The Leica Q2 is an advanced compact camera characterized by its updated sensor design and intuitive operation. Revolving around a revised full-frame 47.3MP CMOS sensor and Maestro II image processor, high-resolution stills shooting is possible as well as both DCI and UHD 4K video recording. The image processor also contributes to a broad ISO 50-50000 sensitivity range plus quick 10-fps full-resolution continuous shooting.

A high-resolution 3.68MP OLED electronic viewfinder is featured for fluid and clear eye-level monitoring and a rear 3.0" 1.04m-dot touchscreen LCD also affords straightforward playback and settings control. Built-in Bluetooth LE and Wi-Fi permit wireless sharing and remote camera control from a linked mobile device via the Leica FOTOS app. Stills can be recorded as 14-bit DNG files and JPEGs. The added resolution also enables unique digital zoom capabilities to simulate working with different focal length lenses: 30MP images can be created using a 35mm field of view, 15MP images with a 50mm field of view, and 7MP with a 75mm field of view.

Extending its versatility, a dedicated macro-focusing position can also be used for working with subjects as close as 6.7" away. Additionally, optical image stabilization helps to compensate for the effects of camera shake for sharper handheld shooting. The rear 3.0" 1.04m-dot LCD features a touchscreen design for intuitive navigation and playback, as well as the ability to touch to focus. Adoption of the BP-SCL4 battery, as used with the SL (Typ 601) mirrorless camera, affords an improved 370 shots per charge and the battery's physical design incorporates a rubber gasket to further reinforce the overall weather sealing.
