Focal length equivalents & field of view#

Multiply any focal length by 1.00 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 6.25 µm pixels, diffraction starts to soften pixel-level detail around f/9.3. For maximum sharpness keep landscapes between f/5.1 and f/9; stopping down further trades detail for depth of field.

Maximum print sizes#

At 22.3 MP the Canon EOS 5D Mark III produces 5,760 × 3,840 pixel images. See the 24 megapixel guide or the print size calculator.

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 5D Mark III?

The Canon EOS 5D Mark III has a crop factor of 1.00× relative to 35 mm full frame (diagonal 43.3 mm vs 43.3 mm).

What size is the Canon EOS 5D Mark III sensor?

36.0 × 24.0 mm (Full frame (35 mm)), an area of 864 mm² — 100% of full frame.

Is the Canon EOS 5D Mark III full frame?

Yes — its sensor is the same 36 × 24 mm size as 35 mm film.

How many megapixels does the Canon EOS 5D Mark III have?

22.3 megapixels (5,760 × 3,840 pixels), enough for a 19 × 13 inch print at 300 DPI.

What lens mount does the Canon EOS 5D Mark III use?

The Canon EOS 5D Mark III uses the Canon EF (flange distance 44.00 mm).

How long can I expose the night sky with the Canon EOS 5D Mark III?

With a 20 mm lens (20 mm equivalent) the 500 rule gives 25 s and the stricter NPF rule at f/2.8 gives 14 s.
