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)
APS-C	52 mm · 44°	f/4.2
APS-C (Canon)	56 mm · 42°	f/4.5
Micro Four Thirds	70 mm · 34°	f/5.6

Depth of field & background blur#

Computed on its native APS-C format (CoC 20 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/2.8 on aps-c.

Focal	Aperture	at 1 m	at 2 m	at 5 m	at 10 m	Hyperfocal	Blur @2 m
35 mm	f/2.8	8.6 cm	35.4 cm	2.33 m	11.1 m	22.4 m	0.9%
35 mm	f/4	12.4 cm	51.0 cm	3.53 m	21.4 m	15.7 m	0.7%
35 mm	f/8	25.0 cm	1.07 m	10.6 m	∞	7.86 m	0.3%

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).
