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 32 mm	Equiv. aperture (DoF)
APS-C	48 mm · 48°	f/2.7
APS-C (Canon)	51 mm · 45°	f/2.9
Micro Four Thirds	64 mm · 37°	f/3.6

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/1.8 on aps-c.

Focal	Aperture	at 1 m	at 2 m	at 5 m	at 10 m	Hyperfocal	Blur @2 m
32 mm	f/1.8	6.7 cm	27.2 cm	1.76 m	7.77 m	29.1 m	1.2%
32 mm	f/4	14.9 cm	61.5 cm	4.43 m	36.3 m	13.1 m	0.6%
32 mm	f/8	30.2 cm	1.32 m	17.9 m	∞	6.58 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).

Body	Min. handheld shutter (longest focal)	500 rule at 32 mm	NPF at 32 mm, f/1.8

Frequently asked questions#

Is the Zeiss Touit 32mm f/1.8 full frame?

No — it is designed for APS-C sensors. On a full-frame body it vignettes or triggers crop mode.

What is the Zeiss Touit 32mm f/1.8 equivalent to on APS-C?

Its focal length is already the real value for APS-C: 32 mm frames like 49 mm on full frame.

What is the Zeiss Touit 32mm f/1.8 good for?

As a standard prime it suits street, documentary, everyday and low-light shooting.
