The new mirrorless Panasonic Lumix S5 offers compact dimensions and at the same time a large full format sensor with 24 megapixels. As with the S1 and in contrast to the S1H, no low-pass filter was installed. The camera is significantly more compact than all S1 sisters and even smaller than the GH5. With the dimensions 13.3 x 9.7 x 8.2 cm and the weight of 712 g it is in the same order of magnitude as the Sony Alpha 7 series.
Many features were taken over from the larger S1(H), for example the S5 also has Dual-Native-ISO technology (at VLog Panasonic specifies 640 and 4.000 as BASE ISO) and a internal 5-axis image stabilization. The operating layout is identical and you can even find some professional assist functions like time code, frame marker, upright video, wave form monitor, zebra pattern, luminance spot meter, knee control/Like709 or even a tally function.
The DFD high-speed autofocus is to be improved and use real-time deep learning technology to optimally recognize the eyes, head and body of humans and animals and thus focus more precisely. The dynamic range is to be 14+ f-stops as with the full-format sister models.
Lumix S5 with Atomos Ninja V
The camera films internally in 4K resolutions only up to 30p with full sensor readout with maximum 4:2:2 (10 bit). In a S35 crop it can achieve up to 4K/UHD 60p 4:2:0 (10-bit), externally via HDMI output these can also be output as 4K 60p 4:2:2 (10-bit). A firmware update in 2020 will enable a external RAW output for Atomos Ninja V Recorder in 5.9K 29.97p/25p or 4K (4128 x 2176) 59.94p/50p and also support anamorphic recording in 3.5K (3536 x 2656) up to 50p.
For the 4K / 10 bit recording modes as well as for 4K 50p in 8 bit, Panasonic specifies a recording limit of 30 minutes, but the camera should be able to continue filming without a cooling phase afterwards. In 4K with 8 bit up to 30p as well as in FullHD there are no time limits, also an anamorphic mode, which is read out in the APS-C Crop, is unlimited in 8Bit also with 50p.
Slow & Quick modes are included and range from 4K to 60fps and in FullHD to 180fps (for 30 minutes). HDR is also on board as Like2100 / HLG, as well as V-Log and Cinelike Gamma. The S5 does not offer an All-I compression.
Both the OLED viewfinder with 2.36 million pixels and the foldable and tiltable 3-inch touch display with 1.84 million pixels have a lower resolution than the larger S1(H). The magnesium housing is protected against dust and splash water and offers two SDXC memory card slots, one of which is compatible with the UHS-II (V90) transmission standard, the other only with UHS-I. Interfaces include USB-C, a Micro-HDMI TypeD connector, a microphone input (3.5mm, XLR optional via adapter) and a headphone output. Lenses are connected via L-Mount.
For the Lumix S5, Panasonic uses a new rechargeable battery (DMW-BLK22) with a higher capacity compared to the battery of the GH5 (2,200mAh instead of 1,860mAh); it is also backwards compatible with the GH5. The battery can be charged via the USB-C port in the camera or with an external charging adapter. The USB-C port can also be used directly for power supply.
The Lumix S5 will be available in stores at the end of September 2020 as a housing for 1,948.61 Euro and in a kit with the 20-60mm S-lens for 2,241.04 Euro. As special promotion, customers who purchase the camera from participating retailers by September 30, 2020 will receive a free Sigma 45mm/ F2.8 DG DN / Contemporary lens worth 569€ RRP (as of August 2020).
S Series Lenses
The range of L-Mount lenses is also being expanded, as announced by Panasonic in the form of a roadmap. There will be a new S Series, which will initially include the four fast fixed focal lengths 24mm F1.8, 35mm F1.8, 50mm F1.8 and 85mm F1.8 as well as the zoom lens 70-300mm F4.5-5.6. The 85mm will be released in November, the other lenses will follow in the "near future".
