Setting backfocus with beamer (16x5.5 lens)
Hi all,
We recently used a 720p beamer via component to set the backfocus, as no monitor was at hand. We didn't manage a sharp image at both focal ends !! Is that because the image on the beamer is too large ( but same resolution as the Panasonic monitor we usually have) or because our stock lens is actually deficient ? We used the Siemens chart from the lens manual. Thanks ! |
