OM System OM-1 Mark II Camera with 300mm f/4 PRO Lens Kit

OM System OM-1 Mark II Camera with 300mm f/4 PRO Lens Kit Summary

The OM System OM-1 Mark II with 300mm f/4 PRO Lens Kit pairs OM System’s flagship Micro Four Thirds camera body with a professional super telephoto prime lens offering a 600mm full-frame equivalent focal length. The combination targets wildlife, bird, motorsport and field sports photographers who require extended reach in a portable system that remains practical for handheld shooting.

The M.Zuiko Digital ED 300mm f/4 IS PRO includes optical stabilisation which synchronises with the camera body for enhanced handheld control at long focal lengths. Its relatively compact construction and weather sealed design make it suitable for remote outdoor use where larger super telephoto systems may become restrictive. The lens also supports close focusing at 1.4m, allowing frame-filling images of smaller subjects without changing position.

Combined with the OM-1 Mark II’s AI subject detection autofocus, blackout-free sequential shooting and advanced computational photography tools, this kit provides a lightweight alternative to larger full-frame wildlife systems while maintaining fast operational response and extensive telephoto reach.

OM System OM-1 Mark II Camera with 300mm f/4 PRO Lens Kit In More Detail

OM-System M.Zuiko Digital ED 300mm F/4 IS PRO Lens

The M.Zuiko Digital ED 300mm f/4 IS PRO provides a 600mm equivalent focal length in a comparatively lightweight Micro Four Thirds lens, making it suitable for handheld wildlife and bird photography where mobility is important. Its fixed f/4 aperture maintains consistent exposure performance while supporting subject separation and faster shutter speeds in changing outdoor light. Optical stabilisation works alongside the OM-1 Mark II body stabilisation system to reduce camera shake during long telephoto shooting.

OM System OM-1 Mark II Camera Body

Stacked Sensor

The OM-1 Mark II uses a 20.4MP stacked BSI Live MOS sensor paired with the TruePic X processor. The stacked design increases sensor readout speed, which supports reduced rolling shutter distortion, faster autofocus calculations and blackout-free sequential shooting. Continuous shooting reaches up to 50fps with continuous autofocus and auto exposure, while fixed autofocus shooting extends to 120fps.

AI Subject Detection

The autofocus system uses cross-type on-chip phase detection points across the frame and includes AI subject detection modes for birds, animals, cars, motorcycles, aircraft and trains. Tracking behaviour has been refined for more consistent subject recognition when subjects move unpredictably or pass behind foreground obstacles. Human face and eye detection remain available for portrait and event photography.

Computational Photography

Computational Photography tools are integrated directly into the shooting interface without requiring separate software or post-processing workflows. Handheld High Res Shot generates images up to 50MP, while tripod-assisted High Res Shot produces 80MP files by combining multiple exposures in-camera. Live ND supports neutral density simulation up to ND128, allowing longer shutter speeds for moving water and cloud movement in bright conditions. Focus stacking and HDR capture are also processed internally.

Image Stabilisation

The five-axis stabilisation system compensates for camera movement during handheld shooting and video recording. When paired with compatible Sync IS lenses such as the included 12-100mm f/4 IS PRO, stabilisation reaches up to 8.5 shutter speed steps in the centre of the frame. This supports handheld telephoto shooting and low-light photography without increasing ISO sensitivity unnecessarily.

Weather Sealing

The camera body uses a magnesium alloy construction with IP53-rated sealing against dust and moisture ingress. The shutter mechanism is rated for 400,000 actuations and remains operational in temperatures down to -10°C. The supplied PRO lens includes sealing throughout the lens barrel and a fluorine-coated front element which helps resist water droplets, dust and dirt during outdoor use.

Video Recording

Internal video recording supports DCI and UHD 4K recording at up to 60p, alongside Full HD high-speed recording at up to 240fps. OM-Log400 recording preserves additional tonal information for colour grading workflows, while vertical video metadata supports direct use on mobile and social media platforms. Heat management allows extended recording times without active cooling systems.

Field Handling

A redesigned rubber grip texture improves handling during prolonged outdoor use, particularly when working in wet conditions or while wearing gloves. The body includes dual UHS-II SD card slots, a dedicated CP button for Computational Photography functions and USB-C connectivity for charging, tethering and file transfer. The EVF uses a 5.76-million-dot OLED panel with up to 120fps refresh rate for smoother subject tracking during continuous shooting.

Frequently Asked Questions
