Camera can take pictures up to 4000 x 3000 resolution. It can also take pictures with lower resolutions like 4000 x 2664, 4000 x 2248, 3456 x 2595, 3456 x 2304, 3456 x 1944, 2992 x 2992, 2688 x 2016, 2688 x 1792, 2688 x 1512, 2016 x 2016, 1920 x 1440, 1920 x 1280, 1440 x 1440 with 1:1, 4:3, 3:2, 16:9 aspect ratios.
Lens Mount
Pentax Q10 has Pentax Q lens mount. Due to 1/2.3-inch sensor its crop factor (also called lens multiplier) is 5.6x. This means that a 35mm equivalent focal length of the mounted lens will be equal to its actual focal length times 5.6.
In-Body Image Stabilization
The camera has a built-in Sensor Shift in-body image stabilization (IBIS). This means that you are still getting vibration reduction when camera is paired with non-image stabilizied lenses. It also works with lenses with optical image stabilization and in combination can achieve even better compensation.
