Equivalent focal length on different cameras#

Field of view and depth-of-field equivalence when this lens is used on bodies with different sensor sizes (natively or via an adapter).

Camera format	At 35 mm	Equiv. aperture (DoF)
Full frame	35 mm · 63°	f/1.8
APS-C	52 mm · 44°	f/2.7
APS-C (Canon)	56 mm · 42°	f/2.9
Micro Four Thirds	70 mm · 34°	f/3.6

Depth of field & background blur#

Computed on its native Full frame format (CoC 30 µm). “Blur @2 m” is the size of an out-of-focus point at infinity, as a percentage of frame width, with the subject at 2 m — a simple bokeh index. Full table: 35 mm f/1.8 on full frame.

Focal	Aperture	at 1 m	at 2 m	at 5 m	at 10 m	Hyperfocal	Blur @2 m
35 mm	f/1.8	8.5 cm	34.9 cm	2.30 m	10.9 m	22.7 m	1.0%
35 mm	f/4	19.1 cm	80.0 cm	6.37 m	414 m	10.2 m	0.4%
35 mm	f/8	39.2 cm	1.81 m	181 m	∞	5.14 m	0.2%

Handheld & night-sky limits#

NPF assumes typical 20–24 MP sensors (≈6 µm pixels on full frame, ≈3.9 µm on APS-C, ≈3.3 µm on Micro Four Thirds).

Body	Min. handheld shutter (longest focal)	500 rule at 35 mm	NPF at 35 mm, f/1.8
Full frame	1/40 s	14 s	7 s
APS-C	1/50 s	10 s	5 s
APS-C (Canon)	1/60 s	9 s	5 s
