Sensor size compared#

The Nikon Coolpix 990 sensor (highlighted) drawn to scale against common formats. Its area is 4% of a full-frame sensor, which collects about 4.5 stops less total light at the same exposure.

Focal length equivalents & field of view#

Multiply any focal length by 4.84 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.

Aperture on this camera	Full-frame equivalent (depth of field)	Hyperfocal at 9 mm
f/1.2	f/5.8	10.9 m
f/1.4	f/6.8	9.35 m
f/1.8	f/8.7	7.27 m
f/2	f/9.7	6.55 m
f/2.8	f/13.6	4.68 m
f/4	f/19.4	3.28 m
f/5.6	f/27.1	2.34 m
f/8	f/38.7	1.64 m

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 length	500 rule
4 mm (19 mm eq.)	25.8 s
5 mm (24 mm eq.)	20.7 s
6 mm (29 mm eq.)	17.2 s
7 mm (34 mm eq.)	14.8 s
10 mm (48 mm eq.)	10.3 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.

Focal length	No stabilisation (1/equiv. focal)	With 3-stop IS	With 5-stop IBIS
5 mm	1/25 s	0.3 s	1.3 s
10 mm	1/50 s	1/6 s	0.6 s
21 mm	1/100 s	1/13 s	0.3 s
41 mm	1/200 s	1/25 s	1/6 s

Lens#

The Nikon Coolpix 990 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 × 4.84.
