full-frame

Full-frame is typically used to denote a sensor size equalling the size of 36×24 mm (type 135) film.

Full-frame thus leads to an aspect ratio of 3:2, and a crop factor of 1.0. Full-frame is poised between crop-factor formats (such as APC-H, APS-C and FourThirds) on one hand and medium format on the other.

JAPB is a website centred on photography and photo gear, with a special interest in using old lenses on modern cameras.

We (currently, I) are not trying to push you to buying new, expensive gear. Instead, our approach is the opposite (in all aspects). Instead we want to help you made informed decisions, and if we can be said to ‘push’ anything, that would be relatively cheap, old gear.

JAPB is non-profit, in fact this is a loss generator. Some day that might change, but we’ll make sure that does not happen at the expense of the audience.
