During the last Photokina fairs, we could see the prototypes of full-frame Panasonic S1 and S1R for the first time, but their official premieres took place only a few days ago. The cameras are very similar to each other when it comes to the construction, but they have different sensors and offer different film-making functions.
Panasonic Lumix S1R
SR1 is a more advanced construction of the two. The camera has been equipped with the 47.3MP CMOS sensor with the nominal ISO range of ISO 100 - 25600. The Venus Engine image processor and a new system of micro-lenses are responsible for high detailedness, wide dynamics, perfect color mapping and a low level of noise while taking photographs at high sensitivities. The users will be able to create profiles of JPEG files on their own, use the automatic white balance mode with white priority as well as save RAW photographs in the HGL mode.
The camera’s high resolution mode will make it possible to take photographs with the resolution of up to 187MP. It will take place through combining 8 frames taken with proper shifting. This function is based on the sensor stabilization system. The photographs taken in the high resolution mode can be saved in the RAW format.
Panasonic S1R has been equipped with the stabilization with the effectiveness of 5.5EV and the AF supported with artificial intelligence. The stabilization’s effectiveness can be increased to 6EV if we use the O.I.S lens, Dual I.S system. During film-making, we will be able to use the stabilization at the level of 6EV if we apply 24-105mm f/4 or 70-200mm f/4 lenses.
The DFD (Depth From Defocus) autofocus system is based on phase detection – it is Panasonic’s original solution which has proved its high efficiency many times. The system works with the speed of 480f/s and it enables focusing within 0.08s. The AF’s possibilities will be used fully when we apply the electronic shutter. The camera’s “Artificial Intelligence” recognizes objects such as people, dogs, cats or birds, tracks them and anticipates their subsequent movements. The AI’s work is supported by the face, eye and pupil detection systems.
Although it is the second from the cameras described today which has been designed having in mind photographing more dynamic actions, S1R is not far behind. With full AF support, the series of photographs can be takes with the speed of 6f/s or 9f/s (in the case of single measurement). With the use of the 6K Photo and 4K Photo modes, we will take 18MP or 8MP photographs with the speed of, respectively, 30f/s and 60f/s.
Since the first contact with S1R last year, we knew that Panasonic will put a lot of effort in order to satisfy the film-making lovers. The camera records in 4K with the speed of 60f/s, or in Full HD with the speed of 180f/s – the material is saved directly on SD or XQD cards. The camera is equipped with the headphone and microphone connectors. Still, the film-making lovers should pay more attention to the extended possibilities of the S1 model in this regard.
Panasonic Lumix S1
S1 is equipped with the 24MP sensor with the ISO range of 100 – 51200. The photographs taken in the high resolution mode can have even 96MP. When it comes to photography, these are the only differences in comparison to the S1R model, which has just been described. The cameras have the same body so they do not differ in terms of ergonomics. They are also equipped with the same AF, stabilization and continuous shooting modes. A big advantage of S1 is a much more extended film-making system and a much lower price.
Panasonic S1 records films in 4K with the speed of 60f/s and saves them directly on SD or XQD cards. The camera offers 8-bit save with 4:2:0 sampling. In the case of using an external recorder, films can be saved with 4:2:2 sampling. For 2019, the producer has announced sharing the key to the software thanks to which we will unlock the 10-bit 4:2:2 save in 30f/s, in the case of saving on cards, or 60f/s, in the case of a recorder. The update will enable the use of a flat V-Log image profile.
In Full HD, we will save material with the speed of 180f/s, whereas the Hybrid Log Gamma (HGL) profile will enable easy creation of the materials with extended dynamics. We will also have a possibility of controlling the gamma curve and the selection of standards, such as Like709 or Cinelike D/V. With the use of S1 we will also be able to record videos in the HEVC (H.265) standard. The camera is also equipped with the headphone and microphone connectors.
The bodies of the two cameras are identical – they are made of magnesium, fully sealed and resistant to splashes and dust. They can work in low temperatures, up to -10°C. The arrangement of buttons and knobs of both cameras is very functional. They both have the AF joystick. The body is crowned with the OLED electronic viewfinder of record-high detailedness, whose resolution amounts to 5.76MP, contrast – 10 000:1 and the refresh rate – 120f/s. The viewfinder has zoom regulated within the range of 0.7-0.78×.
The touch screens of the cameras can be rotated in both ways and they have the diagonal of 3.2’’. Their resolution is 2.1MP and they are equipped with the night mode and the Live View Boost function, which should facilitate night work with the cameras. The backlit buttons and a very big auxiliary screen placed on the upper panel are also of certain importance. Two slots for the SD and XQD cards should make it possible to work with the CFexpress cards soon.
The camera’s shutter lifetime is estimated for 400 thousand cycles. S1 and S1R offer the shortest flash synchronization time in their class – it amounts to 1/320s. The cameras have been equipped with Wi-Fi and Bluetooth, thanks to which we will get a possibility of controlling cameras and we will have continuous connectivity with the devices such as smartphones. Wi-fi and Bluetooth will also enable immediate sending of files through Lumix Sync. Lumix Tether will be responsible for tethering with the use of the USB cable.
The cameras will appear on sale in April. The body of S1 will cost $2,500 and S1R – $3,700. The cameras will be also available in the sets with the 24-105mm f/4 lens, and their prices will then amount to, respectively, $3,400 and $4,600. Together with the premiere of the cameras, numerous accessories, for instance the battery grip, the flash, the eyecup and the adapter enabling powering the camera with the use of the charger, will also appear on sale.
