Sensor size compared#

The Panasonic Lumix DMC-GH1 sensor (highlighted) drawn to scale against common formats. Its area is 32% of a full-frame sensor, which collects about 1.7 stops less total light at the same exposure.

Focal length equivalents & field of view#

Multiply any focal length by 1.82 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 24 mm
f/1.2	f/2.2	29.1 m
f/1.4	f/2.5	25.0 m
f/1.8	f/3.3	19.4 m
f/2	f/3.6	17.5 m
f/2.8	f/5.1	12.5 m
f/4	f/7.3	8.75 m
f/5.6	f/10.2	6.26 m
f/8	f/14.5	4.39 m

Diffraction & pixel pitch#

With 4.72 µm pixels, diffraction starts to soften pixel-level detail around f/7.0. For maximum sharpness keep landscapes between f/3.9 and f/7; stopping down further trades detail for depth of field.

Aperture	Airy disk diameter	Spread over	At 100% view
f/2.8	3.8 µm	0.8 px	sharp
f/4	5.4 µm	1.1 px	sharp
f/5.6	7.5 µm	1.6 px	sharp
f/8	10.7 µm	2.3 px	slight softening
f/11	14.8 µm	3.1 px	visibly soft
f/16	21.5 µm	4.5 px	visibly soft
f/22	29.5 µm	6.3 px	visibly soft

Maximum print sizes#

At 14 MP the Panasonic Lumix DMC-GH1 produces 4,000 × 3,000 pixel images. See the 14 megapixel guide or the print size calculator.

Resolution	Typical use	Inches	Centimetres
300 DPI	Photo-lab quality	13.3 × 10.0 in	34 × 25 cm
240 DPI	Fine-art inkjet	16.7 × 12.5 in	42 × 32 cm
200 DPI	Wall print	20.0 × 15.0 in	51 × 38 cm
150 DPI	Poster, viewed from 1 m+	26.7 × 20.0 in	68 × 51 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
8 mm (15 mm eq.)	34.4 s	25.6 s	30.0 s	35.2 s
11 mm (20 mm eq.)	25.0 s	18.6 s	21.8 s	25.6 s
13 mm (24 mm eq.)	21.2 s	15.7 s	18.4 s	21.7 s
19 mm (35 mm eq.)	14.5 s	10.8 s	12.6 s	14.8 s
28 mm (51 mm eq.)	9.8 s	7.3 s	8.6 s	10.1 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
13 mm	1/25 s	0.3 s	1.3 s
28 mm	1/50 s	1/6 s	0.6 s
55 mm	1/100 s	1/13 s	0.3 s
110 mm	1/200 s	1/25 s	1/6 s
