All Olympus cameras used the 50mm f2 macro
The Nikons and Kodak used the Nikkor 80-200 f2.8
I had to reshoot the D300 images later on in the day, so while I didn't think there would be any influence on the small bit of daylight coming through from the studio window, well there was, as you can see parts of the D300 shadows are a little darker. Live and learn!
The '4stop' images are 100% crops of the various files which have had +4 stops of exposure compensation added in Lightroom to see what the shadow noise is like.
