A 17.3×13 mm frame with a crop factor of 2 — just double the focal length to read it.
Pulls distant things closer, compresses the background and blurs it, which flatters portraits.
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 105 mm give on Micro Four Thirds?
11.8° diagonally, 9.4° horizontally and 7.1° vertically.
Q. What is 105 mm in 35 mm terms?
210 mm — the focal length multiplied by this sensor’s crop factor of 2.
Q. What is this combination good for?
It falls in the telephoto group. Standing two metres away, it frames 0.33 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.
