Blackmagic Pocket Cinema Camera 4K

That's weird, because I definitely am. Are you shooting at the full sensor width? I'll get some screen caps later today :)

Also my comment about full frame was in reference to Emanuel saying the lens is usable at full frame except for the wide end while my experience is that that's not really true.

Messing around with my external monitor and looking at the scopes I can see that the zebras are linked to the red channel so all the more reason to make sure you WB correctly to avoid clipped highlights if you are using the zebras to ETTR. The GH5 along with many other cameras have the zebras linked to the green channel. Maybe BM want to avoid the user clipping skin tones above all else? Never understood why manufacturers need to just link zebras to a single channel and not have it work when any channel clips????

I've saved my LUT as .cube, like the others I've used, and even saved it in different ways. First just with the burger menu in Lumetri, then using Red Giant's LUT Buddy.

As others noted, the camera accepts either 17^3 size cubes, or 33^3 size cubes. Yours is 16^3. I've converted your LUT to 17^3 using Lattice and this should work.

Custom_Made_17.cube

FYI, i would be careful with your LUT as you can see from the cube visualization there an odd gap at the bottom and the curves are not overly smooth (though I've seen much worse curves).

Zebras are currently based on Luma or the Y channel of YCbCr (as it has been since the first BMCC).

I can't view Luma on a a display and most NLE's work in an RGB working space. Also what about RAW capture which is not YUV? YUV is just the codec colour recording system for ProRes etc.

Historically (not that we've made cameras THAT long) we've always converted internally to YUV/YCbCr no matter the codec for SDI output etc. It's then convenient and easier on resources to do image statistics on just luma for zebras/false colour and that has not changed. RGB would be more ideal, yes. Personally I always set zebras to 95% for some slight headroom (even before I worked for the company and learnt how it worked) and after i joined and we added false colour, the "red" (highlight clipping) on false colour is actually at 95% for the same reason.

Thanks @CaptainHook - the lut is only for in camera previews - I’ll grade from scratch each time. 

Does anyone know if there's a way -without cutting - to take off the flaps on the side? I remember Grant Petty took one off at NAB, but that looked like an accident. 

Also, Bloom has a loupe on his P4K.

Thanks for that clarification and I'll set my Zebras accordingly.

For people getting their hopes up, this is slightly misleading. My experience has been the following:

The 18-35 will vignette even on a .71x ('ultra') speedbooster until about 20mm in DCI 4K (only barely and not worth mentioning in Ultra HD). It's sort of usable but the vignette is definitely there across the whole left and right side and it's relatively severe.

It will basically be unusable on full frame on my A7RII until 35mm, at which point you might as well use the lighter, better, brighter 35mm 1.4 ART.

Not seen any problem with my Viltrox .71 and yes it will be unusable on full frame as it's an APS-C lens.

Just checked now (without the 1:2.40 frame guides) and yes there is a very slight corner shading wide open at the wide end but I wouldn't call it a problem and nothing that can't be fixed in the grade. Maybe on the Metabones it's different though?

 

These are tests conducted on Sigma with a XL version where is (in the comments section) explicitly written there's no vignetting from about 22-24mm on going along his GH5 for that setup, obviously:

 

And here is one where the same user tests tap-to-focus feature on the same camera coupled to the same focal reducer to those who think it might not be possible to go with AF on P4K (touchscreen focus is an autofocus feature BTW, whether you use it or not ; ) 

 

On the other hand, here are these samples which follow your feeling @seanzzxx -- very welcome to the discussion BTW (part II):

Here's a 3rd one which proves in the real world the results may vary from that 23-25mm (to stand Daniel's 22-24mm statement) mark though (on a 5DII now) -- count on some distortion anyways:

It's a shame you lose audio inputs with the side handle though, you can see in one of the images it's blocking the 3.5mm jack, so XLR must be the same.

That V-mount baseplate looks great though. 

Very interesting and holistic approach, but if they block the audio inputs, then they negate one very important advantage (for me).
