A: The crop factor of a Pentax with APS-C sensor is 1.5. The image of a 300mm lens on this sensor is equivalent to a 450mm lens image on a full-frame sensor. Please note that this Pentax 300mm DA lens is designed for APS-C sensor. If used on a full-frame sensor Pentax camera, the periphery of the image (i.e. outside of the cropped area) may be degraded and not as sharp.
