First, by the integration of a sensor 4/3 (17.3 x 13 mm) and a 24-75 mm zoom f / 1.7-2.8. This couple, supported by the processing engine Venus Engine data to allow the camera to deliver beautiful images to ISO 1600 and climb without much difficulty until 3200 ISO. The optical power zoom is also of good quality, with good sharpness throughout the zoom range and the center, which is usual, edges a little "soft" wide open.
In terms of ergonomics, we appreciate the direct access to the aperture (optical) and exposure time (wheel) - Settings old probably inspired by Leica, a partner at the design of the optics. The LX100 has 3 buttons and a customizable rear thumbwheel to quickly change options shooting.
The development is a treat in automatic mode. The AF system is probably the best performing market in contrast detection. It gives excellent results both photo and video recording. Focus is fast and tracking AF is fast and accurate enough to keep pace with 11 fps. In video, the LX100 also provide satisfaction in terms of image quality including excellent 4K TV mode.
However engineers have failed micro and headphone jacks. In addition, however, we regret the absence of a swivel LCD and touch screen. These features are now commonplace, and they have found their perfect places on advanced cameras.
Despite some flaws, the Panasonic LX100 is the expert compact of the moment and receives our high recommendation.
