PM2: Olympus 75mm lens at f/2.5, two exposures, one near-equivalent to the D800 shot, the other as I would normally have exposed it to give a similar raw histogram (+2/3 stop), i.e. shutter speeds of 1/180 and 1/125s.

Should be the same shutter speeds.

It is not clear what you mean by that phrase.

1/200th and 1/180th are surely close enough given the other uncertainties.  The significantly different exposure at 1/125th also represents a perfectly reasonable alternative choice, given how sensor saturation and ISO-setting scale factor were set on the PM2.  When I use the cameras I normally expose this way (i,e. relative to saturation level), though as I said not at ISO1600.


The 1/180 and 1/200 "equivalent" exposures don't look very equivalent. The D800 shot looks awful.

Would you mind shooting a few more images.

Using exactly the same shutter speed settings (so people can't complain) and equivalent ISO and aperture, shoot the OM-D at 1600 and the D800 at 3200 and 6400.

Then possibly post the full pictures, rather than just crops?'s gear's gear list
