Sensor size compared#

The Leica T (Typ 701) sensor (highlighted) drawn to scale against common formats. Its area is 43% 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	33.3 m
f/1.4	f/2.1	28.5 m
f/1.8	f/2.7	22.2 m
f/2	f/3.1	20.0 m
f/2.8	f/4.3	14.3 m
f/4	f/6.1	10.0 m
f/5.6	f/8.5	7.15 m
f/8	f/12.2	5.01 m

Diffraction & pixel pitch#

With 4.77 µm pixels, diffraction starts to soften pixel-level detail around f/7.1. 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	2.2 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	6.2 px	visibly soft

Maximum print sizes#

At 16 MP the Leica T (Typ 701) produces 4,944 × 3,278 pixel images. See the 16 megapixel guide or the print size calculator.

Resolution	Typical use	Inches	Centimetres
300 DPI	Photo-lab quality	16.5 × 10.9 in	42 × 28 cm
240 DPI	Fine-art inkjet	20.6 × 13.7 in	52 × 35 cm
200 DPI	Wall print	24.7 × 16.4 in	63 × 42 cm
150 DPI	Poster, viewed from 1 m+	33.0 × 21.9 in	84 × 56 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.)	36.4 s	22.9 s	26.8 s	31.5 s
13 mm (20 mm eq.)	25.2 s	15.9 s	18.6 s	21.8 s
16 mm (24 mm eq.)	20.5 s	12.9 s	15.1 s	17.7 s
23 mm (35 mm eq.)	14.2 s	9.0 s	10.5 s	12.3 s
33 mm (50 mm eq.)	9.9 s	6.2 s	7.3 s	8.6 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
66 mm	1/100 s	1/13 s	0.3 s
131 mm	1/200 s	1/25 s	1/6 s
