DJI has introduced the Osmo Action 6, an action camera built around a new square Type 1/1.1 CMOS sensor and notable for being the first device of its type to use a variable aperture. The lens indeed shifts between f/2.0 and f/4.0, a range that departs from the fixed-aperture designs typical in the category, and is intended to provide more control over depth of field and exposure. In Auto mode, the camera regulates the aperture between its minimum and maximum values, while additional preset modes apply fixed settings, including a starburst effect at f/4.0. The minimum focus distance can also be shortened from 35 to 11 centimeters, with a Macro Lens sold separately.

The Osmo Action 6 camera’s square sensor layout, which covers 98 mm² and uses 2.4 μm pixels, allows recording in 4:3, 16:9, and a 4K Custom format that captures the full sensor for later reframing. DJI states that the sensor offers up to 13.5 stops of dynamic range. The camera records up to 4K/120 in 4:3, supports 10-bit D-Log M, and features a SuperNight mode for low-light recording, though capped at 4K/60. Frame interpolation is used to create 32× slow-motion footage, producing the equivalent of 960 fps output from native 1080p240 capture. The camera records in HEVC at bitrates up to 120 Mbps and captures still photos at 38 megapixels.

Electronic stabilization is carried over from earlier models, including RockSteady and horizon-leveling modes. HorizonSteady now operates in 4K, and HorizonBalancing supports correction within ±45 degrees. The camera also includes subject detection, tracking, and automated centering, using the processor to adjust framing and composition. Additional modes cover portrait-oriented capture, various built-in tone profiles, and a new system for maintaining skin-tone consistency.
