Sensor size compared#

The Canon EOS RP sensor (highlighted) drawn to scale against common formats. Its area is 100% of a full-frame sensor.

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.

Aperture on this camera	Full-frame equivalent (depth of field)	Hyperfocal at 43 mm
f/1.2	f/1.2	51.4 m
f/1.4	f/1.4	44.1 m
f/1.8	f/1.8	34.3 m
f/2	f/2.0	30.9 m
f/2.8	f/2.8	22.1 m
f/4	f/4.0	15.5 m
f/5.6	f/5.6	11.0 m
f/8	f/8.0	7.75 m

Diffraction & pixel pitch#

With 5.77 µm pixels, diffraction starts to soften pixel-level detail around f/8.6. For maximum sharpness keep landscapes between f/4.7 and f/9; stopping down further trades detail for depth of field.

Aperture	Airy disk diameter	Spread over	At 100% view
f/2.8	3.8 µm	0.7 px	sharp
f/4	5.4 µm	0.9 px	sharp
f/5.6	7.5 µm	1.3 px	sharp
f/8	10.7 µm	1.9 px	sharp
f/11	14.8 µm	2.6 px	slight softening
f/16	21.5 µm	3.7 px	visibly soft
f/22	29.5 µm	5.1 px	visibly soft

Maximum print sizes#

At 26.2 MP the Canon EOS RP produces 6,240 × 4,160 pixel images. See the 26 megapixel guide or the print size calculator.

Resolution	Typical use	Inches	Centimetres
300 DPI	Photo-lab quality	20.8 × 13.9 in	53 × 35 cm
240 DPI	Fine-art inkjet	26.0 × 17.3 in	66 × 44 cm
200 DPI	Wall print	31.2 × 20.8 in	79 × 53 cm
150 DPI	Poster, viewed from 1 m+	41.6 × 27.7 in	106 × 70 cm

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.

Focal length	500 rule	NPF f/1.8	NPF f/2.8	NPF f/4
14 mm (14 mm eq.)	35.7 s	16.9 s	19.4 s	22.4 s
20 mm (20 mm eq.)	25.0 s	11.8 s	13.6 s	15.7 s
24 mm (24 mm eq.)	20.8 s	9.8 s	11.3 s	13.0 s
35 mm (35 mm eq.)	14.3 s	6.7 s	7.7 s	8.9 s
50 mm (50 mm eq.)	10.0 s	4.7 s	5.4 s	6.3 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.

Focal length	No stabilisation (1/equiv. focal)	With 3-stop IS	With 5-stop IBIS
24 mm	1/25 s	0.3 s	1.3 s
50 mm	1/50 s	1/6 s	0.6 s
100 mm	1/100 s	1/13 s	0.3 s
200 mm	1/200 s	1/25 s	1/6 s

Frequently asked questions#

What is the crop factor of the Canon EOS RP?

The Canon EOS RP 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 RP sensor?

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

Is the Canon EOS RP full frame?

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

How many megapixels does the Canon EOS RP have?

26.2 megapixels (6,240 × 4,160 pixels), enough for a 21 × 14 inch print at 300 DPI.

What lens mount does the Canon EOS RP use?

The Canon EOS RP uses the Canon RF (flange distance 20.00 mm).

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

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.
