To start the camera is tropicalized. Honestly, I have never paid too much attention to my Q during the rain, but being able to shoot in any weather condition without worry is a big deal.
Then we have the new sensor with 47 million pixels. A lot of pixels means not only very detailed images but also have a creative tool at our disposal that can allow us to take photographs far more distant from the subjects, knowing that then it will be possible to make even greater crops.
Another exciting feature is that with that kind of resolution the 35mm and 50mm modes now have much more available resolutions. We are talking about 30 Megapixels at 35mm, 15 Megapixels at 50mm and 6.57 Megapixels at 75mm.
The integrated optic is still the incredible Summilux 28 mm f / 1.7 ASPH. with eleven elements (including three aspherical) divided into nine groups.
If you are into 28mm lenses, this is the best you can get. Period.
