Canon PowerShot A10

The Canon PowerShot A10 is a compact with a 1/2.5" sensor measuring 5.3 × 4.0 mm. Its crop factor is 6.50×, so a 50 mm lens frames like 325 mm on full frame. Every number below is calculated for this exact sensor.

Focal length equivalents & field of view#

Multiply any focal length by 6.50 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 (26 mm eq.)19.2 s
5 mm (33 mm eq.)15.4 s
6 mm (39 mm eq.)12.8 s
7 mm (46 mm eq.)11.0 s
8 mm (52 mm eq.)9.6 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 Canon PowerShot A10 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 × 6.50.

Frequently asked questions#

What is the crop factor of the Canon PowerShot A10?

The Canon PowerShot A10 has a crop factor of 6.50× relative to 35 mm full frame (diagonal 6.7 mm vs 43.3 mm).

What size is the Canon PowerShot A10 sensor?

5.3 × 4.0 mm (1/2.5"), an area of 21 mm² — 2% of full frame.

Is the Canon PowerShot A10 full frame?

No — its sensor is 1/2.5", which is 40.6× smaller in area than full frame.

How long can I expose the night sky with the Canon PowerShot A10?

With a 5 mm lens (33 mm equivalent) the 500 rule gives 15 s.
