[1] The DSC-RX1R, released in 2013, is a variant of the Sony DSC-RX1 without anti-aliasing filter in front of the image sensor.

The camera is equipped with a 24.3-megapixel full-frame CMOS sensor, and it includes a new Multi Interface Shoe[3] that is physically compatible with the ISO 518 standard hot shoe, with electrical contacts for newer Sony shoe-mounted accessories as well as compatibility with the proprietary iISO flash shoe via the ADP-MAA adapter.

This can slightly increase the effective resolution at the expense of possibly more moiré in areas with fine repeating textures.

[7][8][9] It is the first camera in mass production featuring a continuously variable optical low pass filter.

In contrast with conceptually related technology debuted in the Pentax K-3 and subsequently carried by other Pentax models, Sony's technology works at any shutter speed.
