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 90 mm	Equiv. aperture (DoF)
APS-C	135 mm · 18°	f/3.0
APS-C (Canon)	144 mm · 17°	f/3.2
Micro Four Thirds	180 mm · 14°	f/4.0

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: 85 mm f/2 on aps-c.

Focal	Aperture	at 1 m	at 2 m	at 5 m	at 10 m	Hyperfocal	Blur @2 m
90 mm	f/2	0.9 cm	3.7 cm	23.7 cm	95.9 cm	207 m	9.0%
90 mm	f/4	1.8 cm	7.4 cm	47.5 cm	1.93 m	104 m	4.5%
90 mm	f/8	3.5 cm	14.8 cm	95.7 cm	3.97 m	51.9 m	2.3%

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 90 mm	NPF at 90 mm, f/2
APS-C	1/125 s	4 s	2 s
APS-C (Canon)	1/160 s	3 s	2 s
Micro Four Thirds	1/200 s	3 s	2 s
