Right on the heels of the initial batch Leica S3 cameras being shipped out of Wetzlar, Leica has already issued a firmware update, version 1.1. Mainly, the new firmware improves image quality output, especially at higher ISO settings, as well as fixing a few small bugs. Obviously, this firmware is strictly for the newly-introduced Leica S3, not any previous model Leica S camera.
