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 16 mm	At 28 mm	At 50 mm	Equiv. aperture (DoF)
APS-C	24 mm · 83°	42 mm · 53°	75 mm · 32°	f/4.2
APS-C (Canon)	26 mm · 80°	45 mm · 51°	80 mm · 30°	f/4.5

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: 16 mm f/2.8 on aps-c.

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

What is the Sony DT 16-50mm f/2.8 SSM equivalent to on APS-C?

Its focal length is already the real value for APS-C: 16–50 mm frames like 25–77 mm on full frame.

What is the Sony DT 16-50mm f/2.8 SSM good for?

As a standard zoom it suits everyday shooting, travel, events and walkaround use.
