As I understand it, there is no photographic difference between a linear and a circular polariser. A LP stops most autofocus systems from working as they rely on detecting the light's phase shift between two different points of the lens which is effectively cancelled out by the LP. A CP adds a quarter-wave plate behind the polarising element which rotates the light in a spiral pattern. To the autofocus system, it now looks just like the light entering an unfiltered lens where the light is vibrating in all different planes.
You can still use a LP but you'll have to focus old skool.
