  • More prone to moire, aliasing and false color than the RX1; Only subtle improvement in sharpness in RAW files; Fixed-length lens limits shooting flexibility; Viewfinders (optical or electronic) only available as optional accessories; Extremely expensive for a compact camera.

  • Great image quality; Good high ISO performance for its class; Improved JPEG processing; Fast autofocus; Fast ~9fps burst mode.

  • Smallish field-sequential EVF; Below average battery life; No mic/headphone jacks; Noticeable crop on 4K video.
