Sigma has announced the release date and price tag for its Sigma sd Quattro H 51-megapixel digital camera.

The Sigma sd Quattro H price tag will be £1,499.99 with a release date set for January 2017, Sigma says.

Announced in June 2016, the Sigma sd Quattro H features the company’s newly developed APS-H-format Foveon X3 Quattro image sensor, which offers 51 megapixels (equivalent) resolution.

By ‘equivalent’, Sigma means that other cameras typically use a single-layer photo sensor covered by a Bayer filter mosaic, which comprises 50% green, 25% blue, and 25% red squares.

However, the Foveon X3 Quattro direct image sensor uses no low-pass filter and is able to capture 100% of the data for blue, green, and red in each of its three layers, Sigma says.

Due to this structure, Sigma says the Foveon X3 Quattro direct image sensor can generate up to twice the resolution data of sensors using a Bayer filter.

The SIGMA sd Quattro H features a newly developed APS-H size sensor (which measures 26.7 x 17.9mm) with 25.5 megapixels in its top layer for an equivalent total of approximately 51 megapixels.

The Sigma sd Quattro H also features the Sigma SA mount and is compatible with all of the company’s Contemporary, Art and Sports lenses.
