Since its release in the spring of 2019, the LUMIXS1 series of full-frame mirrorless cameras have gained excellent shooting performance, good reliability, and a wide range of L-mount lens groups. It was unanimously affirmed by many photographers. A LUMIXS1 series camera is accompanying creators all over the world, facing various shooting scenes, recording all heart-wrenching images.
Regarding the appearance lines of the LUMIXS1 series cameras, I believe everyone has no idea Strange again. But if you want to talk about its internal structure, even if you have seen the parts model on site, there are still many areas that are not clear. Today, we will follow the “Disassembly and Installation” section to dissect a LUMIXS1 camera and understand its internal world together. To watch the full video, please follow the [Songying Club] WeChat public account.
As a flagship camera, LUMIXS1 adopts an integrated magnesium alloy shell, and all seams, dials, and buttons have a dust-proof and drip-proof structure. Suitable for various harsh environments including -10℃.
To open LUMIXS1, we need to remove the EVF eyepiece cover first , Tear off part of the rubber on the fuselage. It takes some skill to open the body shell. Without understanding the fixed structure, the disassembler was driven to madness, and he chose to dismantle violently after transforming-please rest assured, Panasonic’s after-sales engineers will treat each camera more gently .
Open the body cover on the interface side, and then separate the body Top cover and back panel containing EVF. Mirrorless cameras do not have optical structures such as reflectors and pentaprisms, so the internal structure of the body is more streamlined. This is not only conducive to controlling the thickness of the fuselage and achieving a short flange distance, but also makes the placement and fixing of components more flexible-on LUMIXS1, Panasonic fixes the EVF and the back plate together.
After separating the cover, we can already see the main board of LUMIXS1 Up. The chip printed with P502X(4) in the center of the motherboard should be Panasonic’s Venus image processing engine, and the two surrounding chips are DRAM caches. The back plate of LUMIXS1 also uses a one-piece magnesium alloy, supplemented by a large number of metal protective covers. This not only provides high enough intensity, but also helps the image processor release heat.
Panasonic LUMIXS1 uses SD+XQD dual memory cards. This design not only meets the requirements of professional users for card writing speed and clearing cache time, but also provides better data reliability and transmission flexibility. But two card slots will take up a considerable amount of internal space. And XQD or CF express card will also generate a lot of heat during continuous operation, which is a test of the overall heat dissipation structure of the fuselage.
Remove the screw, separate the data cable and the connector, this time You can remove the motherboard from the camera. After removing the motherboard, we can see a whole heat shield with some thermal conductive material on it. Now, some camera manufacturers will make more hollows on the fixed plate to reduce the body weight. And Panasonic’s philosophy is obviously to give priority to ensuring strength and reliability. Throughout the dismantling process, the metal plate we saw was “one piece”.
Although the mirrorless single camera canceled the reflector and pentaprism, Most products still maintain a mechanical focal plane shutter. For high-speed photography and flash photography, the mechanical shutter is still the best choice at present, which can not only avoid image distortion, but also reduce the pressure on the processor to achieve better shooting performance. Of course, LUMIXS1 also supports a completely silent electronic shutter to meet the needs of users in different scenarios.
High-performance full-frame mechanical shutter assembly also means more parts. Through our dismantling, LUMIXS1 only has more than 35 parts in the shutter unit. They are very sophisticated and embody the beauty of a structure similar to a mechanical watch.
As the core component of the entire camera, it is true when disassembling CMOS Need some strength. In this process, the top cover of the camera can also be separated from the whole machine. Panasonic has long added touch operation functions to LUMIX cameras. But as a creative tool for professional users, LUMIXS1 still retains a large number of physical dials and buttons. These components place high demands on the design of the fuselage and the sealing structure. It is necessary to maintain reliability while not losing the touch feedback that should be provided during the control process.
LUMIXS1 provides the anti-shake function of the photosensitive element displacement. The CMOS and the anti-shake component firmware are together, and the appearance is very similar to the CMOS components of some LUMIXG series models on the M4/3 system, but in fact the size of the entire unit is much larger. On the one hand, the full-frame CMOS requires several times the driving force of the 4/3 sensor, and the larger moving range is also an important basis for achieving 6-speed anti-shake effect.
CMOS surface has IR/UV protection glass. There should be an anti-fouling coating on it, which is not easy to absorb dust. With the automatic ultrasonic dust removal function, it can ensure that no annoying stains appear in scenery and still life photography.
The entire dismantling process took us several hours, A total of about 390 parts were disassembled, including dozens of screws. All parts are securely fixed on the whole metal plate, and the control elements and the gaps in the fuselage are equipped with rubber rings and other sealing structures. The most intuitive feeling that all these bring us is precision and reliability. I believe this is the reason why the LUMIXS1 series can be recognized by a large number of creators in a short time.
良 will be equipped with a treasure knife, in order to match the powerful 4K video recording function of Panasonic S1 , Panasonic will launch the CF expressTM memory card in the near future:
is divided into two specifications of 128GB and 256GB
smoothly record high specification 4K video: read speed up to 1700MB/S, write speed Up to 1000MB/S
can work stably from 70°C to -10°C, adapting to various harsh shooting environments
