The 36×24 mm frame. It is the reference for angle of view, so its crop factor is 1.
Fits a great deal into one frame; edges stretch, so keep people away from the corners.
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.
Frequently asked questions
Q. What angle of view does 12 mm give on Full frame?
122° diagonally, 112.6° horizontally and 90° vertically.
Q. What is 12 mm in 35 mm terms?
12 mm — the focal length multiplied by this sensor’s crop factor of 1.
Q. What is this combination good for?
It falls in the ultra-wide group. Standing two metres away, it frames 6 metres across.
Q. How do I get the same framing on another camera?
A different sensor needs a different focal length; the equivalent combinations are listed further down this page.
