In the intricate camera industry, various manufacturers have changed their cameras from bayonet to bayonet and patented the bayonet in order to make the lens self-produced and sold. New manufacturers involved in the camera industry often need to develop new bayonet systems themselves, which are costly and face many patent barriers. In this case, more and more emerging manufacturers such as small ants, large Xinjiang, Mito and others have focused their attention on the M43 system. The M43 is an open source system. Just like Android in mobile phones, any manufacturer can use it, which greatly reduces the manufacturer's threshold.
But this article is not to tell the story of a small manufacturer. The protagonist of this article is Panasonic, one of the two giants of M43.
Panasonic and Jianghu are known as “Panasonic†and joke is a joke. Panasonic and Sony have always been confrontational opponents in the video field. In recent years, Sony and Panasonic have even competed for the lack of anti-camera development. Expanding into the camera field, in the face of the powerful offensive of the Sony A7SII, Panasonic finally released its flagship M43 non-reverse camera, the GH5, this year.
About GH5When it comes to the Panasonic GH5, people must think of its powerful video capabilities. Indeed, as stated in the publicity, the biggest selling point of the GH5 is also its video shooting capabilities. However, both from the appearance and from the website of the official website, point to a fact: This is a camera rather than a camera.
Panasonic Panasonic DC-GH5LGK (Fuel + Leica Lens) Mini Single Electric Cover (6K Photo, 4:2:2 10bit Video Recording, 20.3 Megapixels) 17,998 yuan Jingdong to buy The biggest difference of GH5 in GH4 is that it adopts a whole new generation of LiveMOS. This LiveMOS has 20 million pixels, which is the highest pixel in the M43 system. And thanks to this LiveMOS, the GH5's focusing ability is from the previous generation. The 49 points were upgraded to the current 225 points, truly achieving a quantum leap in focus. As the most important video function, although the previous generation GH4 can shoot 4k video, but only 4:2:0 8bit, upgrade shooting is only 96p, and GH5 is upgraded to 4:2:2 10bit up to 150Mbps stream, The upgrade shot has reached 180p, and at the same time it can support the V-Log function. The space in the later period is greatly enhanced, which is very convenient for video shooters.
The GH5 also conforms to the trend of the times and added a five-axis image stabilization function. In the previous generation of machines, there was no image stabilization. When shooting video, the stabilizer was used in large cases. With the addition of five-axis image stabilization, Panasonic was added. The huge anti-shake lens group can be hand-held at many times, making it easier for video shooters to shoot.
From a volume point of view, the GH5 is a bit too large in the M43 family, but only in this way can it reflect its professionalism. After all, the large body can accommodate more buttons and dials, and the large body also brings For a better grip experience, the large-area skin has a nice non-slip effect and feels more comfortable to prevent the camera from falling off.
The arrangement of the top of the aircraft is basically the same as that of the previous generation. One mode dial, one shooting wheel, four small buttons, and the huge video button moved from the back to the top, indicating the identity of its video machine. The warships are a lot shorter than the GH4, and the infighting is also canceled (what is the internal flash of the video machine)?
From the behind, the key layout of the GH5 is basically the same as that of the GH4. It is still a continuation of the previous generation of double-dial designs. This looks like some older cameras like the film era. Similarly, the flip screen has not been cancelled. The flip screen is more flexible. This design is similar to the Canon SLR. The continuation of the previous generation's design can not only save costs, but also allow the old users who use the GH4 to get started quickly.
The GH5 has 3 dials: the front and rear dials and the back dial. In fact, this back wheel is not as comfortable as the back wheel of Canon Sony. It is easy to rub against the skin behind it during the thumb rotation process. The addition of the shifter makes the selection of the focus point more convenient, but most of the time when I actually use it is to select the focus point with the touch screen, and the feel of this lever is...
Just said GH5 big because it is compared with the M43, and in fact the GH5 is still very small compared to the current mainstream camera, with Matsushita 12-60 F2.8-4 lens can maintain a petite figure, in my When shooting outside, a GH5+12-60 F2.8-4 plus a Ricoh GR can easily be put into my Buckingham camera bag. This is almost unthinkable in previous SLR cameras.
Billingham Hadley Pro Classic Shoulder Bag One Camera Two Mirrors Flash (Black/Brown Leather Canvas) 1860 yuan Buckingham hadley pro Jingdong to buy Wikipedia 
Ricoh GR II WIFINFC phone controls superb quality, faithfully reproduces the best of one-handed control, black and white effect coquettish value 103 Comments 2 Original 6 Good price 18 To buy View details Practical test Having said so many appearances, you should look at the actual effect of this GH5. After all, it is a camera instead of a camera. Photographing ability is the key. The GH5 has replaced LiveMOS. This brings about a qualitative leap in quality. After this LiveMOS has been tuned, the picture has excellent performance. , to some extent, APS-C camera.
From the point of view of the shooting effect, this LiveMOS once appeared on the GX8 is very tolerant, at least in the M43 belongs to the top level, after the highlights of the brightening noise is not very obvious, and noise control from ISO200-3200 is not bad .
The important point of this product upgrade is the great leap forward in the ability to focus, rising from 49 to 225. Together with Panasonic's unique DFD technology, the focusing experience can be said to be a new level. I usually shoot some rock shows. The first time I tried to shoot with the M43 camera, the GH5 gave me a different feeling.
Shooting performances requires a quick and flexible response. The GH5's 225 focus points can cover almost the entire picture. Plus, the M43 itself has a very strong single-contrast focusing capability, so I won't miss a moment worth recording. The touch screen is more convenient when selecting the focus, and it can really be where to go.
Limited by the area of ​​the M43, plus the high pixels of 20.3 million, the GH5's high-performance is still worse than the full-frame camera. The lighting of the performance venue changes quickly, and the rhythm of the musician's performance is very fast. This requires that the shutter speed of not less than 1/250 sec must be maintained during shooting. Under this premise, in order to ensure the brightness of the screen can only increase the ISO, but the ISO 3200-6400, the screen noise is really a bit more, this It can be considered a serious regret.
Today 4K has become popular, as a flagship video player, 4K function is no longer its flagship, but the most basic configuration, based on this, Panasonic to the GH5 equipped with 6K photo function, 6K photo This is an evolutionary version of the 4K photo. Like the 4K photo, the principle of the 6K photo is to record a 6K resolution 30p video and then extract a frame from it to save it as a photo. 6K photo function also benefits from this new 20.3 million pixel LiveMOS, the number of pixels just to meet the 6K resolution, in fact 6K photo shooting process is not practical, because 6K photos can only be saved in a single frame, and must be in the machine Pick within.
The addition of anti-shake function has made the GH5 a great improvement both in shooting photos and shooting videos. Hand-held shooting is also possible in low-light environments. The shutter speed of this photo is only 1/20s. In five-axis image stabilization, the screen shot is still clear.
to sum upIn a short time to start a new camera, I did it on the GH5, because of the mature design allows me to seamlessly switch between the GH4 and GH5, although the camera's high sense of performance has yet to be improved, while some operating logic I'm not used to it, but new sensors, a new focusing system, 6K photos, five-axis image stabilization and other functions have changed my preconceptions about the M43, so that it can not be put down in just a few days, it's The performance makes me feel like a real M43 flagship.
If you are a video practitioner and need to shoot some high-speed pictures, then this camera is very suitable for you. If you are a new official, you want to photograph your child with the most innocent look, and you will also have some simple Video clips, then you can't miss this camera. However, if you only take pictures for a trip or just want to take pictures of family members, I am afraid that the use of such a professional camera will bring a lot of trouble. How to choose it depends on your needs.
