New Nikon Patent Shows On/Off Switch for Anti-Aliasing Filter

When Nikon released its D800E and D7100, people were surprised to learn that these models did without the Optical Low Pass Filter (aka. the Anti-Aliasing Filter). The resulting images from these cameras were sharper, but more easily fell pray to moire patterns in certain situations -- in other words, it was a tradeoff.

But Nikon would like you to have your cake and eat it too, at least according to a recent patent the company filed with the Japanese Patent Office.

Sony RX1R Bests the RX1 in Sharpness by Ditching the Anti-Aliasing Filter

Sony now has two full frame compact cameras in its lineup---kinda. The company today announced the RX1R, a souped up (or perhaps stripped down?) version of the RX1 that shoots sharper photographs by ditching the anti-aliasing filter in front of the sensor. Aside from the lack of an AA filter, the RX1R and its sibling are virtually identical cameras.
