It is, but the large depth of field (because of the much smaller sensor)  
means that the AF need not be as accurate. The smaller camera also has  
much smaller pieces of glass to move when focusing.

That is not what "circular polariser" means. A CPL is basically just a  
regular linear polariser with a quarter-wave plate on the inside surface.  
The effect on the resulting image is the same.
