Dear Everybody , Well, I've finally done it and have ordered an RX1R - My bank account is somewhat depleted And now I need to purchase UV and Polariser filters. Are the following okay for the RX1 ? B+W 49mm XS-Pro Clear UV Haze with Multi-Resistant Nano Coating (010M) B+W 49mm Kasemann Circular Polarising MRC Filter Does anybody use these on their RX1 ? I ask as I understand that some B+W filters are too slim which means that the sony lens cap cannot grip on properly ! Secondly , is a circular polariser okay with the sony focusing system ! Thank you much. Adam.
