Two new features will be coming to the cameras, too: High Resolution Mode and High Dynamic Range (HLG Photo).
Explaining the new HLG technology, Panasonic notes: "HLG Photo allows images to be shot with a wider dynamic range. Rich, precise colour expression as close as possible to visual memory is enabled by reproducing both glaring lights and dark shadows that were likely to be overexposed or underexposed.
HLG Photos are produced as an HSP file. The user can playback these vibrant images on the latest Panasonic HLG-compliant 4KTV via HDMI cable connection or other HLG-compliant devices. It is also ideal for photo presentations by photographers."
High Resolution Mode, according to Panasonic, offers: "Stunning details with a realistic sensation. Taking advantage of the Body I.S. (Image Stabilizer) mechanism, eight consecutive images are automatically shot while shifting the sensor. T
"These eight images are synthesized into a single image by the new Venus Engine, which boasts high-speed signal processing."
Panasonic reckons this mode is ideal for taking natural landscapes or fine art objects with delicate details.
The Panasonic Lumix S1R was first announced at Photokina 2018 and is a full frame mirrorless camera that features a 47MP sensor, 4K resolution, double card slots, dual image stabilisation and 3-way tiltable LCD screen.
The Panasonic S1 offers up a 24-megapixel sensor as well as the other features that can be found on the Panasonic SR1.
These cameras are partnering with Leica for the lenses, as part of the L Mount Alliance, This makes a lot of sense, as trying to launch another proprietary lens system would have been tough for Panasonic.
At launch, there will be three lenses: 50mm f/1.4 prime, 25-105mm standard zoom (aperture to be confirmed), 70-200mm telephoto zoom (aperture to be confirmed).
Although pricing is still not confirmed, the launch of the Panasonic SR1 and Panasonic S1 in March, alongside the new features, means these will be two of the most anticipated cameras of 2019 and surely will be up there with the best mirrorless cameras out at the moment.
