Sensor size compared#

The Fujifilm X-E4 sensor (highlighted) drawn to scale against common formats. Its area is 42% of a full-frame sensor, which collects about 1.2 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	f/3.1	20.1 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 3.77 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	7.8 px	visibly soft

Maximum print sizes#

At 26.1 MP the Fujifilm X-E4 produces 6,240 × 4,160 pixel images. See the 26 megapixel guide or the print size calculator.

Resolution	Typical use	Inches	Centimetres
300 DPI	Photo-lab quality	20.8 × 13.9 in	53 × 35 cm
240 DPI	Fine-art inkjet	26.0 × 17.3 in	66 × 44 cm
200 DPI	Wall print	31.2 × 20.8 in	79 × 53 cm
150 DPI	Poster, viewed from 1 m+	41.6 × 27.7 in	106 × 70 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	19.6 s	23.4 s	28.1 s
13 mm (20 mm eq.)	25.1 s	13.5 s	16.2 s	19.5 s
16 mm (25 mm eq.)	20.4 s	11.0 s	13.2 s	15.8 s
23 mm (35 mm eq.)	14.2 s	7.7 s	9.2 s	11.0 s
33 mm (51 mm eq.)	9.9 s	5.3 s	6.4 s	7.7 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
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
