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 10 mm	At 13 mm	At 18 mm	Equiv. aperture (DoF)
APS-C	15 mm · 109°	20 mm · 95°	27 mm · 76°	f/4.2
APS-C (Canon)	16 mm · 107°	21 mm · 92°	29 mm · 73°	f/4.5
Micro Four Thirds	20 mm · 95°	26 mm · 80°	36 mm · 62°	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: 14 mm f/2.8 on aps-c.

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).
