Leica Q (Typ 116)

Advantages: Superb picture quality!
Ergonomics and menu convenience.
Full frame with a great lens.
The quality of materials and performance.
Very fast autofocus.
Ergonomics
Compactness and weight
Touchscreen
Price, in comparison with the M series

Disadvantages: A weak battery, but decided to buy 2-3 Panasonic Lumix batteries (the same battery under different brands and at different prices). There is a lack of more flexible configuration of the function buttons. Perhaps not enough focus area adjustment.

Comment: Great camera for street photography, travel, landscape. If desired, get very good portraits. In the hands is not bad, with an additional handle and emphasis almost perfectly. Excellent balance, weight and size. Corporate "Leykovsky" color allows you to shoot in jpeg plus amazing detail. The latest firmware has fixed problems with the display and WiFi pairing errors. In general, the best camera in its class.

Advantages: Weight, size, ergonomics, color, sharpness, drawing, ISO.Excellent everyday camera for any needs and travel.
Very quiet mechanical shutter and generally silent electronic. I tried to make a straight with my cell phone. The camera hangs on the neck, you look at the picture on the mobile phone, imperceptibly direct the camera to the plot, you shoot through the sensor of the mobile phone. Even in the library they will not suspect :)

Disadvantages: Batteries quickly die in the cold, but with a two spare from Panasonic, basking in your pocket. However, it is inconvenient to change the batteries if you use the DOF: you must first unscrew the handle, pull out the battery, insert a new one, fasten the DOF. So the pen has to be used only in the warm season.
Autofocus compared to the SLR is still not perfect, the benefit is realized by an excellent manual focus. On sports subjects, tracking in general almost fails. But in the portrait it takes a long time to get used to the use of modes. It seems to put a point on the eye, took a picture, but all the same, only the ear is sharp.

Comment: I will add other commentators with my experience.
Strangely enough, but from DNG it is not so easy to get a result from the color that the camera gives to JPG, you must be able to seriously color. In a lightroom, the color that was red in the cut may turn out to be maroon-purple. Began to shoot only in zhpege, but there is a snag: there is no option to emulate the exposure on the screen or viewfinder. At first glance, the camera darkens the image, if you direct it to the lamp, it lightens, if you translate it into shadow, but in fact you should only carefully monitor the scale of the exposure meter and it is better to use spot metering.
In difficult conditions, the autoBB may not behave very well, but threw a gray card into the bag with the camera. The ability to save two gray card profiles in the settings is just fine. Not once used this option.
Suddenly, the first purchased camera turned out to be defective: the viewfinder was too contrast, the scale on the lens was not working properly (you cannot adjust the hyperfocal). The camera was replaced (the benefit of bought the official), with no new problems.

Advantages: 1. Excellent picture quality!
2. Great lens
3. Workmanship
4. Excellent stabilizer
5. Compactness, inconspicuousness and weight
6. Availability and operation of autofocus
7. Price, in comparison with M
8. Ergonomics and menu convenience

Disadvantages: 1. There are errors when pairing via Wi-Fi
2. The price tag in Russia is significantly higher than in Europe, and even more so, the United States.
3. One more custom button is missing for quick access to parameters.

Comment: Awesome image quality. Color and detail at the height. Compared with its Canon 5D MkIII + 35 1.4L. Canon then sold out quickly.

The camera delivers a previously unknown pleasure, both from the process of shooting and from the result.

Not replaceable lens consider a plus. Although it would have been more familiar to get 35 mm in its quality.

If Leica had released the same camera with another 50 mm lens, it would have sold its Nikon D810.
