Canon EOS 450D

The Canon EOS 450D is a DSLR from 2008 with a APS-C (Canon) sensor measuring 22.2 × 14.8 mm and 12.2 megapixels. Its crop factor is 1.62×, so a 50 mm lens frames like 81 mm on full frame. Every number below is calculated for this exact sensor.

The Canon EOS 450D sensor (highlighted) drawn to scale against common formats. Its area is 38% of a full-frame sensor, which collects about 1.4 stops less total light at the same exposure.

Focal length equivalents & field of view#

Multiply any focal length by 1.62 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.

Diffraction & pixel pitch#

With 5.20 µm pixels, diffraction starts to soften pixel-level detail around f/7.7. For maximum sharpness keep landscapes between f/4.3 and f/8; stopping down further trades detail for depth of field.

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.

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 450D?

The Canon EOS 450D has a crop factor of 1.62× relative to 35 mm full frame (diagonal 26.7 mm vs 43.3 mm).

What size is the Canon EOS 450D sensor?

22.2 × 14.8 mm (APS-C (Canon)), an area of 329 mm² — 38% of full frame.

Is the Canon EOS 450D full frame?

No — its sensor is APS-C (Canon), which is 2.6× smaller in area than full frame.

How many megapixels does the Canon EOS 450D have?

12.2 megapixels (4,272 × 2,848 pixels), enough for a 14 × 9 inch print at 300 DPI.

What lens mount does the Canon EOS 450D use?

The Canon EOS 450D uses the Canon EF-S (flange distance 44.00 mm).

How long can I expose the night sky with the Canon EOS 450D?

With a 12 mm lens (19 mm equivalent) the 500 rule gives 26 s and the stricter NPF rule at f/2.8 gives 21 s.
