Thanks for the work and posting. My only comment is this--I really think you need to 'change' the comparisons...its a little apples vs oranges. We really need to see 'similiar' photos... If you were assigned to shoot a 'bed' you wouldn't shoot it with a 200 DX and then shoot it with a 200 FX--you get two totally different pictures..and that effects lighting, shadow metering etc Leave the settings equal but you need to take into account the 1.5 factor of DX.
You need to get the 'perspective' equal so you are seeing the 'same' object. 70dx- 105fx etc
Again--THANKS for the work and time your putting into this!
