I don't know if a future firmware can fix that?

Never expose based on your screen brightness, that’s what tools like the histogram and false color are for..

USB control now seems to work with the Ronin S running V2.4.1.30 firmware and the BMPCC4K V7.3.
Last time I tried it with the old camera firmware, communication would fail as soon as I turned the Ronin S focus wheel. Now seems to work controlling the focus on an Olympus 12-100 IS Pro. The only problem I've seen so far is that as soon as turn the focus wheel after powering on the camera, the focus initially moves to closest focus. The Ronin S rear record button also works.
I'll try it for a while and see how reliable it is

Has BMD said officially that there is going to be an update for the BMPCC 4k fixing the mount compatibility issues and peaking? Or are we waiting for an update that will never come?

I don’t believe they’ve made any commitment, but I suspect we shall see an improvement in a timely update.

The one issue that affects my manual camera is the difference in the behaviour of focus peaking coloured lines. I used to use Red Medium and that still can work if you have the time in a personal project or test, but now Green Medium is a better choice and generally the High Range will be what is most commonly used on a client shoot. If “Orange is the New Black,” then Green High is the new Red Medium.

And I reiterate, never shoot ISO 1000. As you know, that fills all low lit areas that are starved for light with dancing false peaking dots. My recommendation for the low range is between 200-400 ISO and the high range is between 1250-3200 ISO. ISO 1600 is also very good and likely what I’ll use in judging an image when ISO 3200 isn’t needed.

Many images without significant action will look great in 360 degrees shutter angle rather than go to a higher ISO. For example, 400 ISO with 360 shutter angle might often look better than 800 ISO. I’ve done that for theatrical shoots. Maybe I’m a dreamer but I like that look on stage although not appropriate when recording BMX bikes.

These suggestions don’t always maximize your dynamic range so carefully use as you monitor channel clipping and false colour.

I'm not sure what "timely update" is if they have not made any commitment. I have a shoot next month and it would have been nice to get my camera with a stable 7.3.x. I'm not holding my breathe and will not update yet.

ATM we don't even know if there really need to ..

* USB control: I didn't dig into it since I have no hw to test, but it might just be that the gimbals are at fault, not being USB compliant. Sometime manufacturer make assumptions/take shortcuts in the implementation and it could be that some assumptions that DJI/Others made in the past are no longer correct with the new fw.

* MFT speedbooster: Again ... hard to tell if the current speedbooster firmware are fully MFT compliant and the bmpcc is sending invalid message, or if they took shortcuts that end up incompatible with an updated (but still mft compliant) implementation.

* Native MFT lenses issues: That one seems more likely where they are actually doing something wrong ... given some lens work after being replaced, it looks to me like some reset issue which might be why it got missed. It's not uncommon to have test systems that only test compliance of the messages but don't replicate exactly the startup sequence and so that gets overlooked.

FYI:

On my Pocket 4K (purchased Jan. 2019), with the Panasonic Lumix 25mm f1.7 model H-H025 lens (latest firmware 1.1) I can reproduce the following issue ...

With camera firmware 7.3 installed, I created the following 2 Presets (new from scratch):

Preset 1: Set lens f-stop to f1.7. BRAW Constant Quality 8:1 HD 1920x1080, 23.98 fps, HFR [On], Off-speed frame rate 120 fps. Save Preset.

Preset 2: Set lens f-stop to f2.8. BRAW Constant Quality 8:1 UHD 3840x2160, 23.98 fps, HFR [Off]. Save Preset.

When I switch between these 2 Presets, either:

- The lens' iris begins "clattering" (rapid clicking noise) continuously, and the camera must be powered-off to stop it.
- Or, the Iris status text at the top of the monitor is blank (no aperture value is displayed).

In either case, after I power cycle the camera, the Iris status text is displayed correctly. Other than this specific issue, my Lumix 25mm f1.7 lens works fine with firmware 7.3.

Under firmware 6.9.6, Presets created new from scratch as described above don't have any issues with this lens.

Also, my other 2 lenses (Olympus 12-40mm f2.8, and Lumix 45-175mm f4.0-5.6) don't have any issues under firmware 6.9.6 or 7.3, and these 2 test Presets also work fine with these lenses. Of course, neither of these other 2 lenses can open their aperture as wide as f1.7.
