Blackmagic Pocket Cinema Camera 4K

Recommended Posts

I have noticed that when changing out a battery, the used battery is quite warm when ejecting it.

I'm wondering if all these battery compartment issues are more to do with cheap batteries not being able to handle the warmth without expanding beyond spec. Any cases of batteries getting stuck with the BMD or genuine Canon batteries?

If some batteries are expanding enough to jam, then maybe they should be avoided, poor design.  Or maybe the battery compartment is designed just too snugly?

I know there is no adapter to mount my Sony lens on it, so any recommandations about which lenses I should get to start ?

Get the classic Sigma 18-35mm f1.8 with a viltrox nikon focal reducer.

I've never heard of an E mount to MFT mount adapter. Isn't this impossible?

No. But the reverse is possible. But you'd only use it with fully manual lenses.

Well, strangely, I just put all my batteries in (not at the same time)

A pity that isn't possible! 😉 All day long battery life.

Remove a couple more wheels and you'll have yourself a motorbike!

BM have shot themselves in the foot a bit by not getting the power accessories in place when they shipped the camera.

 The list their own battery for £35 and, whilst that is still a lot more than other 3rd party batteries, I think that would be by far the best way to go as at least you know you are using the same battery they design for and test with but I can't actually see it at any of their UK dealers. Similarly, it doesn't help that the official cable pack that would enable it be powered externally doesn't seem available anywhere either. 

 

It is very disappointing that BMD didn't use a more common industry standard for external powering. Which is strange, as normally BMD tries to use something commonly available. 

Heck, even if they'd gone with LEMO (as much I hate them being a common industry standard.... gah) that would have been much better!

Anyway, it isn't the end of the world, as Wooden Camera have in stock and are shipping right now a D-Tap cable for the BMPCC4K:

Blackmagic themselves also sell a power cable kit that is cheaper than the Wooden Camera cable and gives you three cables rather than one.

Stupid or genius?

No (little) vignette until around f8.

I plan on taking the camera for a walk with a few of my favorite lenses. I’ll take this little chap along and share some clips. 

Let me know if you’d like anything specific tested out.

Wooden Camera is for those who are impatient. 

I think the really impatient ones will be cutting the mains cable in half then attaching a barrel connector to the harvested side so they can attach it to the ubiquitous £10 Small Rig Sony F battery plate ;)

Any news about the soft edges when using wide lenses like the Laowa 7.5? I was following a thread about this on bmcuser but I think it got removed?

No, I think its still there, it just seemed to die.  I have been waiting for the update on that.  Did he have a faulty camera? Did the problem go away once he stopped down further?  I may need to bump it, because that seemed a serious issue.

@TurboRat and @MattH - I don't have that lens, but I have the Canon 10mm that I've hacked (literally) to work with the Viltrox speedbooster. I imagine this give a similar field of view - although it will be slightly narrower. I'll happily do some tests for you, but can only get to f3.5ish with the booster.

If that's helpful, let me know what formats you'd want tested and I'll upload some stuff.

For a quick sample, here's a grab I just took at it's widest. Handy button that frame grab one 😄
