OM System PEN reaches UK orders at £849 for the body

By Amara Osei

OM System’s new PEN mirrorless camera now takes UK orders at £849 body-only or £949 with the M.Zuiko 14-42mm f/3.5-5.6 III lens, following its September announcement.

Wex Photo Video and Amazon UK list the camera, although some listings still await stock. The body-only model is also on sale in the US at $999.99.

“Orderable” describes the sales status, not uniform physical availability. UK buyers may still need to compare dealer inventories before committing to a project-specific purchase.

What does the PEN bring to the market?

The PEN combines a traditional rangefinder-inspired design with modern autofocus and computational photography features. OM System positions the compact body as an alternative to larger mirrorless cameras for travel, street photography and everyday assignments.

At approximately 393g, including its battery and memory card, the body retains the portability associated with the PEN range. Available in black or silver, it offers working photographers a compact option for assignments that do not require a larger mirrorless kit.

The PEN name dates to 1959, when Olympus introduced the original half-frame film camera. This fully digital interchangeable-lens model carries the series’ portability emphasis into a different format, while preserving its recognizable body design.

Which specifications matter for client work?

OM System specifies a 20.4MP Four Thirds sensor and a 121-point phase-detection autofocus system. Subject recognition is designed to track people and pets, features directly relevant to paid work involving either category.

For people or pet assignments, the stated recognition system may reduce repeated subject reacquisition during a session. That remains a manufacturer specification: no sample images, measured recognition results or comparative autofocus data accompany the announcement.

OM System claims five-axis in-body image stabilisation can compensate up to 5.5 stops. The published figure can help photographers use slower shutter speeds handheld, but it is not an independent low-light performance result.

The camera also shoots continuously at up to 30fps and provides a 2.36-million-dot electronic viewfinder for eye-level composition. OM System gives no burst-buffer capacity, sustained shooting duration or measured autofocus results, so 30fps remains a headline specification rather than a guaranteed workflow capacity.

What does the software change in the workflow?

OM System includes computational photography features familiar from its other cameras: Live ND, High Res Shot, focus stacking and multiple exposure. Dedicated colour and monochrome profiles let photographers establish image styles in-camera, reducing the need for extensive editing afterward.

Video recording reaches 4K resolution. OM System gives no frame-rate, bit-depth, codec or recording-limit details, so 4K alone does not establish suitability for a particular commercial video brief.

The body carries IPX1-rated splash resistance when paired with a suitably weather-sealed lens. Because the rating depends on the lens combination, outdoor buyers must check lens sealing rather than treating the PEN body as universally weather-protected.

Can the mount reduce equipment spending?

Unlike premium fixed-lens compact cameras, the PEN uses the Micro Four Thirds interchangeable-lens mount, the fitting that joins the camera and lens. Photographers gain access to a wide selection of lenses, including a small prime for discreet street work or telephoto and macro options.

That flexibility can serve several assignments without changing camera systems. Photographers already holding suitable lenses may direct spending toward the body rather than another lens, while new buyers can postpone a specialised lens purchase.

The £949 kit costs £100 more than the £849 body-only configuration. For photographers without suitable Micro Four Thirds lenses, the bundle supplies the M.Zuiko 14-42mm f/3.5-5.6 III lens at launch; existing owners of that lens can compare the cheaper body-only route.

With UK orders open but retailer stock uneven, the near-term business test is whether dealers replenish the body quickly. Independent shooting tests must then establish whether the stated 5.5-stop stabilisation and subject recognition perform as promised.
