of CS6 does not support the E-M5 either.

The mystery is how come that assuming beta versions come before release candidates the ACR 6.7 beta used by dpreview supports the E-M5 whereas the later release candidate of ACR 6.7 does not.

Sorry, I forgot to mention that it comes straight from 43rumors, which is looking for a better translator.

If you look at Techradar's charts you will notice that contrary to previous models, the E-M5 is much better than the E-P3 in RAW than in Jpegs.

Truepic 6 being the same, it would point to something happening in the sensor. A built in denoising the Jpeg engine cannot improve upon?

Hi

I can confirm that the IQ and ISo is nothing less than WOW!

I don't understand - the jpeg engine operates on the raw file... so if the raw file is improved, the jpeg should build upon that improvement.

Do we know yet, how techradar converts the raw files, for DxO to analyse?

Yes I know. However Truepic 6 having been made for the 12 Mpx sensor perhaps cannot handle as well the new features of the 16 Mpx sensor.

Perhaps it even conflicts with the built in denoising, so that the latter is switched off?

That is why it is important to know better about this patent.

Biggest improvement at ISO 200

To my eyes the high ISO quality (1600 and above) is slightly higher than the GX1, but at base ISO (200) it looks much cleaner with deeper blacks, even compared to the GX1 set at ISO 160

Been playing around with it for about half hour. All I can say is: WOW.

Re: OMD now on DPreview's studio scene comparison

Even though we don't know all the variable of the DPR comparison shots here is a comparison of the shadow box after all cameras have exposure matched visually (+help from histogram). RAW conversion was done in RawTherapee with all settings neutral/off and camera color profiles disabled.

Sorry, DPR stills claims that my quota is full while it is not. So these are directly from Dropbox:

Here some higher ISO examples. Obviously the NEX-7 and D800 would exhibit less noise once sized down to the 16 mp resolution of the other cameras.

Re: OMD now on DPreview's studio scene comparison

Sorry, I only just noticed that the D800 comes with a base ISO of 50, while I used the ISO 100 file. So it's already incredible result compared to all other cameras (you can see the single threads and the back end of the black barrel) would even be better.

Re: OMD now on DPreview's studio scene comparison

Seems like ISO 50 isn't "real" though, it's exposed 1 stop brighter than the ISO 100 raw file. And just now looking over to DxOmark scores I see that this is indeed the case.
