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 33 mm	Equiv. aperture (DoF)
APS-C	50 mm · 46°	f/2.1
APS-C (Canon)	53 mm · 44°	f/2.2
Micro Four Thirds	66 mm · 36°	f/2.8

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/1.4 on aps-c.

Focal	Aperture	at 1 m	at 2 m	at 5 m	at 10 m	Hyperfocal	Blur @2 m
33 mm	f/1.4	4.9 cm	19.8 cm	1.27 m	5.35 m	39.8 m	1.7%
33 mm	f/4	14.0 cm	57.7 cm	4.09 m	29.4 m	14.0 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).
