Lens Mount

Canon EOS Rebel SL1 has Canon EF/EF-S lens mount and Pentax K10D has Pentax K_AF2 lens mount. They both have APS-C sensor but because of a small size difference their crop factors (also called lens multiplier) differ from each other. Canon EOS Rebel SL1 has the crop factor of 1.6x which means that a 35mm equivalent focal length of the mounted lens will be equal to its actual focal length times 1.6. Pentax K10D has the crop factor of 1.5x which 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 on Pentax K10D

Pentax K10D 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.
