Lumix GH5s Proves Panasonic Not Stepping Off The Lumix Gas

Posted Jan. 8th, 2018 by Daniel J. Cox

New Lumix GH5s

Panasonic is not stepping off the Lumix gas and today announced ANOTHER new camera, but along with their move, the production of the latest hidden camera has been postponed. It’s a low light version of the GH5 which they’re calling the GH5s. This camera has been rumored for a month or two and it finally comes to light at the start of 2018 CES show in Las Vegas.


The new Lumix GH5s. A tweaked version of the GH5 for even better video capabilities.

Why another version of the GH5 you might ask? We’ll it’s simple, the GH5s is tweaked for shooting at much higher ISO’s and achieving better results for mainly video. This is not necessarily a still photographer’s camera although it will also shoot terrific still footage if you choose to do that.

One of the main differences between the GH5 and the GH5s is the S version has a much smaller megapixel sensor; in-fact, it’s about half the size of the GH5. Smaller megapixel sensors allow for much lower noise characteristics when shooting at higher ISO’s. Is 12 megapixels enough for a great image? I say it is.

I shot the Nikon D2X, a 12-megapixel camera for two years, and I’m still selling those pictures with no concerns from the editors we work with. Even more impressive is the D2H which I also shot for two years—a 4-megapixel machine—that once again no editor has ever complained about. Does this tell you 45-megapixel sensors are overhyped?


A quick comparison between the GH5 and GH5s. For a great hands on Review check out Imaging Resource.

I’m astounded at the commitment Panasonic is showing to becoming a serious contender in the world of still and moving pictures. They’ve been a major player in the video world for decades, but now they’re pulling out all the stops to dominate both. They still have a ways to go, but as fast as they’re moving, it won’t be long until they have the technology to slam the door on the need for big, heavy, expensive cameras and lenses.

I predict by this time in two years that may actually happen. All it’s going to take is one step forward in new sensor technology and we’ll have all we need for creating amazing imagery in both stills and video. All that in a package that is easy to carry, is more spontaneous, and doesn’t drain our bank account.

Keep the pedal to the metal Panasonic. You’re providing an exciting ride.

A few details of new Lumix GH5s

  • 10.2MP newly developed multi-aspect sensor provides sufficient margin to get the same angle of view in 4:3, 17:9, 16:9, and 3:2 aspect ratios.
  • World-first 4K 60/50p recording in Cinema 4K (4096 x 2160)
  • Internal 4:2:2 10-bit recording with V-Log pre-installed in camera.
  • Dual Native ISO Technology
  • The 225-area AF arrangement stays the same, but the GH5S can now focus in light levels as low as -5EV (on the GH5 it’s -4EV).
  • Max ISO 51,200
  • Time Code support
  • The Panasonic Lumix GH5s will be available from the end of January priced at £2,199/$2,499 (body only)

    I’d like to suggest a change in terminology for one part of this article for clarity and to avoid confusion:

    “…in-fact, it’s about half the size of the GH5. Smaller megapixel sensors…” probably should say, “…in-fact, it’s about half the RESOLUTION of the GH5. LOWER megapixel sensors…”

    Thanks for your continued great work!

      Oh, and I’d like to “thank” Panasonic for adding to my GAS (Gear Acquisition Syndrome) with this camera! 😉

    I have shot my first big documentary with Sony A7S and Canon 7D. The film is doing FF circuit now and i am yet to see how it performs in the big screen. Daniel how will GH5s stand when the film shot from it has to be projected in theaters in terms of resolution sharpness.

      I’m really sorry but this question I just can’t answer with authority. My guess would be that it’s going to be fine but that’s only a guess. I’ve never projected any video on to a full size movie theatre screen let alone any files from this new camera. I wished I could be more help. Well all have to wait to see what the cine guys who test gear think. EOSHD, Philip Bloom and others.

    Do you know/think that IBIS may be possible in the future with the GH5S through a firmware update? It looks like a great camera for some, but is a niche product if there is only lens stabilization available.

      There is not chance of IBIS in the future for the GH5s Mike. It’s much more than a firmware product, it involves an actual physical structure inside the camera that the sensor floats on. No chance.

    Thanks for another informative post. I trust your judgement and straight talk. Looking forward to the ride ahead,
