You don't have to give me exact numbers. I'm just looking for the aperture at which center sharpness is highest.



Thanks for your time!

There are no plans to provide data for half stops. The value-add is minimal and basically non-existent outside of a lab perspective.

If you want to achieve maximal sharpness we should not talk about half-stop aperture steps but tripods.



So what tripod are you using ?
