    Thanks for the link, David.
    I think ISO6400 is pretty good, but ISO12800 seems so-so.

    Kind regards.

    Robin Wong also has some real world examples here :
    Robin Wong: Olympus OM-D E-M5 Review: Bukit Bintang Night Shooting

    Both examples are out of camera jpegs (or Olympus Viewer derived jpegs) with 'default' jpeg parameters of contrast, sharpening, saturation set to 0... with NR off or low.

    You should be aware that setting contrast, sharpening and saturation to -2 with 'muted' colour... outputting in AdobeRGB to tiff and finishing in Lightroom will give cleaner detailed images.

    When LR 4 supports the E-M5 we can expect much better IQ (better highlight recovery, better noise reduction, better sharpening).

    These results from Olympus Viewer - effectively what you can get out of camera - are pretty impressive.

    Cheers

    This is interesting...

    Vergleich: DSLR ber 1.000 Euro im Test - CHIP Online

    Especially the Dynamic Range at base ISO - lots of angst over on dpreview about this.

    Cheers

    Brian, I can't help thinking some of the figures at Chip Online are very strange. Nice reading for anyone interested in the OM-D (as I am) but hardly the whole truth. What do you think?

    I take the numbers with a huge dose of salt... no sign of the test methodology behind these numbers. Will wait to get a hold of one for myself, or until dpreview crawl all over theirs (just received today, apparently).

    I've seen a whole range of samples on the web, from very impressive to atrocious... it's amazing how easily a bad exposure can ruin an image. I'm taking more care these days to get exposure spot on, following Pekka Potka's method here :
    pekkapotka - Journal - Expose to the right, ETTR - with*E-P3

    The flashing highlights in live view are a godsend.

    Cheers

    I had a second look. In the 5DMkII row I found the battery will last for 1190 images if you use the flash, and for 1930 images without the flash. Hmm, I don't recall any flash on my 5D or 5DMkII. Did I miss that feature... ?

    We can probably just leave the table altogether for now.

    Pekka has supported us with some good reading of lately. I agree the flashing highlights are great. For the ETTR method I wonder a little about his method leaving the WB to Auto. My experience is that in-camera histograms usually answers better to the raw histograms if the WB is left somewhere between 5500 and 6000K.

    As usual, and in line with what you say, we all need to try the camera and measure it against our own personal needs.

    Re: Olympus OM-D E-M5 Low Light ISO samples

    Riley, Yes and no. I was not sure until I tried the GH-2 vs the old G1. The GH-2, despite the higher pixel density, is clearly at least 2 stops better and is just so much better overall when it comes to IQ (vs the G1).

    With the EM-5, I expect about the same performance as the GH-2 (not less) and that appears to be the case.

    Coupled with that, the 5 axes stabilizer + grips, it is looking fabulous, overall.

    Nothing earth shaking wrt to sensor performance but not a let down either.

    well I think I will be sliding towards GH2 myself
    really what I need it for is video, 30 fps isnt going to cut it
    be interesting to experiment with everything else

    Re: Olympus OM-D E-M5 Low Light ISO samples

    I'm impressed by what appears to be the fact they've eliminated the annoying yellow blotching that started to show up around 1600 ISO in previous cameras. Strictly speaking, there are 4 kinds of visible noise in 4/3rd images:
    1. Coloured speckles.
    2. Luminance noise.
    3. Yellow blotching (covers larger areas)
    4. Blue blotching and banding.
