The new compact interchangeable lens camera Panasonic Lumix GX7 is a team of the most professional market given its size. Recognized by the performance of its sensor, as well as the quality of its electronic viewfinder and screen both Swing, the new GX7 is presented as the improved version of the previous model GX1 from Panasonic. Like its predecessor is a Micro Four Thirds camera with ergonomics and retro design that does not leave anyone indifferent. We will then review the main features of this new model Lumix of interchangeable lenses of the firm Panasonic.
The sensor of the GX7 is the new Live MOS that despite being small gets a good picture quality allowing resolution of 16 megapixels. Its main feature enabling aspect ratio of 4:3 is why the new GX7 camera is a Micro Four Thirds. The improvements in the sensor are remarkable in two respects: first in the performance of the ISO value (value that measures the sensor’s sensitivity to light) and, on the other hand, the image quality and a capture rate of the chamber.
So with these sensor characteristics, we can raise the ISO to 1600 to take pictures at night without worrying about the noise that takes the form of grain when we see the pictures on a larger screen, such as the computer. This value ISO is quite high, so allow us to take pictures at any time and with very little light. If we do not mind the noise, we can always increase the ISO value to 6400 in that while we have a little grain, the color reproduction will remain quite faithful to reality.
Anyway, the new GX7 supports a maximum ISO of up to 25600, which is very high so we will reserve for cases of extreme necessity, sacrificing the quality of the final result. What is obvious is that it is an important characteristic because you have to keep in mind that this camera sensor is smaller than that of professional cameras, so it shows that the new sensor Live MOS of the GX7 has a great performance despite its size.
Another fact worth mentioning is that, thanks to the characteristics of this sensor, the dynamic range of the photo is much higher. This means that, when taking pictures that have different illuminations (in part sun shade and one with) the general light photography is balanced between its darkest and lightest point.
We mentioned before that the size of the images in the GX7 is 16 megapixels. It is the largest on the market, however it is a size completely adapted to both the camera sensor as the means in which we are going to play our photos: Unless you want to make copies of large size, 16 megapixels is more that enough to view pictures on a computer monitor or even a television in the room.
Finally, note that, thanks to the sensor Live MOS, the new GX7 can make a flurry of shots at a speed of 5 frames per second with the electronic shutter and up to 40 frames per second in RAW format. The electronic shutter is the system by which the new GX7 can shoot silently, however we sacrifice shutter speed, ie the mechanical shutter can shoot at a speed of 1/8000 seconds, however, the system of sealing e have to reduce it to 1/2000 second, a speed that enough for normal light conditions. In addition, thanks to the stabilization IBIS the GX7 incorporating in its body, shoot at lower speeds won’t be a problem for the approach to photography.
The new GX7 not only lets you take pictures with a good image quality, but also records good video to HD resolution of 1920 x 1080 pixels at 50p. As for the quality of the sound recording, if we do not want you to give a professional, be good enough, considering that has a filter that significantly reduces the noise that the wind could cause the audio input of the camera.
Moreover, the great advantage of the GX7 is its fast autofocus system 23 zones. The new GX7 has three modes of auto focus: the simple, the flexibility and continuous. Most interesting to record video is its flexible autofocus mode as pressing the shutter button halfway, the camera can tell the subject that we want to come out focused and if it moves, the focus automatically moves with it. Powered by contrast, but the autofocus performs very well even in low light conditions thanks to its mode Low Light AF.
Anyway, there are other possibilities to focus while recording video are we Peninsulas also be very useful, one is the manual focus through the ring of the lens. The other is that, thanks to its touch screen, we can focus directly supporting finger on what we want to come out sharp and while this move, the autofocus makes tracking in the same way that if you activate with the trigger and avoid over Pulse problems.
