Sensor size compared#

The Minolta DiMage Z1 sensor (highlighted) drawn to scale against common formats. Its area is 2% of a full-frame sensor, which collects about 5.4 stops less total light at the same exposure.

Focal length equivalents & field of view#

Multiply any focal length by 6.55 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 7 mm
f/1.2	f/7.9	8.92 m
f/1.4	f/9.2	7.65 m
f/1.8	f/11.8	5.95 m
f/2	f/13.1	5.36 m
f/2.8	f/18.3	3.83 m
f/4	f/26.2	2.68 m
f/5.6	f/36.7	1.92 m
f/8	f/52.4	1.34 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 (26 mm eq.)	19.1 s
5 mm (33 mm eq.)	15.3 s
6 mm (39 mm eq.)	12.7 s
7 mm (46 mm eq.)	10.9 s
8 mm (52 mm eq.)	9.5 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
4 mm	1/25 s	0.3 s	1.3 s
8 mm	1/50 s	1/6 s	0.6 s
15 mm	1/100 s	1/13 s	0.3 s
31 mm	1/200 s	1/25 s	1/6 s

Lens#

The Minolta DiMage Z1 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 × 6.55.
