Preview: External Power Solution for the Blackmagic Pocket Cinema Camera 4K

External Power BMPCC 4K
Let’s look at this upcoming Hawk-Woods external powering solution for the BMPCC 4K.

As much as we love what we’re seeing from the Blackmagic Pocket Cinema Camera 4K here at No Film School, like most interested parties, we’ve been keeping our eyes out for some external power solutions for the ol’ BMPCC4K.

For many shooters, it was big news when Tilta announced its first modular camera cage for the BMPCC4K. While the camera is a great offering (especially with how it stacks up with other mirrorless cameras near its price point), concerns about its internal battery life have been one of the few, but biggest, qualms about it.

So, let’s take a look a preview look at this upcoming Hawk-Woods external powering option for the Blackmagic Pocket Cinema Camera 4K.

The BMPCC 4K Canon LP-E6 Batteries

As powerful as the Blackmagic Pocket Cinema Camera 4K is, it does appear that the designers had to make some sacrifices. Working natively with Canon LP-E6 batteries is one of those sacrifices. At best you’re looking at one hour of regular shooting with each battery. Which is exactly why adapters like the ones below are highly considerable.

The first mount option (and smaller of the two) is the Hawk-Woods DV-BM4 which allows for use of Sony NP-F style batteries on the BMPCC 4K. This DV-BM4 mount connects ontop of the camera (or on your camera cage) via a 1/4-20” thread. It has a 12V regulator built-in to deliver 12V through the DC connection.

Price: TBA

Hawk-Woods LR-12 Dummy Battery

The other option previewed by Hawk-Woods is the LR-12 for larger V-mount or Gold-mount batteries. The LR-12 uses a dummy LP-E6 battery with a 12V regulator through a D-Tap connection to deliver 8.4V by way of the LP-E6 dummy battery.

Price: $98

That big battery sitting atop a camera is the silliest, least ergonomic solution I can think of. Two words for you: "Battery. Grip."

Oh dear, oh dear. Why camera accessories ae so dumb. This is ludicrous. From the top of my head I can think of few better solutions. Similar to phot one battery grip with build in front and back rail mount to support additional gear like flow focus, matte box etc. some nato rail from left and right, two mount holes from the bottom to make the plate solid. Few others mounting points for additional accessories. It should also have some left side part that will fit to the ports part of the camera and provide lock for all the ports. It would be cool if the grip have similar in style to angelbird dock for t5 ssd. Just a hole with usbc male at the end to slide and secure the drive. All at the botom so weight distribution will be proper. I wish I could have time and resources to design such things. It would make a life of a filmmakers much easier.

If I wanted a DIY power solution I would do DIM.

Mounting on top is a no-no. This needs a rod solution, and it needs more available ports to also power accesories, that will be the competition in 2018/2019.

Honestly, I have no clue why BMD itself hasn't produced an official battery grip for this thing, with it's removable battery door. I think this type of design is the way to go in terms of portability and handheld gimbals.

However, if you're near a power source, and not using a gimbal plug this baby in. Cheapest solution. No use needlessly running down a battery.

It seems that several people have spotted a gap in the market.
