The 24.89×18.66 mm frame used in cinema, with a crop factor near 1.4.

For tight interiors and landscapes. Step close and whatever is in front looms large.

Same field of view elsewhere

A different sensor needs a different focal length to frame the same scene.

How to read this

  • Focal length alone does not fix the angle of view — the same 50 mm sees less on a smaller sensor.
  • The crop factor is the sensor diagonal divided into the 35 mm diagonal; multiply the focal length by it for the equivalent.
  • Longer lenses magnify shake. Handheld, a shutter speed faster than one over the equivalent focal length is the usual rule.
  • A wider angle is not purely more scene: the edges stretch, so faces belong near the middle.
