Panasonic is  going to announce the full S1H specs on August 27. A source at L-rumors.com spilled out his info:

• it has IBIS (up to 6 stop)
• cooling fan  to allow for unlimited video recording
• ‘24,2MP sensor
• HFR sound recording

The officially Panasonic unveiled specs are:

• 6K 3:2 capture at 24p
• 16:9 5.9K capture at up to 30p
• ‘Multi aspect’ recording including anamorphic 4:3 capture
• 10-bit DCI and UHD 4K capture at up to 60p
• Unlimited recording times
• 14+ stop V-Log/V-Gamut capture LR
• Color reproduction to match Cinema VariCam series

And he also said this about the updated  S lens roadmap:

1) Panasonic will announce the new 24-70mm f/2.8and 70-200mm f/2,8 in a month or so,
2) 16-35 f/4.0 end of this year.
3) Panasonic will  announce seven new S lenses in 2020!

So far Panasonic seems  to have failed to make meaningful sales of their  new  system (at least that ‘s  what big store owners tell me). That’s why Panasonic US greatly reduced the price of the two S cameras:

$700 off on the Panasonic S1R at Amazon, Adorama and BHphoto.
$300 off on the Panasonic S1 at Amazon, Adorama and BHphoto.

Today w e spotted the third Fuji camera registration in Asia. We now  have three Sony mirrorless cameras and  three Fuji cameras that will be announced within the next couple of months:

Sony  should announce the new A6200 and A6700 on August 29 and the A7sIII sometimes in September/October
Fuji will soon announce the X-PRO3 but it’s still unclear what the other cameras might be.
