Blackmagic Pocket Cinema Camera 4K

The likely achilles heel of the Pocket 4K IMHO are the prominently exposed ventilation slots on the lens turret, even on the upper side of the camera. I means that the camera (aside from not being weather-sealed in any way) should never be used in any rainy/humid or dusty environment. - Anything that lands on the camera and travels through these slots will end up on the sensor.

Andrew already said it's a patented water cooling system.

I agree with him, in the photography still world the technical performance has plateaued out, with only incremental improvements now. 

When will we reach this in the video world?

I reckon the BMPCC4K could be the beginning of the end. 

Nah, not until GS & on-sensor ND hits. And maybe a Foveon-style thrown in to boot.  But all that technology exists, along with CFexpress to record it on (even 8K raw). Also DPAF. The problem is getting all that in a camera from the same manufacturer. Ugh.

@IronFilm That's a bold statement. Fanboy, not?

Because with 4K 60fps raw, and even greater HD slow motion, and pretty high DR and good lowlight, what really is left? 

Of course just like the folks in the stills world there is a never ending list of "more" wanted!
 

But I reckon just like the stills world we might get soon to point we can worry less about the technical quality of the image, and more about everything else. (such as ergonomics, or having built in NDs, I/O options, TC, wireless, or focus tracking, etc)

@jonpais, are you familiar with Poe's law? Irony (often) doesn't work on the Internet, and in this case I (and potentially) other completely misunderstood your reply, until I dug into Andrew's recent postings and realized that you are referring to this one here: 

So, just for clarification, the BMPCC4K doesn't have a water cooling system (as it is actually exists for PCs).  Humidity and dust can travel into the camera/onto the sensor through the prominently exposed fans.

There's plenty left, @IronFilm . Many need IBIS for their work. Many need eye detection. Many need reliable autofocus. Many need good weather sealing. Anamorphic de-squeeze. A tilting screen. Wifi. Smaller file sizes. The full frame look. Any number of things. There is no camera to rule them all - never was, never will be.

Thought it was pretty clear. Next time I'll provide clarification by way of smiley faces.

Watch his video, this is exactly his point, it is all these non-sensor / non-codec stuff which people need. But essentially the days of pixel peeping might soon be "over" (like it is in the stills world already, or so he claims).

I'm not seeing it (the end of pixel peeping days, that is). You really talk like a fanboy, and we haven't even seen footage from the camera yet. And while I very well might buy it, because I think it's probably the cat's pajamas, and I happen to like the people at BMD, I'm not about to drool over a camera that won't be released for another five or six months. Outside of a handful of cool heads, this thread is becoming an echo chamber. Can't even make a joke without @cantsin getting all offended.

FWIW, @cantsin, as you are now well aware, I already voiced my concern about the vents, and Andrew made a joke about it. I didn't take offense like you.

When this thing ships, what will you also buy with it?

I notice it doesn't come with a battery, so this is my list:

2x battery ------- I already have 2 so 4 should give me a good start

XLR cable ------- I think these come in packs of 2, but spares are nice

128gb SD card OR C.Fast ------- I'll be mostly shooting ProRes, so SD is more likely, but then again buy nice or buy twice, C.Fast can handle everything, SD might struggle with RAW.

128gb USB-C thumb ------- for those times when my main card is full

I’m looking at a Samsung 500Gb SSD drive but will wait for advice as to whether this is preferable to cFast cards. Fortunately I’ve got several batteries (micro and VAs use them) so that’s one less thing. 

Presumably a cage of some sort will emerge. Yes it possibly defeats the purpose but it’ll look good. (And possibly prevent the camera rotating on a quick release as it’s only got the single screw hole I think?)

For people asking about the stills function.

This is just as the Ursa Mini Pro. Its a frame grab. I think they are marketing this WAY wrong. People think it take stills.. well.. no. It grabs a frame or the live video feed it produces from the sensor. Like a video for 1 frame what ever settings your are on. The format is DNG which you can convert to whatever you want afterwards. As it is a frame grab it will be at the resoultion you have choosen in-camera. So for 4K DCI it is 4096 x 2160 = 8.8mp (max).

I would not buy this for taking stills - unless you are a cinema guy and don't experct a "regular" stills camera as there is no dedicated stills functions and no mechanical shutter. But for taking a BTS frame grab its fine.

--- Monitor ---

The monitor is the same as the one found on their Ursa Mini 4K and 4.6K (not pro 4"). So expect what you get from that and not like 1000 nits. I think it was Stuart from BMD who said it - as a source.

I wonder if you could use USB-C as a monitoring output. It obviously sends the picture out to record to thumbdrives so what about a USB monitor?

No. They used the knowlegde gained when they created the SSD recorder for the Ursa Mini. On the Ursa Mini when using the SSD recorder it sends a data signal out the SDI and onto the SSD. Its is not a video feed. It is data.. Like a USB connection. So thats what they put into the BMPCC4K. So no USB external monitor unless they develop something for this. Its is only used for firmware update, powering/charging and external recording to a USB source (can be anything from a thump drive to a RAID array).

@cantsin From what I've read those vent slots, and what's behind them, is completely sealed of from any internal parts of the camera. Hopefully JB might come on board in the near future and explain a few things.

I much prefer the build of my Micro rather than the build of my GH4.

That's a bit like comparing apples to oranges, isn't it? I mean, the GH4 is a camera that you could rig out and shoot like a true cinema camera, while the Micro is like a super Go Pro on steroids with the ability to extract 13 stops of dynamic range. The ergos are also a bit tricky, with the side buttons all crowded together and flush to the body, while the GH4's larger, chunkier controls are easier to use, especially if you're wearing gloves. In what way is the build quality of the Micro better than the GH4?

For anyone who's going to nitpick, I realize the Micro is not the same as a Go Pro.

If its anything like it was when the first version was released, it'll be rig mania for a while with people pimping them out.

Though I do have a soft spot for these two.

I still have the Z Finder, going to stick it on top and voila, tilting, twisting, spinning monitor for those handheld shots. Expose and get it looking right on the BM screen and then compose and focus via the Z Finder. It'll also give me that extra point of contact for the handheld work. 

Thinking about it, if you can turn off the BM monitor, I might be able to squeeze another few minutes out of the battery.
