      Photography Features

      Pentax K20D can take pictures up to 4672 x 3104 resolution. It can also take pictures with lower resolution like 3872 x 2592, 3008 x 2000, 1824 x 1216 with 3:2 aspect ratios. Pentax K100D Super can take pictures up to 3008 x 2008 resolution. It can also take pictures with lower resolution like 2400 x 1600, 1536 x 1024 with 3:2 aspect ratios.


      Lens Mount

      Cameras have Pentax KAF2 lens mount. Due to their APS-C sensor their crop factor (also called lens multiplier) is equal to 1.5x. This means that a 35mm equivalent focal length of the mounted lens will be equal to its actual focal length times 1.5.


      In-Body Image Stabilization

      The cameras have a built-in Sensor Shift in-body image stabilization (IBIS). This means that you are still getting vibration reduction when cameras are paired with non-image stabilizied lenses. It also works with lenses with optical image stabilization and in combination can achieve even better compensation.

      Connectivity, Battery and Storage

      USB Inputs

      Both models have USB 2.0 (480 Mbit/sec) inputs for data transfer.


      Battery
