As it was initially unveiled at Photokina last year, the Panasonic Lumix S1 and S1R cameras are their answer to the domination of larger sensors in stills and video mirrorless cameras. Is there any reason now to buy a Full Frame DSLR when mirrorless is so advanced? The only thing we can think of is to have marginally longer battery life. The mirror is on its last legs and fans better start offloading their lenses if they don’t want to mess with adapters. In the case of Panasonic however, it is not possible to use Lumix Micro 4/3 lenses on the Leica/Sigma/Panasonic Full Frame L-Mount.
The S1 and S1R will both shoot up to 180fps 1080p video with a crop that may or may not be impactful. Seems the S1R has less crop on 1080p than the video geared S1 which is an odd spec. We will have to wait for more samples and info on the HFR mode to see which of these cameras offers the best slow motion performance. From the limited samples, we can say that the quality looks very good and at least on par with the Lumix GH5 at 120fps.
