      Photography Features

      Canon EOS 30D can take pictures up to 3504 x 2336 resolution. It can also take pictures with lower resolution like 2544 x 1696, 1728 x 1152 with 3:2 aspect ratios. Canon EOS 20Da can take pictures up to 3504 x 2336 resolution. It can also take pictures with lower resolution like 2544 x 1696, 1728 x 1152 with 3:2 aspect ratios.


      Lens Mount

      Cameras have Canon EF/EF-S lens mount. Due to their APS-C sensor their crop factor (also called lens multiplier) is equal to 1.6x. This means that a 35mm equivalent focal length of the mounted lens will be equal to its actual focal length times 1.6.


      No Image Stabilization

      The cameras do not have image stabilization. On Canon EOS 30D it means that you need lenses with optical image stabilization for vibration reduction. As for Canon EOS 20Da nothing can be done.
