I bought it over the BMPCC4k at the time because it was actually cheaper (rare), I already had the BMVA 7” and if needed it could be pressed into service as a stills cam, something the P4k cannot do.
I would not replace it as it is in a role it was designed for and does it perfectly well. B-Raw is my maximum video quality end goal, 4k/50 my maximum in that space, so the lure of ProRes Raw is of no interest (V-Log is enough for most projects, ProRes is an option, B-Raw is better again).
The EM1.2 (x2), the long lens half of my day kit (with a G9) are old, beaten up, occasionally “twitchy”, but reliable enough for most jobs. The AF is plenty for sports with better lenses, the low light decent enough, they are solid without being exceptional these days, but solid gets most jobs done.
To be honest I do not really treat them any differently to the EM1x’s when I am working, but I find them slightly “laggy” compared to the X’s from off to ready to shoot, but they are still faster than most Panasonics.
If these were my high water mark, I would be ok. The demise of one will likely mean regularly using a spare EM1x as a day cam, but both would mean chasing up another new gen stills cam like an OM1 or second G9II.
The G9 (x2) is the wide angle day cam in partnership with above. These are maybe slightly better than the EM1.2’s in many ways, closer the the EM1x in low light, handling and general feel, but the DFD focussing makes for an odd experience with sports (no Pana long lenses), and video AF is slightly unreliable.
Video is lovely, if limited to non-Log profiles (I like Standard), although I have not looked closely into their HDMI output to the BMVA 12g (which they do). Maybe HLG or Cine-D in ProRes would be worth a look?
The only thing that could be improved here would be hybrid video, and video/sports AF, i.e. a G9II. I will not replace a worn out one with the same, but I will miss them.
EM10.2 (x2) the “shutter savers” are my usual third cameras, because it is easier and faster to change a camera than a lens and these are sure footed enough to use as short telephoto snipers.
I usually have one in my bag with a lens I might need, like the 9mm or a 45mm. Both have twitchy rear screens, so I usually use them to the eye, normal for longer lenses.
When used up, they will go and I doubt I will go this way again, but who knows. They are useful, have good enough image quality to mix it with the others and run for ages per battery.

So, improvements in video are really not needed.
I do not lust after codecs I have no intention of supporting or storing (4k B-Raw at 5:1 already eats up massive amounts of storage), I have state of the art AF, stabilising and several endurance options as good as I would need (in multiple options) and basically as good as I can get. Maybe another BMVA 5” would be added as a backup and to upgrade the G9II, but then I loose it’s small size portability, so more likely a cheap BMPCC4k, freeing up the G9II for stills.
An S1mkII or GH7 bring unwanted internal ProRes Raw, have expensive card needs, give me nothing above what I need and the S1 adds possible over heating issues. The G9II matches the AF and stabe and if V-Log is enough the S5II comes close enough as well. If I feed out to a BMVA 12g, what have I really gained?
In stills, the only thing that worries me slightly is low light sport, but I may have the answer already (G9II) and nobody is complaining. I can usually use the 75 f1.8 or shorter for basketball and netball, the f2.8 zoom when needed and even occasionally an f4 lens in some venues. I fear nothing really up to ISO 6400, f2.8, 1/500th, plenty for most venues.
Full frame for very low light is tempting, the Sigma 70-200 f2.8 the best option there ($1800au), but again 24mp and the super sharp 85mm S-prime does most of what I need and I get maybe two jobs a year where it matters (most top end sports have good light, the low end ones don’t expect miracles).
The ultimate would be the S1.2 with the 100-500 (Pana) and 70-200 (Sig), but I am not getting the work to warrant it.
Shopping list options;
A second G9II for stills ($2000au+). This would give me possibly a stop better low light sports performance, the extra pixels would also allow for the f2.8 zoom to be used more and cropped.
Firmware upgrading the S5II for video ($250au). The G9II then becomes the possible hybrid option (see above) adding power to my sports kit and the S5II becomes the movement cam (which it basically could do now in V-log). The G9II is no smaller than the S5II, but the much smaller lenses are shared with the stills kit.
Adding a 70-200 Sigma to the FF kit ($2000au+). Tis gives me reach when needed for tough indoor sports, elevating my kit to match some top end shooters.
So, the answer to the question “do I need to upgrade” comes back with a soft, “when I can, if I need”, no rush.
