Hi Rik
I often disagree with numbers I read, too,
so I make my measurements several times on my setup with the Zeiss Resolution Test Object 3000.
These results are authoritative for me.

Re: Teleconverters in macro
Hi
I deliberately mention camera (pixel pitch 2.2µm and 4.9µm) and lens (10X/0.28 and 20X/0.42, they are my measured values!
At 5:1, 1:1 or in reducing photography it behaves differently.
Concerning teleconverters there is no simple general rule.

One of the five nymph stages of the purple fruit bug. https://up.picr.de/44244673zz.jpg www.focus-stacking.ch/B/05573_00.JPG Camera: Nikon ...
