Blackmagic Pocket Cinema Camera 4K

Recommended Posts

Hang out on these forums more often...  People here use native lenses, speed-boosters, non-speed-booster adapters, vintage stills lenses, vintage cinema lenses, and even free-lensing of lenses! I don't remember anyone using non-camera lenses like projector or enlarger lenses, but someone probably has..

Welcome!

Personally, my m43 kit has both native and vintage lenses in it.  I do own a m42 to m43 0.7x focal reducer which I might use with a ~50mm to fill in the 80-100mm equivalent spot in my kit, but I might end up just using a 35-50mm lens without a focal reducer and therefore not end up using it at all.

The crop factor makes it a spectacular choice for longer zooms too, for sports or for wildlife.  A 135/150/200mm vintage FF lens will set you back less than dinner and a movie, and combined with a $10 dumb-adapter you get a fast, high quality and solidly built manual telephoto lens, plus because you're cropping into the lens with the sensor size you don't get all the CA and soft-focus of the corners of those lenses so they're even better than when they were new!

odd that you mention that just now.... i just bought an el nikor 63mm enlarger lens. been waiting for one of these to turn up at a reasonable price for awhile now. i guess my lens addiction is off to a good start this year😀

Nice!

There are some interesting projector lenses around, but the lack of a standard mount or adapters means they're a little too out-there for me, at least at the moment.  Plus them having no ability to stop down does limit their use in a creative sense.  Still, considering that adapting FF vintage lenses seems pretty mainstream now, they're probably where the real bargains are :)

As much as I love the IBIS on my GH5, I will say that recording prores internally would be lovely.  I'm rendering proxies for a three week trip and 350Gb of footage, it's done about a quarter and has been going for a couple of hours now and it says it has about 7 hours left..  that's an hour more than when I started!!

4K Prores Proxy has broadly similar bitrate to 4K 150Mbps or 5K 200Mbps footage and both are 10-bit!  

That person who shot that video in Prores Proxy (or was it LT?) had the right idea :)

Ninja V solves this for you...and it's a great monitor too...

I wish this  camera may create proxy videos...

You mean in addition to RAW?

If you shoot in Prores then you don't need proxies :)

My 350Gb of footage took 11 hours to render proxies.  Good thing I didn't have to go anywhere and take my laptop!

So I've seen some derision about Pocket4K regarding it crashing or behaving erratically, as well as issues with the batteries. I thought I'd share my experiences with these.

 

Short version: The battery that comes with the Pocket is utter, utter shit. Use original Canons instead and you'll see way less issues.

 

Long version:

That battery really is shit. I really can't overemphasize how shit it is.

So, for me Pocket 4K was a no-brainer because I already had a lot of it's necessities lying around - Cfast2-cards, tons of compatible batteries. So, the latter has meant that I've been able to run the Pocket with not just the battery it comes with, but with a couple of relatively fresh (2-year old) OG Canon batteries as well as a few different off-brand ones (4-5 years old). So here's a short summary on how they have performed:

 

Original Canon LP-E6:

- No problems, can be charged in-camera or with my canon rechargers. Displays remaining battery accurately. No surprise shutoffs.

- Drains the slowest of all the batteries I've tested. Still pretty fast, but quite manageable. Usually end up using 1-2 batteries a shooting day (b-cam).

 

Off-brand LP-E6:

- Like Canon, can be charged anywhere.

- Depending on the off-brand battery, might or might not display the remaining charge accurately.

- Can go from 40% to empty in seconds. So the 0-40% range is a bit of a wild card. May be due to inaccurate charge display or these might just be plain old and tired.

- Drains faster than the Canon.

 

The Blackmagic... thing:

- Can't be charged with Canon chargers, causes them to enter fault mode (continuous blinking.) Occurs with both my chargers. Googling the issue has led me to find others with same experiences. Can only be charged through the camera.

- Charge display is just whatever. Can go from over half-full to camera shutdown in seconds.

- Sometimes works like an off-brand one. At worst, from full charge, lasted me around 3 minutes of recording before the first shutdown.

- And notice the above? "First shutdown"? That was today. So, apparently the blackmagic battery is prone to just dying momentarily when there's a large power drain present. So what happened was, I set the camera to record, with battery at around 75-80%, and after a few seconds the battery meter goes haywire and the camera shuts down. Then it boots up again, and the battery shows up at 75%. Guess what happens when I hit record? Rinse and repeat. That was the moment I chucked the battery. Switched to Canon originals and the rest of the day went without a hitch.

 

So, taking from this, I think some of the reported erratic behavior can be traced to the completely all over the place quality of the original battery. Having the camera reboot itself during recording is something that could be blamed on the camera if you have no way to troubleshoot and find the real culprit - which was the blackmagic battery. Maybe there are good ones too, but to stay on the safe side, I'd recommend just using it as a last resort backup at most, and sticking to Canon originals or maybe some higher-quality off-brand ones.

Thanks for this! 

Looks I will be buying original canon batteries. As charging in camera sucks.

I have also had good luck with the Wasabi batteries (https://www.amazon.com/gp/product/B01HFOJQ0I/ref=oh_aui_search_asin_title?ie=UTF8&psc=1). I have several and they all work better than the original BMPCC4K battery. They also show battery percentage. I don't have any new Canon's to test against, but these are just as good as my Canon batteries that are a year or so old.

I can't say I don't like the look of the PK4 but it is not what I think of when I think of a BMD camera. It just looks too good, too clean. A trend for sure now, but not a trend that I would like to pursue. Now for Docs, interviews yeah the PK4 would be the way to go. To me the special look Blackmagic has is gone in this camera. But times are changing and they have to change also. And the price is right. A way better overall camera than the cheaper previous stuff. I think they did well.

It will help young and old film makers learn the trade just like the original BMPCC, BMCC has. So that alone is a good thing.

It CAN be cleaner, it is not necessarily clean if you need, want or look for something else... You can have 1 million if you'll have a 10-million account. The opposite is harder to achieve on the other hand ; -)
