Canon EOS IX

The Canon EOS IX is a film slr from 1996 that exposes a 30 × 17 mm frame on APS film (H). Its crop factor is 1.25×, so a 50 mm lens frames like 63 mm on full frame. Every number below is calculated for this exact film format.

Focal length equivalents & field of view#

Multiply any focal length by 1.25 to get the full-frame field of view. Angles are for a rectilinear lens focused at infinity.

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.)

11 mm (14 mm eq.)36.3 s
16 mm (20 mm eq.)24.9 s
19 mm (24 mm eq.)21.0 s

40 mm (50 mm eq.)10.0 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.

Frequently asked questions#

What is the crop factor of the Canon EOS IX?

The Canon EOS IX has a crop factor of 1.25× relative to 35 mm full frame (diagonal 34.5 mm vs 43.3 mm).

What size is the Canon EOS IX frame?

30.2 × 16.7 mm (APS film (H)), an area of 504 mm² — 58% of full frame.

What lens mount does the Canon EOS IX use?

The Canon EOS IX uses the Canon EF (flange distance 44.00 mm).

How long can I expose the night sky with the Canon EOS IX?

With a 16 mm lens (20 mm equivalent) the 500 rule gives 25 s.
