The Fujifilm GFX100S II sensor (highlighted) drawn to scale against common formats. Its area is 167% of a full-frame sensor.

Focal length equivalents & field of view#

Multiply any focal length by 0.79 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 55 mm
f/1.2	f/0.9	66.4 m
f/1.4	f/1.1	56.9 m
f/1.8	f/1.4	44.3 m
f/2	f/1.6	39.9 m
f/2.8	f/2.2	28.5 m
f/4	f/3.2	20.0 m
f/5.6	f/4.4	14.3 m
f/8	f/6.3	10.0 m

Diffraction & pixel pitch#

With 3.76 µm pixels, diffraction starts to soften pixel-level detail around f/5.6. For maximum sharpness keep landscapes between f/3.1 and f/6; stopping down further trades detail for depth of field.

Aperture	Airy disk diameter	Spread over	At 100% view
f/2.8	3.8 µm	1.0 px	sharp
f/4	5.4 µm	1.4 px	sharp
f/5.6	7.5 µm	2.0 px	sharp
f/8	10.7 µm	2.9 px	slight softening
f/11	14.8 µm	3.9 px	visibly soft
f/16	21.5 µm	5.7 px	visibly soft
f/22	29.5 µm	7.9 px	visibly soft

Maximum print sizes#

At 102 MP the Fujifilm GFX100S II produces 11,648 × 8,736 pixel images. See the 102 megapixel guide or the print size calculator.

Resolution	Typical use	Inches	Centimetres
300 DPI	Photo-lab quality	38.8 × 29.1 in	99 × 74 cm
240 DPI	Fine-art inkjet	48.5 × 36.4 in	123 × 92 cm
200 DPI	Wall print	58.2 × 43.7 in	148 × 111 cm
150 DPI	Poster, viewed from 1 m+	77.7 × 58.2 in	197 × 148 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
18 mm (14 mm eq.)	35.2 s	9.8 s	11.7 s	14.0 s
25 mm (20 mm eq.)	25.3 s	7.0 s	8.4 s	10.1 s
30 mm (24 mm eq.)	21.1 s	5.9 s	7.0 s	8.4 s
44 mm (35 mm eq.)	14.4 s	4.0 s	4.8 s	5.7 s
63 mm (50 mm eq.)	10.0 s	2.8 s	3.3 s	4.0 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
30 mm	1/25 s	0.3 s	1.3 s
63 mm	1/50 s	1/6 s	0.6 s
127 mm	1/100 s	1/13 s	0.3 s
253 mm	1/200 s	1/25 s	1/6 s
