Focal length equivalents & field of view#

Multiply any focal length by 5.28 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 (21 mm eq.)23.7 s
5 mm (26 mm eq.)18.9 s
6 mm (32 mm eq.)15.8 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 Pro90 IS 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 × 5.28.

Frequently asked questions#

What is the crop factor of the Canon PowerShot Pro90 IS?

The Canon PowerShot Pro90 IS has a crop factor of 5.28× relative to 35 mm full frame (diagonal 8.2 mm vs 43.3 mm).

What size is the Canon PowerShot Pro90 IS sensor?

7.1 × 4.1 mm (7.1 × 4.1 mm), an area of 29 mm² — 3% of full frame.

Is the Canon PowerShot Pro90 IS full frame?

No — its sensor is 7.1 × 4.1 mm, which is 29.9× smaller in area than full frame.

How long can I expose the night sky with the Canon PowerShot Pro90 IS?

With a 5 mm lens (26 mm equivalent) the 500 rule gives 19 s.
