Sensor size compared#

The Canon EOS C300 sensor (highlighted) drawn to scale against common formats. Its area is 39% of a full-frame sensor, which collects about 1.3 stops less total light at the same exposure.

Focal length equivalents & field of view#

Multiply any focal length by 1.53 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 28 mm
f/1.2	f/1.8	33.4 m
f/1.4	f/2.1	28.7 m
f/1.8	f/2.8	22.3 m

f/2.8	f/4.3	14.3 m
f/4	f/6.1	10.0 m
f/5.6	f/8.6	7.19 m
f/8	f/12.3	5.04 m

Diffraction & pixel pitch#

With 12.81 µm pixels, diffraction starts to soften pixel-level detail around f/19.1. For maximum sharpness keep landscapes between f/10.5 and f/19; stopping down further trades detail for depth of field.

Aperture	Airy disk diameter	Spread over	At 100% view
f/2.8	3.8 µm	0.3 px	sharp
f/4	5.4 µm	0.4 px	sharp
f/5.6	7.5 µm	0.6 px	sharp
f/8	10.7 µm	0.8 px	sharp
f/11	14.8 µm	1.2 px	sharp
f/16	21.5 µm	1.7 px	sharp
f/22	29.5 µm	2.3 px	slight softening

Maximum print sizes#

At 2.1 MP the Canon EOS C300 produces 1,920 × 1,080 pixel images. See the 2 megapixel guide or the print size calculator.

Resolution	Typical use	Inches	Centimetres
300 DPI	Photo-lab quality	6.4 × 3.6 in	16 × 9 cm
240 DPI	Fine-art inkjet	8.0 × 4.5 in	20 × 11 cm
200 DPI	Wall print	9.6 × 5.4 in	24 × 14 cm
150 DPI	Poster, viewed from 1 m+	12.8 × 7.2 in	33 × 18 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
9 mm (14 mm eq.)	36.2 s	49.7 s	53.6 s	58.3 s
13 mm (20 mm eq.)	25.1 s	34.4 s	37.1 s	40.3 s
16 mm (25 mm eq.)	20.4 s	28.0 s	30.1 s	32.8 s
23 mm (35 mm eq.)	14.2 s	19.5 s	21.0 s	22.8 s
33 mm (51 mm eq.)	9.9 s	13.6 s	14.6 s	15.9 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
16 mm	1/25 s	0.3 s	1.3 s
33 mm	1/50 s	1/6 s	0.6 s
65 mm	1/100 s	1/13 s	0.3 s
130 mm	1/200 s	1/25 s	1/6 s
