Nikon KeyMission 80

The Nikon KeyMission 80 is an action camera from 2016 with a 1/2.3" sensor measuring 6.2 × 4.7 mm. Its crop factor is 5.58×, so a 50 mm lens frames like 279 mm on full frame. Every number below is calculated for this exact sensor.

Focal length equivalents & field of view#

Multiply any focal length by 5.58 to get the full-frame field of view. For fixed-lens cameras use the real focal length printed on the lens (e.g. “6.1–18.3 mm”), not the 35 mm equivalent.

Equivalent aperture#

Exposure is identical at the same f-number on any format; equivalence only describes depth of field and total light.

Night-sky exposure limits#

Longest exposure before stars trail. The NPF rule accounts for pixel pitch and is stricter than the classic 500 rule — use it for pin-sharp stars on high-resolution sensors. (NPF needs a known resolution and is omitted here.)

Focal length500 rule
4 mm (22 mm eq.)22.4 s
5 mm (28 mm eq.)17.9 s
6 mm (33 mm eq.)14.9 s
7 mm (39 mm eq.)12.8 s
9 mm (50 mm eq.)10.0 s

Handheld shutter speed guide#

The reciprocal rule uses the equivalent focal length. High-resolution sensors may need one stop faster than this for pixel-sharp results.

Lens#

The Nikon KeyMission 80 has a built-in, non-interchangeable lens. Use the real focal length of that lens with the tables above; its full-frame equivalent is that number × 5.58.

Frequently asked questions#

What is the crop factor of the Nikon KeyMission 80?

The Nikon KeyMission 80 has a crop factor of 5.58× relative to 35 mm full frame (diagonal 7.8 mm vs 43.3 mm).

What size is the Nikon KeyMission 80 sensor?

6.2 × 4.7 mm (1/2.3"), an area of 29 mm² — 3% of full frame.

Is the Nikon KeyMission 80 full frame?

No — its sensor is 1/2.3", which is 30.0× smaller in area than full frame.

How long can I expose the night sky with the Nikon KeyMission 80?

With a 5 mm lens (28 mm equivalent) the 500 rule gives 18 s.
