The camera has an optical variable low pass filter, allowing photographers to manually adjust the balance of image resolution and presence of moiré or colour artifacts.
Sony has announced a new camera from its Cyber-shot RX brand, which is known for its small full-frame cameras. The Sony RX1R II palm-sized camera has a 42.4-megapixel full-frame Exmor R CMOS sensor paired with a large aperture ZEISS Sonnar T 35mm F2 lens, capable of capturing sharp images as close as 14cm, thanks to a Macro shift ring.
However, the feature that separates the RX1R II from all cameras is its optical variable low-pass filter—a first of its kind—allowing photographers to “manually adjust the balance of image resolution and presence of moiré or colour artifacts to match the subject.” In layman’s terms, the feature gives you the freedom to control the low pass filter. You can turn it off to prioritize high resolution, and turn it on to prioritize color or moire reduction.
The low-pass filter has three settings: off, standard, and high. “Off” provides comparable effects to having no low-pass filter and is suitable when prioritising resolution, “standard” balances resolution and the removal of moire and colour artifacts, and “high” puts more emphasis on reducing moire and artifacting, Sony said.
The older RX1 and RX1R cameras scrapped the anti-aliasing feature in favour of sharpness, resulting to many moire patterns, which appear when an object has repeating details, such as lines or dots. Other cameras in the market either have or don’t have a low pass filter, but Sony, as a pioneer in cameras, found a way to squeeze both features in the RX1R II.
Another new feature of the camera is its built-in retractable 2.4-million-dot XGA OLED electric viewfinder (EVF) that pops up in a single push. In addition, there is a 3-inch LCD screen, too, that can tilt upwards to 109 degrees and downwards to 41 degrees, NFC compatibility, and support for full HD 1920x1080 video recording (sorry, no 4K). This camera commands a premium price of $3,300 when it arrives in November.
