Blackmagic Pocket Cinema Camera 4K

Recommended Posts

I've been waiting on buying a gimbal until the Ronin S is updated so the focus wheel can work with this camera - however, I just thought that since the focus on that gimbal is via the USB on the camera, and the camera then controls the focus, that likely means that adapted lenses won't be compatable... right?

If tap to focus doesn't work with a speedbooster, then chances are this 'software' follow focus also won't work. Would it then be better to get the Crane 2 as their 'hardware' / mechanical follow focus is now included for free.

Yes you'll have part of the gimbal blocking your screen, but that's far easier to work around than the Ronin's focus issues (if there are any with adapted lenses).

Or am I missing something and there's an even better solution?

The Ronin S controls focus on the other cameras using the MTP protocol over USB, so that won't be an option with the Pocket4K.

BM's own camera control protocol runs over SDI and latterly Bluetooth LE. The former isn't an option for the Pocket4K but the latter is.

The Ronin S does have Bluetooth LE (to talk to its app) so that would be a viable way to do it but BM's remote focus control isn't particularly elaborate (just near and far in 1 step increments) so even if DJI implement it then I'm not sure how well it will translate to that wheel.

Dji is supposed to release a focus motor that will allow the Ronin-s to focus virtually any camera.

Both dual native 400 and 3200 ISO coupled to ETTR and you are just fine. Have no worries anymore about it : -)

No complaints about, circumstances vary. It will also depend on your shooting style and last but not least, subjects to shoot for sure. Obviously. But, if you want to protect your highlights, you'll have enough DR room from your clean shadows to go on ETTR : -)

From the looks of it, shoot in nothing but 400 or 3200 ISO. Why even have those other ISOs available if they produce such gross looking highlights?

: ) Part of the exposure system... : D Well, reason why ETTR can save our arses ; -)

They only have gross looking highlights if you overexpose your footage by a ridiculous amount ( 3 stops in that test) as once you move off a base ISO your DR drops so clipping is inevitable. On any camera it is unwise to move off base ISO for this very reason but at least with the P4k you get dual base ISO!

Yeah but this is not the only camera that has Dual ISO. The GH5s, the Varicam, EVA1 to name a few. Surely someone on here has experience using them to hint at what to expect on the "in between" ISO's?

Single or Dual ISO the same thing happens when you move off the base/native ISO - you loose DR. Look at any DXOmark DR test graph and see DR vs ISO. The strategy with a dual ISO is ( and has been widley reported) is it's often better to go straight up to the higher base ISO than push the lower base ISO. Also in stills ( RAW) it's also a strategy to keep the ISO at base and underexpose then push the file in the RAW developer.

Not sure if it has been confirmed before but the bmpcc 0.58 speed booster works on the P4K, nice option for the 120 windowed mode 🙂

This is great news ! Did you actually try it yourself ? I was afraid the rear element of the speedbooster would hit the glass protecting the sensor !

It fits quite tightly on the P4K, which added to the drama a bit, but it seems to maintain a sharp image, will do some further testing with a variety of lenses.

Did you confirm this? I was looking at picking up the 0.64xl version. If the 0.58 really works then I will be looking at buying that instead and pair with Canon 24-105.

The 0.58 metabones won't cover the sensor unless the camera is in window mode for the 1080 120fps, so is not usable in UHD or 4K in non windowed mode, to be clear about this. But if you have one from an original pocket it can give you a wider option when windowed.

I did try this on my P4K, but I am not advocating others try this themselves 🙂
