Panasonic launches their highly anticipated LUMIX S1 & S1R full-frame mirrorless cameras

The efforts of Canon and Nikon in the full-frame mirrorless market following Sony’s monumental success with the format has caused a significant stir in the imaging industry. The competition offered by the trio and the outlook of the preexisting Canon EF and Nikon F systems has sparked conversation and caused turbulent second-hand camera market movement. Today, Panasonic joins the fray with their highly anticipated L-mount system with the Lumix S1 and S1R cameras.

In addition to the aforementioned features, the LUMIX S1 will have a paid firmware upgrade in the near future, unlocking the following features:

  • V-Log L Gamma Profile
  • 4:2:2 10-bit Internal Recording
  • 4:2:2 10-bit 50/60p HDMI-output
  • Other unannounced video features

The cameras are priced at US$2,499 (S$3,370) and US$3,699 (S$4,990) respectively and will ship on 4 April 2019. Accompanying them are three L-mount LUMIX S lenses:

  • LUMIX S Pro 50mm f/1.4 – US$2,299 (S$3,100)
  • LUMIX S 24–105mm f/4 Macro OIS – US$1,299 (S$1,750)
  • LUMIX S Pro 70–200mm f/4 OIS – US$1,699 (S$2,290)

Panasonic was a pioneer in the mirrorless interchangeable-lens camera market. Along with Olympus, they developed the Micro Four Thirds system to be a relatively open standard. The result today is a vast selection of compatible camera bodies, lenses, and accessories from more than sixteen companies, each bringing something to the table.

Utilising a similar strategy, Panasonic has adopted Leica’s L-mount. Together with Sigma, they form the L-Mount Alliance. With Leica’s existing line-up of SL lenses, Panasonic’s LUMIX S L-Mount full-frame lenses roadmap includes three more lenses in 2019 — 24–70mm f/2.8, 70–200mm f/2.8, and 16–35mm f/4. Panasonic will have 10 lenses by the end of 2020, while Leica and Sigma would each contribute 18 and 14 lenses respectively (albeit with Leica’s impractical pricing).

We understand that a spec sheet may not tell you nearly everything there is to know about a camera. Hence we’ve found an incredibly helpful video from DPReview TV highlighting of some of the features that aren’t in the spec sheet:

Engadget has reported that testing of pre-production units reveal that the contrast detect autofocusing system “seemed slower than on Panasonic’s GH5” in video mode. Panasonic claims that the performance of the deep-learning autofocusing system improves over time.
