Focal length equivalents & field of view#

Multiply any focal length by 1.01 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	51.7 m
f/1.4	f/1.4	44.4 m
f/1.8	f/1.8	34.5 m
f/2	f/2.0	31.1 m
f/2.8	f/2.8	22.2 m
f/4	f/4.0	15.6 m
f/5.6	f/5.6	11.1 m
f/8	f/8.1	7.80 m

Diffraction & pixel pitch#

With 8.81 µm pixels, diffraction starts to soften pixel-level detail around f/13.1. For maximum sharpness keep landscapes between f/7.2 and f/13; stopping down further trades detail for depth of field.

Aperture	Airy disk diameter	Spread over	At 100% view
f/2.8	3.8 µm	0.4 px	sharp
f/4	5.4 µm	0.6 px	sharp
f/5.6	7.5 µm	0.9 px	sharp
f/8	10.7 µm	1.2 px	sharp
f/11	14.8 µm	1.7 px	sharp
f/16	21.5 µm	2.4 px	slight softening
f/22	29.5 µm	3.4 px	visibly soft

Maximum print sizes#

At 11.1 MP the Canon EOS-1Ds produces 4,064 × 2,704 pixel images. See the 12 megapixel guide or the print size calculator.

Resolution	Typical use	Inches	Centimetres
300 DPI	Photo-lab quality	13.5 × 9.0 in	34 × 23 cm
240 DPI	Fine-art inkjet	16.9 × 11.3 in	43 × 29 cm
200 DPI	Wall print	20.3 × 13.5 in	52 × 34 cm
150 DPI	Poster, viewed from 1 m+	27.1 × 18.0 in	69 × 46 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.)	35.5 s	23.4 s	25.9 s	28.9 s
20 mm (20 mm eq.)	24.8 s	16.4 s	18.1 s	20.2 s
24 mm (24 mm eq.)	20.7 s	13.6 s	15.1 s	16.8 s
35 mm (35 mm eq.)	14.2 s	9.4 s	10.4 s	11.6 s
50 mm (50 mm eq.)	9.9 s	6.5 s	7.2 s	8.1 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
99 mm	1/100 s	1/13 s	0.3 s
199 mm	1/200 s	1/25 s	1/6 s
