RX1

Rx1 is a model designation used in various products and contexts. The most prominent usage is Sony's RX1 series, a line of high-end compact cameras.

Sony RX1 was announced in 2012 as a premium fixed-lens camera featuring a full-frame 24.3-megapixel sensor and a fixed 35mm f/2.0 Zeiss lens. The design emphasizes image quality and portability, trading interchangeable lenses for a compact form factor. It was noted for delivering high-resolution images with strong dynamic range, though its fixed lens and premium price limited its appeal for some users.

Variants of the line include the RX1R, introduced to broaden the camera's appeal by offering an option related to the camera's optical low-pass filter, effectively allowing higher-resolution results in suitable lighting. A subsequent RX1R II model offered further improvements in resolution and processing performance while retaining the same fixed 35mm lens.

Beyond Sony, Rx1 is used as a general model designation in other electronics and software products, and the meaning can vary by manufacturer. There is no single, universally defined specification attached to the label across different contexts.

In sum, Rx1 most commonly refers to Sony's fixed-lens full-frame camera platform, with variants focusing on image sharpness and performance. Other uses are more contextual and depend on the specific product lineup.
