You can find the Switronix PB70 for Blackmagic Cinema Camera at Adorama for $299

When the Blackmagic Cinema Camera was announced at NAB many DSLR users were quite concerned by the lack of interchangeable battery and the short 1 hour run time on one charge.

In practical reality it is one of the best features.

Thanks for the review Andrew, you're really on fire with this wave of valuable content lately, keep it up!

Agree on the internal battery, it's like a laptop plugged into a wall socket, no need to worry when plugged out accidentally.

By the way, is this battery suitable for powering my GH2, or do you recommend other power solutions?

BMCC is 12-30v. GH2 is more critical and narrow when it comes to voltage and I don't know what professional external batteries can be used with it if any. There are some DIY options I've heard of over the year but I've not tried any of them. At least interchangeable GH2 batteries are very small and light to carry.

i bought a plug in adapter on Amazon for my GH2 in April. A little ghetto seeing as it's a Gh2 battery with a cord hanging out of its ass. the battery door still closes though, and the cord can disconnect about 3 inches away from the camera to the other half that plugs into the wall. i was thinking about getting an external battery like the Switronix to add some productive mass to that little bastard. Even with a Voigtlander on the front, I have had no luck getting a proper balance on any steadicam. it's too light. So aside from taping a dumbell to the cheese plate, if the adapter works, maybe this could work.

Way off track, sorry.

Andrew, I see that Redstan anamorphic clamp on there, what have you been up to, hmm?  B) 2.5K RAW-recorded anamorphic footage ought to look INSANE, I can hardly wait and almost wish I had a BMCC myself (but I've told myself I'll wait for certain things before buying any new body).

Thanks for the review Andrew. So we already have a great and affordable battery solution. Who knows something about a view finder for BMCC? I use on gh2 lcdvd viewfinder but don't know if it's posible to attach a viewfinder on BMCC.

Best regards.

can you mount this to a v lock battery plate as well? So you can use the battery plate, or mount it directly on the camera using their plates and adapters

Actually I am not sure, will check.

Just out of curiosity, how does the prores recording mode compare to raw in terms of battery life?

Hey Andrew, how do you use the PB70 with your ReWo rig? Is it possible to remove the rails mount on the bottom of the ReWo and mount the PB70 instead of the Energizer battery? I love that rig but not a fan of the energizer batteries. Also, have you considered using Tilta handles or Movcam handles with the start/stop button built in on your Rewo? Love this rig but there are a few things holding me back from making the purchase right now.
