Panasonic's LX series of compact cameras, such as the Panasonic LX7 have found favour in the past because of their high quality build, extensive array of controls (for a compact camera) and impressive image quality. However, the arrival of cameras like the Fuji X100S and Sony RX100 III raised questions about the small size of the sensor inside the Panasonic camera. Panasonic's answer is the LX100, which features a Four Thirds-type sensor instead of the 1/1.7-inch device in the LX7. That's going to give it an edge over the Fuji X30 announced recently.Further good news is that the sensor is the same 16-million pixel device as is used in the Panasonic GX7. However, as the LX100 uses Panasonic's Multi Aspect Ratio technology, images only ever use 12.8 million pixels.
