4k bmpcc

Super strange indeed!

Which is a pity!! As I wish that statement wasn't so strange.... because if it had a flip out screen it might be a perfect camera for me and my vlog! (all there is left to add would be IBIS, as of course the vlog is handheld)

So its missing flip out screen, IBIS , doesn't have comprehensive auto focus and its still perfect for you ? Not sure what it does have for your application.
 
"URSA have it and it is nir fully functional"
You mean the one with that stupidly huge flip out? No one's talking about something like that.

"fix screen is ok and completely usable"
From one angle.

I think BMD is still conflicted over functionality vs size...as that clip of Petty so clearly points out. I'm a bit surprised the interviewer didn't say "Wait..what?"
Fixed screens are a hold-over from still cams..where one can use bracketing, adequate autofocus and post proc (inc reframinig) to allow "spray and pray" when high angle shooting, for example.

What was Kubrick thinking without an adjustable eyepiece?
 
Kubrick wasn't known for his vlogging or wedding films...

Thankfully he wasn't. But if he had the inclination he'd slap a 7.5mm Laowa lens on the camera and press the button that was conveniently put there for that purpose and that would be the end of the 'theres no articulating monitor' ***** fest.

Seams like the Micro Four Thirds system will continue to get support for a while.
 
Wish it didn't look like FisherPrice designed the outside of the chassis. Otherwise it looks like it might be good.
 
There's only so much you can do with plastic. The big heat sink behind the sensor gives it that big nose. Having a plastic shell rather than metal, that insulates rather than dissipates, doesn't help. Still, I wonder how the GH5/s get rid of the heat in such a small package. The Ursas also have very big heat sinks. Keeping that sensor temperature down keeps image noise down. BM engineers may just be doing a more conservative design than Panasonic when it comes to heat and reliability.

I think right there describes part of the cost difference between the two cameras. It isn't cheap to make a compact camera shoot 4k video and dissipate heat well with a massive amount of processing power to handle a h.264 encoding and noise reduction in camera. BMD uses a lot of engineering shortcuts to make the camera a reality and doesn't have the engineering infrastructure to make things super tiny and efficient. Nothing wrong with their approach but nobody builds a camera like this for half the price of the GH5S without some engineering compromises. BMD makes darn good cameras for what they do but they would never win an engineering award when up against a camera like the GH5.
 
That's not the heat sink behind the sensor. The sensor is at least 20mm inside the lens mount and the fins are closer to the mount...

Can you elaborate ? In a really precise engineering based way ?

being a retired mechanical designer myself....I'm of the persuasion that form follows function. And when form can also incorporate aesthetics, then it wins design awards...for good reason. I think the camera is beautiful. This camera had real designers laboring over it. They did an incredible job, if it lives up to it's specs. We've all been asking for innovation. The gh5 is a nice camera, incrementally designed using repeated lessons, and successes based on it's formulaic system. The gh5 designers simply began by copying the gh4 design. The blackmagic team however were thinking outside the box.... lucky for camera lovers around the globe. So as for innovative thinking , the bmpcc4k wins in a blink. The main problem with this camera will be ...getting one !

Being a "mechanical designer" how can you not look at this dogs breakfast and laugh.

I would ask simple design questions/specs

Can one hold and focus in a stable manner (no)

Can one monitor in the sun or off angle (no)

Do any accessory leads foul the hands or a gimbal or get broken when you put it on a bag? (All of them)

Can one get correct exposure in daylight (no)

The form runs entirely contrary to the function.
 
This is going to be embarrassing for either you or me, but here it goes.

"You mean, like my phone?"

I'm actually really curious about this, too. The big thing I always hear is "but the sensor size is smaller in a phone". My understanding here is limited, but this just doesn't make sense to me. Isn't it not about the sensor size, but rather the # of pixels being processed - which should be about equivalent (actually, less as I understand since the iPhone cameras have more pixels than the BMD cam?).

Theories are economies of scale and resources to harness power of latest ARM chips in the most efficient manner possible, regarding the entire chip and processing design... but i'm reaching past my knowledge here...

I would love a great explanation of why iPhone X can process 240fps 4K video without a hitch, among everything else is doing, on that sexy display, on a smaller battery, in a tiny form factor... and sensor size just doesn't make sense to me.

Someone.. help us understand!
 
The sensor generates heat, and that's a bigger issue with a bigger sensor. The processor also generates heat, and that's less of an issue when you use an off-the-shelf processor that does only a few things but does them very well. There are lots of processors able to put 4k video into highly compressed H.264 or even H.265 8-bit 4:2:0 files, and they're all designed for phones so they don't generate a lot of heat. If you want a pro codec, then there is no off-the-shelf processor for you, and either you make your own ASIC (extremely expensive unless you sell a zillion cameras) or use an FPGA (which is less powerful and generates more heat).
