Upgraded camera- Canon EOS 5D mark III high ISO sample VS EOS 50D VS Olympus EP-L2

I think I might be officially out of flying RC. 700N has repeated broken clutch liner, not clutch, but the liner. E620 lipos are bloated. Been playing and spending a bit on camera and computers. Anyway, got the 5D mark III 1 day before official launch in Singapore, 16th March.

Initial thoughts is that af is very accurate even compared to the cross type af points on the 50D. However, my EP-L2 with the 14-42mm kit lens seems to be even faster than the 5D III with canon L lenses.

Test methodology:

Canon 5D MARK III- On medium, fine JPG(8MP?), Tamron 28-75 @50mm f/6.7
Canon 50D- On medium, fine JPG(9MP?), Tamron 28-75 @35mm f/6.7
Olympus PEN EP-L2- On large full 12MP JPG, 14-42mm kit @25mm f/6.3

All full size photos were uploaded to flickr as is, out of the memory card. Whatever flickr wants to do to them, I have no control anyway. Subject is just a thermaltake heatsink fan for cpu that I just grabbed off my work table.

100% Crop is done by DPP 100% crop 700pixelx700pixel, saved with JPG picture quality of 7.

Metering, white balance, NR etc etc etc, were all done in camera on auto. Of course, there will be so much inconsistency and uncontrollable variables in the test. Honestly, I wasn't expecting too much difference considering that the EP-L2 has very powerful in camera post processing. The post processing is so good that comparing the RAW with JPG, I thought the in camera post was pure magic.

Anyway here it is, ISO shootout for the 5D Mark III.

50D ISO 800


50D ISO 1600


50D ISO 3200


5D MARK 3 ISO 800


5D MARK 3 ISO 1600


5D MARK 3 ISO 6400


EPL2 ISO 800


EPL2 ISO1600


EPL2 ISO3200


Honestly, there isn't much difference at web size. Larger sample can be viewed at the flickr page...there is no ISO 3200 sample for the 5D3 because I thought it might be a piece of cake for it...NO actually that is just a more elegant way of saying I forgot to shoot at ISO 3200 for the 5D III.
