I still got no 100% confirmed info about the gear that will be announced by Panasonic on October 8th. But I away a crazy amount of different rumored gear floating around the web. So I am giving you this roundup witht he wanring that this is all completely unconfirmed as of now:

Source 1 (Xitek)

Triple native ISO 640/2500/10000

The level of detail in the LEAKED specs has definitely reached a new level, so stay tuned for more updates

Source 2:

S1Hii / S2H
Stacked sensor like R3/Z8 sensor but custom designed by Sony.
6k 120p
4k 120p oversampled from 6k.
Vnd
Fans
Triple base iso
Anamorphic support
Incredible ibis improvements DJI gimbal like
Low rolling shutter under 10 ms
Ai tracking and super fast and precise autofocus
Price still debating however internal price is aggressive 2899$ so under Z8 since sensor is not 45 mp.
At 2899$ it will give Panasonic +5% market share instant and sit near Nikon in 3rd place.

And there is also a S5R rumor (Weibo):

SSS enters active period,
P home may start four Bayer 61M BSI video bottom.

first poison a mouthful of milk:

LUMIX S5R

Video Specifications:
8K FF 16:9 30fps 25ms Oversampling

5K S35 4:3 48fps 20ms oversampling
5K S35 16:9 60fps 15ms oversampling

Source 4 about a possible S1RII:

S1Rii/S2R
Same as Leica Sl3 but 3000$ to compete with Sony A7VR camera. Same aggressive pricing for market share.

It’s highly likely that Panasonic will be making a big product announcement on October 8th. But I have no confirmation yet about WHAT exactly will be announced. So I will now share two rumors that I have received from new sources. That means I don’t know if these are true or false…. but I hope that soon other sources will contact me via this contact box or via lrumorscameras@gmail.com to share more details.

Source 1:

S1Rii and S1Hii both getting announced on the 8th
New firmware to support Lab app for older cameras and improving some features including AF tracking and Ibis

Source 2:

About the S5D it’s really weird, we asked to Panasonic whats going on with this camera and they told us its actually only a S5 mark I upgrade.

I would be positively surprise if Source 1 would be spot on!

Image on top show the current S5

An unknown source shared this rumor that to me sounds weird and probably untrue:

Lumix S5D next camera, upgrade of S5 Mark I, no Phase detection AF, 1599€ with kit lens 8 October

Make no sense to me at all and my bet is that this is BS…
