Best lens setting for sharpest image.

[ChipG]

Has anyone done a lens test on the stock HVX Leica lens? I need to know at what setting it is at is sharpest.

Thanks!

lens setting huh..

iris f5.6

[ChipG]

I understand not to go past f5.6 but at what mm setting is the Leica lens at it's sharpest? I have been told 6.5mm or Z24 but have not seen any test to back this up.

Anyone do any tests?

[ChipG]

Will anyone get mad if I repost this in the Tech section? Ment to the first time...My fault.

According to Barry's book (if I remember correctly) there's no measurable difference from f2.8 to f8

[ChipG]

Are you refering to the lens or the iris?

Thanks Chip

He is referring to iris, the "f" indicates f-stop.

The other term you are looking for is "focal length."

Hope that helps.

[ChipG]

Ahh, yes J.P.

At wat focal length is the Leica glass at it's shaprest?

[Dick Campbell]

you are referring to the "sweet spot" of a lens. aperture wide open shows aberrations more, closed down affects diffraction limiting, so there is a "sharpest aperture" usually about 2-3 stops from wide open.

everything I've read does not address focal length as a variable.
