Hi JM,
Nice shoot as usual...
I have a doubt about your x40... are you sure it is a PLAN Fluor, I never see that kind of objective.... I have a x40 fluor wich have a 0,85 NA but I don't know the x40 Plan Fluor... even a CFI one... but you have a finite system
You are right it is not a plan fluor but just a Nikon fluor 40/0,85 Cor. Nevertheless, with my periplan 10/26, the images are plan. I think that why I make this mistake.
