Panasonic LX7: Lab Test Results & Comments
The LX7 offers three focus modes: a standard AF mode; a combination of AF and Macro mode; and a Manual Focus (MF) setting. When choosing MF mode the photographer can change focus by using a small joystick near the setup dial on the back, a fast and reliable method, although of course not as comfortable as a real focus ring on the lens.
The camera offers a built-in flash system and a hot shoe on its top side for auxiliary flash units. Directly below the hot shoe and on the back an additional interface allows for an optional electronic viewfinder (DMW-LVF2) with a resolution of 1.4 million RGB dots. The LX7 has a large LCD screen on the back with a resolution of 920,000 RGB dots.
The LX7 is able to record in Raw mode and to use a studio flash system. You can open and convert the Raw image with Panasonic’s version of SilkyPix Developer Studio software. Adobe Photoshop CS6 (Camera Raw plug-in 7.2) and Adobe Lightroom 4.2 are also able to open and convert these images.
Color: Like nearly all Panasonic cameras on auto white balance, the LX7 shows a slight shift into cooler colors in darker color/gray areas and a slight yellow shift in brighter color areas. Note the bright background in the portrait shot versus the gray background in the standard test box shot. Skin tones are very good and color patterns in the test chart are reproduced with their given values. Generally there is only minor oversaturation, although red colors in the test have quite high saturation.
Sharpness: The resolution results of the LX7 are excellent. The camera showed a remarkable performance and reproduced the ISO test chart with 2731 lines of 2736 lines per picture height (sensor resolution). The large sensor and the brand-new lens system combine to do an excellent job. The sharp image reproduction is evident in the standard test box shot and the portrait shot.
Noise: The camera showed very good performance in our noise tests. Luminance noise stays under 1.0 percent up to ISO 1600. Color noise becomes noticeable in images taken with ISO 800 and higher, but is still on a very low level and even images taken with ISO 3200 are acceptable. Color noise and anti-noise filtering artifacts are clearly noticeable in images taken with ISO 6400.
The dynamic range results are on an average level: the camera gained a maximum of 9.98 f/stops at ISO 200.
