Panasonic GH5S Interview – Panasonic’s Head of Imaging Yosuke Yamane-san

An interview with Yosuke Yamane-san, the head of imaging at Panasonic, and a key person behind the newly announced Panasonic GH5S about the new camera and beyond.

If the English subtitles do not appear automatically, please press the CC button on YouTube’s player on the downside right corner.

It was late November. Osaka’s sky was very grey and Panasonic’s headquarter building couldn’t have looked gloomier from the outside – yet the people inside were very warm and welcoming to me. After spending several hours with the team of engineers who were actually behind the development of the new GH5S as well as the marketing team, I met with Yosuke Yamane-san, the division president, to conduct my interview. In his previous duty, Yamane-san was in charge on the development of the original GH5 and Panasonic’s EVA1. Now after some internal restructuring, the GH5S is his new baby.

In the time we spent together, I learned more about what led to develop the new camera, why some components were removed, what to look for with future developments and A LOT more.

I hope you will find this interview informative. Also, if you are interested in the new Panasonic GH5S, please take a look at our previous articles: Panasonic GH5S Video Hands-On – Highlights of the New Camera and Panasonic GH5S Footage – Shooting a Mini Documentary  Nino’s low-light comparison between the GH5S and the GH5 will be posted later today.

Below is a rundown of my questions and the time in the video to find them:

0:20 – Where does the new GH5S leave the GH5?
2:30 – Will you consider offering an upgrade plan for GH5 owners?
3:53 – Any Internal concerns that the GH5S will cannibalise the EVA1 sales?
5:18 – Why did you decide to introduce an enhanced camera model?
6:34 – Why was the body IS removed from the GH5S?
7:30- Were any autofocus improvements done for the new camera?
8:15 – What is the future of the Panasonic GH camera line?

If you have additional questions to Panasonic in regards to the new camera, please share them with us in the comment section. We will do our best to get some response to them.

Seems I need to polish my japanese a bit to understand what he’s saying ;)

Philipp Gärtig

Interesting informations.
But somehow this interview feels staged/unorganic… More like pre-defined questions from panasonic than from the C5D crew.

Clayton Moore

I’d guess it’s hard to do an totally organic feeling interview when you have a language deal that needs translation – thats what occurred to me.

You ask a question in English, If Yosuke Yamane-san does not speak engl then he has to wait for the translation, then he replies in Japanese and if Johnnie does not understand Japanese, he has to wait for the translation before he replies back and so forth. Not a particularly organic rhythm for sure. But staged …. ??

Clayton Moore

Thats was great, thanks for getting this interview. I found his comment about releasing a firmware upgrade for the GH5 (if required) an interesting comment. It begs the question what an upgrade would do and given physical limitations what it would be capable of doing. If a firmware upgrade for the GH5 improved both auto focus and highlights even more that would be good (just those two things).

I saw another interview with Panasonic’s Sean Robinson where they discussed in more detail the lack of IBIS in the GH5s.

Thanks again Johnnie this was very interesting.


Me too and I think a GH5 firmware update is required.

I know most will want the Continuous Autofocus improvements from the G9 and GH5s, as minor as they are. I would like the updated color science of those two cameras as well as the supposed half stop Dynamic Range improvement on the G9 and DCI 4k60 from the GH5s.

These updated would help match footage and I assume are software tweaks that the GH5 should have no issue supporting.

Clayton Moore

Yep Peter Kent,……. as a one man show myself, having a more responsive and accurate autofocus would be just what the Dr ordered. I read a review that said the color tonality of GH5 and GH5s were identical.
I would like to see a side by side image comparison shot in full light and see for myself. Id bet that a firmware update has already been built or in the process of being built even before the GH5s release.
