I am using 24mm, 35mm, and 60mm digitars on an ALPA 12SWA with the LEAF Aptus 22 (unitil the 75 comes in). The lenses are not focusing properly. A shim Kit came with the H1A adapter with clear instructions on use. The 35mm lens requires all shims removed ( -.03mm) to acheive focus. This causes the other two lenses to backfocus. The shim kit is meant to adjust the Digiback to the camera mount. It is assumed the lenses would all be calibrated identically before they are sold.
It appears each lens is not calibrated to the same focus point, and each may need shims in the lens mounts. Has anyone ever heard of this?
Thanks,
Eric
