The GH5s is finally in Stock and shipping in Europe. It’s in Stock in many places like for example Amazon.de or Amazon UK. It will be in Stock on Feb 5 in USA via BHphoto, Adorama, Amazon, FocusCamera and Panasonic.
There is also a new review at Photographyblog:
While we can certainly understand the logic behind this design decision, it’s certainly going to put off a lot of would-be purchasers who’ve previously enjoyed the many benefits that in-camera IBIS offers, for both video and stills alike. If IBIS isn’t a deal-breaker, then the many improvements that the GH5S offers for video compared to the GH5 are well worth the slight hike in the asking price, especially as V-Log is now included in-camera, rather than being another expense as with the GH5.
In summary, the Lumix GH5S rounds out Panasonic’s flagship camera line-up, joining the stills-focused G9 and hybrid GH5, with all three being excellent cameras that do what they do very well.
