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 45 mm	Equiv. aperture (DoF)
APS-C	68 mm · 35°	f/4.2
APS-C (Canon)	72 mm · 33°	f/4.5
Micro Four Thirds	90 mm · 27°	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: 50 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
45 mm	f/2.8	5.2 cm	21.2 cm	1.36 m	5.80 m	37.0 m	1.6%
45 mm	f/4	7.4 cm	30.4 cm	1.99 m	9.03 m	25.9 m	1.1%
45 mm	f/8	14.8 cm	61.8 cm	4.49 m	37.7 m	13.0 m	0.6%

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 45 mm	NPF at 45 mm, f/2.8
