A 17.3×13 mm frame with a crop factor of 2 — just double the focal length to read it.
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.
Frequently asked questions
QWhat angle of view does 10 mm give on Micro Four Thirds?
94.5° diagonally, 81.7° horizontally and 66° vertically.
QWhat is 10 mm in 35 mm terms?
20 mm — the focal length multiplied by this sensor’s crop factor of 2.
QWhat is this combination good for?
It falls in the wide group. Standing two metres away, it frames 3.46 metres across.
QHow 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.
