Since it's possible to take a picture in cine mode, you could put the camera on cine and make the shot without the focus box

Ahh, already thought of that, but only 16:9 in Cine, no 3:2. Also, I'm not sure that it captures a raw of just a JPEG? I'm on a trip and didn't bring my laptop - can someone confirm?

They announced this week three very affordable L mount lenses - a 16mm, a 30mm and a 56mm?

The 30mm is definitely on my shopping list.

Yeah, I have the 30mm 1.4 EF (I know its different) which actually covers fullframe in 16:9 but I'm looking for fullframe compact primes in the style of the 45mm which is fantastic :) reminds me of voigtlanders with modern functionality. Otherwise my favorite lenses are the Sigma 20/40 and 50-100 (none are compact)

Also, no IOS app? Even traditionalist Leica has a phone app you can quickly link to your camera. It's handy to upload a few pics for friends or Instagram when traveling.

The fp has neither WiFi nor Bluetooth... So there's really no way for a mobile app to talk to the camera.

Are they taking request for the next firmware?

One major feature I would really like to see is custom Frame guides,
where you type in your desired aspect ratio.

And a "1:1 mode", so for example the 1080p reads the around Super 16 area
(you can already do this for the 4K)

The other is of course more resolution options,

I'm not sure how hard it is to add new resolutions but at least a few would be nice.
Something like: 
DCI 2K at up to 96 FPS(if 100 isn't possible)
Several 60 FPS resolution with different vertical crops
So something like 2.8K at 17:9(DCI), 
2.9K at 2:1, 
3K at 2.2:1, and 
3.15K at 2.4:1
If it isn't so hard maybe a similar thing with 48 FPS

A big part of what in my mind makes a Cinema camera,
is resolutions that aren't exactly standard but use the camera to there fullest potential.
(of course if they figure out 4K60 it would be great,
but I'm not sure if they can find enough processing power for that,
and this would at least be something better than 1080p)

Which camera is the framegrab from?

In my experience it isn't usually the lack of OLPF causing the moire in video mode, but sensor readout and sampling method.

Like a downsample from 6K to 4K.

If this frame was from a full res 6K RAW photo, I doubt the moire would be there, even with lack of OLPF.

I know everyone here only shoots raw, but MOV files from the fp have a lot of potential, if not for the moire issues. It is *bad* in real-world usage, especially with foliage or any fine pattern. It disappears COMPLETELY when shooting MOV with the new Color Off mode, so I really believe it is mostly an issue with sharpening being applied in-camera. I thought it may also have been the lack of OLPF, but I can't seem to provoke any artifacts whatsoever when using Color Off, so I'm almost positive it's a sharpening issue.

I'm also wondering if sigma is doing something weird with sharpening.
They do seem to readout the full 6K of the sensor, 
because of the 21ms of rolling shutter, but then the DSP seems to
Downsample the 6K into a 4K Bayer pattern.
(Unless you enable Super 35 Mode, where it does a 1:1 Readout)
The result seems to be different from Sony or Pannasonic, who use similar tech.

But the image ends up losing details, 
having more problems with False color artifacts and more Moire.(On the Sigma)

Slashcam mentioned it in there review, which I think is only in german.
Where they noticed artifacts, which didn't show up in the comparison with the
Pannasonic S1.

I'm not sure if I can link the article.

Maybe it is a Hardware issue with the DSP, or maybe it isn't and it can be fixed
with a firmware update and they just didn't fine tune it yet.

Maybe they are already working on it, because of what you said, in the
Slashcam Review, the MOV mode had even worse Artifacts(which might be because 
of the older firmware.)

Here are 3 files,

4k CDNG, looks great,  I embedded a png conversion here to see the preview
https://www.dropbox.com/s/ys0f0ah6cdgi3nc/A001_067_20200629_000013.DNG?dl=0

4k MOV with color mode off, looks allright
https://www.dropbox.com/s/8l2uayciee82v3e/A001_066_20200629.MOV?dl=0

And 100 fps 1080 CDNG, looks horrible
https://www.dropbox.com/s/vzb6z3u96j0huv2/A001_071_20200629_000021.DNG?dl=0

The 100 fps has really strong aliasing and I won't be using it for that reason.
