Canon New F-1

The Canon New F-1 is a film slr from 1981 that exposes a 48 × 47 mm frame on 135 film. Its crop factor is 0.64× — wider than full frame, so a 50 mm lens frames like 32 mm. Every number below is calculated for this exact film format.

Focal length equivalents & field of view#

Multiply any focal length by 0.64 to get the full-frame field of view. Angles are for a rectilinear lens focused at infinity.

Equivalent aperture#

Exposure is identical at the same f-number on any format; equivalence only describes depth of field and total light.

Night-sky exposure limits#

Longest exposure before stars trail. The NPF rule accounts for pixel pitch and is stricter than the classic 500 rule — use it for pin-sharp stars on high-resolution sensors. (NPF needs a known resolution and is omitted here.)

Focal length500 rule
22 mm (14 mm eq.)35.3 s
31 mm (20 mm eq.)25.0 s
37 mm (24 mm eq.)21.0 s

Handheld shutter speed guide#

The reciprocal rule uses the equivalent focal length. High-resolution sensors may need one stop faster than this for pixel-sharp results.
