f-numbers

I captured the aperture ring of my Vivitar 90mm f/2.8 macro by using another "Frankenstein" setup:

- my beloved Pentax Macro Takumar SMC 50mm f/4 wide open;

- a Kenko Teleplus MC7 2X macro teleconverter;

- a Tilt-Shift adapter, to slightly increase the DOF on the numbers without closing the aperture.

The resulting magnification is 0.8X.

I hope that you will like the result.

Stay safe and healthy, dear friends, and have a nice Saturday evening!!! ;-)
