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 100 mm	At 173 mm	At 300 mm	Equiv. aperture (DoF)
Micro Four Thirds	200 mm · 12°	346 mm · 7°	600 mm · 4°	f/8.0

Depth of field & background blur#

Computed on its native Four Thirds format (CoC 15 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: 105 mm f/4 on four thirds.
