Sensor size compared#

The Sony FX30 frame (highlighted) drawn to scale against common formats. Its area is 42% of a full-frame sensor, which collects about 1.3 stops less total light at the same exposure.

Focal length equivalents & field of view#

Multiply any focal length by 1.55 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/1.9	33.7 m
f/1.4	f/2.2	28.9 m
f/1.8	f/2.8	22.5 m
f/2	f/3.1	20.2 m
f/2.8	f/4.3	14.5 m
f/4	f/6.2	10.1 m
f/5.6	f/8.7	7.24 m
f/8	f/12.4	5.08 m

Diffraction & pixel pitch#

With 3.73 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	slight softening
f/8	10.7 µm	2.9 px	slight softening
f/11	14.8 µm	4.0 px	visibly soft
f/16	21.5 µm	5.8 px	visibly soft
f/22	29.5 µm	7.9 px	visibly soft

Maximum print sizes#

At 26 MP the Sony FX30 produces 6,252 × 4,159 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	26.1 × 17.3 in	66 × 44 cm
200 DPI	Wall print	31.3 × 20.8 in	79 × 53 cm
150 DPI	Poster, viewed from 1 m+	41.7 × 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.)	35.9 s	19.4 s	23.3 s	28.0 s
13 mm (20 mm eq.)	24.9 s	13.4 s	16.1 s	19.4 s
16 mm (25 mm eq.)	20.2 s	10.9 s	13.1 s	15.7 s
23 mm (36 mm eq.)	14.1 s	7.6 s	9.1 s	10.9 s
32 mm (49 mm eq.)	10.1 s	5.5 s	6.6 s	7.9 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
32 mm	1/50 s	1/6 s	0.6 s
65 mm	1/100 s	1/13 s	0.3 s
129 mm	1/200 s	1/25 s	1/6 s
