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 50 mm	Equiv. aperture (DoF)
Full frame	50 mm · 47°	f/1.4
APS-C	75 mm · 32°	f/2.1
APS-C (Canon)	80 mm · 30°	f/2.2
Micro Four Thirds	100 mm · 24°	f/2.8

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: 50 mm f/1.4 on full frame.

Focal	Aperture	at 1 m	at 2 m	at 5 m	at 10 m	Hyperfocal	Blur @2 m
50 mm	f/1.4	3.2 cm	13.1 cm	83.7 cm	3.44 m	59.6 m	2.5%

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).
