Reviews by professional writers and customers indicate that Leica cameras offer superb image quality when compared to other brands but come with high price tags. The Leica S and the Leica Q are two models that have received overwhelmingly positive feedback.
As of January 2016, the Leica Q is one of the few compact cameras that features a full-frame sensor, with only two other cameras by Sony offering the feature. A full-frame sensor enables the camera to take better pictures by providing noise reduction, improved dynamic range and greater control over the depth of field. Able to take pictures at resolutions up to 15.4 megapixels, the Q offers a sensitivity range of ISO 100 to 50,000, a continuous shooting mode that takes pictures at 10 frames per second, the fastest autofocus system in compact camera class as of January 2016 and a 3-inch screen to preview photographs.
Aimed at professionals, the Leica S is a more advanced model that can take pictures at resolutions up to 37.5 megapixels. Reviews praise the image quality and note that the Leica S trails the best cameras in the market very closely. The S features a CMOS image sensor manufactured by Sony, shutter speeds as fast as 1/4,000 of a second, a 2-gigabyte buffer that can handle 32-frame DNG raw buffer data and a 3-inch screen that has 640 by 480 pixels resolution.
TechRadar states that Leica uses Panasonic's factories to produce cameras. As such, Leica models usually share parts with Panasonic models.
