Sensor size compared#

The Canon EOS 30D sensor (highlighted) drawn to scale against common formats. Its area is 39% 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 1.60 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 27 mm
f/1.2	f/1.9	32.4 m
f/1.4	f/2.2	27.8 m
f/1.8	f/2.9	21.6 m
f/2	f/3.2	19.5 m
f/2.8	f/4.5	13.9 m
f/4	f/6.4	9.75 m
f/5.6	f/9.0	6.97 m
f/8	f/12.8	4.89 m

Diffraction & pixel pitch#

With 6.42 µm pixels, diffraction starts to soften pixel-level detail around f/9.6. For maximum sharpness keep landscapes between f/5.3 and f/10; stopping down further trades detail for depth of field.

Aperture	Airy disk diameter	Spread over	At 100% view
f/2.8	3.8 µm	0.6 px	sharp
f/4	5.4 µm	0.8 px	sharp
f/5.6	7.5 µm	1.2 px	sharp
f/8	10.7 µm	1.7 px	sharp
f/11	14.8 µm	2.3 px	slight softening
f/16	21.5 µm	3.3 px	visibly soft
f/22	29.5 µm	4.6 px	visibly soft

Maximum print sizes#

At 8.2 MP the Canon EOS 30D produces 3,504 × 2,336 pixel images. See the 8 megapixel guide or the print size calculator.

Resolution	Typical use	Inches	Centimetres
300 DPI	Photo-lab quality	11.7 × 7.8 in	30 × 20 cm
240 DPI	Fine-art inkjet	14.6 × 9.7 in	37 × 25 cm
200 DPI	Wall print	17.5 × 11.7 in	45 × 30 cm
150 DPI	Poster, viewed from 1 m+	23.4 × 15.6 in	59 × 40 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.)	34.7 s	28.4 s	32.3 s	37.0 s
12 mm (19 mm eq.)	26.0 s	21.3 s	24.2 s	27.7 s
15 mm (24 mm eq.)	20.8 s	17.0 s	19.4 s	22.2 s
22 mm (35 mm eq.)	14.2 s	11.6 s	13.2 s	15.1 s
31 mm (50 mm eq.)	10.1 s	8.2 s	9.4 s	10.7 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
15 mm	1/25 s	0.3 s	1.3 s
31 mm	1/50 s	1/6 s	0.6 s
62 mm	1/100 s	1/13 s	0.3 s
125 mm	1/200 s	1/25 s	1/6 s
