The Sony A7R (α7R) is a compact system camera with a 35mm full-frame sensor offering 36.4 effective megapixels and no optical low-pass filter. The sensor emplys a new ‘gapless’ on-chip microlens design which eliminates gaps between adjacent pixels. These advances increase light collection efficiency, achieving outstanding resolution, sensitivity and low noise while circumventing the challenge of decreased pixel size due to the extremely high pixel count. Other highlights include a Sony E bayonet mount (designed to be used primarily with the company's new full-frame E-mount lenses), a dust/moisture-resistant magnesium alloy body, newly-developed fast intelligent auto focus, an improved XGA OLED electronic viewfinder, NFC and Wi-Fi capabilities, Full HD movie recording and 4K photo output for viewing on Ultra HD displays and TVs. Priced at £1600 / $2299 and available for pre-order, the Sony α7R will go on general sale in UK from mid-late November.
