The 36×24 mm frame. It is the reference for angle of view, so its crop factor is 1.
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
QWhat angle of view does 150 mm give on Full frame?
16.4° diagonally, 13.7° horizontally and 9.1° vertically.
QWhat is 150 mm in 35 mm terms?
150 mm — the focal length multiplied by this sensor’s crop factor of 1.
QWhat is this combination good for?
It falls in the telephoto group. Standing two metres away, it frames 0.48 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.
