Sony DSC-W15

The Sony DSC-W15 is a compact with a 1/1.7" sensor measuring 7.2 × 5.4 mm. Its crop factor is 4.80×, so a 50 mm lens frames like 240 mm on full frame. Every number below is calculated for this exact sensor.

Focal length equivalents & field of view#

Multiply any focal length by 4.80 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 (19 mm eq.)26.0 s
5 mm (24 mm eq.)20.8 s
6 mm (29 mm eq.)17.4 s
7 mm (34 mm eq.)14.9 s
10 mm (48 mm eq.)10.4 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 Sony DSC-W15 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 × 4.80.

Frequently asked questions#

What is the crop factor of the Sony DSC-W15?

The Sony DSC-W15 has a crop factor of 4.80× relative to 35 mm full frame (diagonal 9.0 mm vs 43.3 mm).

What size is the Sony DSC-W15 sensor?

7.2 × 5.4 mm (1/1.7"), an area of 39 mm² — 5% of full frame.

Is the Sony DSC-W15 full frame?

No — its sensor is 1/1.7", which is 22.2× smaller in area than full frame.

How long can I expose the night sky with the Sony DSC-W15?

With a 5 mm lens (24 mm equivalent) the 500 rule gives 21 s.
