Sensor size compared#

The Samsung EX2F sensor (highlighted) drawn to scale against common formats. Its area is 5% of a full-frame sensor, which collects about 4.3 stops less total light at the same exposure.

Focal length equivalents & field of view#

Multiply any focal length by 4.60 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/5.5	10.4 m
f/1.4	f/6.4	8.88 m
f/1.8	f/8.3	6.91 m
f/2	f/9.2	6.22 m
f/2.8	f/12.9	4.45 m
f/4	f/18.4	3.11 m
f/5.6	f/25.8	2.23 m
f/8	f/36.8	1.56 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 (18 mm eq.)	27.2 s
5 mm (23 mm eq.)	21.7 s
6 mm (28 mm eq.)	18.1 s
8 mm (37 mm eq.)	13.6 s
11 mm (51 mm eq.)	9.9 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
11 mm	1/50 s	1/6 s	0.6 s
22 mm	1/100 s	1/13 s	0.3 s
43 mm	1/200 s	1/25 s	1/6 s

Lens#

The Samsung EX2F 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 × 4.60.
