The 24.6-megapixel camera is equipped with a full-size 35mm Bayer sensor and weighs only 370 g (less than a pound), with no battery or memory card. It is lighter than large format cameras such as the Panasonic S1 (1,021 grams with battery and card), Sony A7 (650 grams) and Canon EOS RP (485 grams). Sigma calls the fp a camera "full of pocket", and at 112.6 x 69.9 x 45.3 mm (or 4.4 x 2.75 x 1.8 inches) it will probably fit in the palm of your hand.
Sigma has not announced when the Sigma fp will be released nor how much it will cost, but the company's other mirrorless cameras range from $ 800 to $ 1,200. It is too early to predict the success of the camera. If nothing else, it is certainly ambitious.
