The OM System M.Zuiko Digital ED 12mm f/2.0 is an ultra-compact, all-metal prime lens offering a fast f/2 aperture and excellent sharpness. Its trade-offs include noticeable vignetting and barrel distortion at the widest aperture. Ideal for street, travel and low-light shooters who value portability.

The Sigma 16mm f/1.4 DC DN Contemporary offers a fast 16 mm focal length with excellent low-light capability and quiet stepping AF.

Professional reviewers praise the OM System 12mm f/2 for its ultra-compact build, silent MSC autofocus, and outstanding sharpness across the frame even wide open. They highlight the premium all-metal construction, precise manual-focus clutch, and excellent flare resistance from the ZERO coating. The main criticisms focus on the visible vignetting at f/2, slight barrel distortion, occasional purple fringing, and the omission of a lens hood.
Everyday users love the lens's "true magic" image quality, rapid and accurate autofocus, and the lightweight, sturdy metal body that fits comfortably in a travel kit. Common praise centers on low-light performance, portability, and the satisfying manual-focus feel. Recurring complaints involve sample-to-sample variation, noticeable vignetting and distortion at wide apertures, purple fringing in high-contrast scenes, and the lack of an included hood.

Professional reviewers commend the Sigma 16mm f/1.4 for its impressive center sharpness, bright aperture and quiet stepping AF, calling it a high-value option for Sony APS-C shooters. They note that while the lens excels in low-light and offers smooth bokeh, its corner performance at f/1.4 and occasional AF hunting in dim conditions are drawbacks, though in-camera distortion correction mitigates barrel distortion.
Everyday users generally praise the lens for its sharp images, pleasing bokeh, compact build and reliable AF in good light, appreciating the weather-sealed design for outdoor use. Recurring complaints focus on soft corners when wide open, AF inconsistency in low-light or close-up scenarios, and the lens being a bit bulkier than ultra-compact alternatives.
