फोकल-दूरी इसके अंग्रेजी अर्थ का उदाहरण

The combination of on-lens aperture control and the generous 'flange focal distance' make OM lenses adaptable (with limited functionality) to a variety of other camera systems – including Canon EOS models – by using a mount-specific adapter.

Typically, camera bodies with shorter flange focal distance can be adapted more readily to lenses with longer flange focal distance.

Flange focal distance is one of the most important variables in a system camera, as lens seating errors of as little as 0.

Any discrepancies between eye focus and measured focus that manifest them"shy;selves across a range of distances within a single lens may be collimation error with the lens, but if such discrepancies occur across several lenses, it is more likely to be the flange focal distance or the ground glass (or both) that are misset.

Due to research on optimal flange focal distance settings, it is currently considered better for flange focal distance to be set to somewhere within the film's emulsion layer, rather than on the surface of it.

On bodies with a flange focal distance greater than that of M42, most notably Nikon, three options are available.

Flange focal distance: 45.

They also kept the same flange focal distance (also called registration distance or register) as the M42 screw-mount, so that M42 lenses focus correctly using the correct adapter (such as Pentax original or Bower).

There are however other third-party adapters that add to the flange focal distance so that one loses the ability to focus to infinity.

K-mount cameras have a suitable flange focal distance (45.

Other SLRs with a short flange-focal distance can accept M42 lenses as well: Canon EF-mount (44.
