Actually two 11 bit values turns into a 22 bit value, which is then processed as 16bit lin internally, not 14bit. It’s then log encoded as a 12bit once it’s encoded into a DNG or ProRes.
Alexa is the same, but two 12bit values turned into a 24bit value then down to 16bit.
I’ve long felt bit depth is the most important part of the digital imaging chain, not resolution.

Really? Two 11 bit values turns into 12 bits actually. It can't be more precise than that.

Of course it does. It requires more processing power, which creates more heat.
No it doesn't. Pixels are pixels, the processor doesn't care how big they are.

For DPreview review/preview for the camera and their first thorough preview of the camera.
"Autofocus in video is up there with the best. Tracking and refocusing on subjectives is intuitive and reliable... besting what Canon and Sony offer"

I am looking at this:
Z7 footage starts just after about 6 minutes in. The camera is clearly having a tough time refocussing.

The proof is in the pudding. Sony claims 14 stops on A73 and that's an 8-bit codec . So yeah why get the BM P4K? we all know some companies fudge these claims, others are more conservative.Nikon is probably the later, they gave a CIPA rating of 10-15mn video battery life, yet Fro dude says " The battery read 44% at the end of our shooting which included 500 or so photos, setting up the menus as well as filming for close to 20 minutes in full frame 4k."
Battery life will depend a lot on how you have set up the camera. If you have CAF set up and running all the time for example, power drain is going to be much higher than if it is only active while shooting/focussing. The spec battery life will be for everything running all the time, basically a worst case scenario.

We’ll have to wait and see, but this camera seems to be a pretty nice hybrid. Good internal image when you need a small footprint or add a cage, a Ninja V and all the goodies when you need a higher FF output with a relatively small footprint.
Right. I had a shooting day yesterday, so I haven’t been catching up, but is the 1080p a downscale from 4K? If so, 10bit 1080p ProRes to a Ninja Star sounds pretty okay to me.
We will have to see what it is like in actual user hands. The footage shot with the release event cameras that has appeared on the web does not look all that impressive to me. AF seems dodgy and most of it looks pretty soft.

I read somewhere that you can power it using a power bank, so the 15min limit is moot. And with a power bank, overheating is far less likely, even in a small body like this.
The bit that overheats is the processor. When it does, it throttles, and no longer can do the compression, hence you stop recording. Battery has nothing to do with it.

Well if that's the case then people better be prepared to be be disappointing in the A7SIII.
Pretty unlikely that Sony will be using Nikon's processor. If they use the same processor for the A7SIII that they used in the A7III then it will not have 4K60p, but if they introduce a next gen processor then chances are it will.
11 hours ago, Danyyyel said:Thats what Dpreview said in their video about autofocus in video from someone who questioned that they said AF was better than Sony, "Yes, video tracking AF is far more usable and accurate on the Z 7 than a Sony Alpha camera (where you have to first engage 'Center Lock-on AF', an old and unintuitive algorithm)."
AF performance looks pretty crappy based on the video that has appeared so far. Unless they don't have the cameras set up properly (entirely possible) from what I could tell the camera seems slow to find new focus and often is not focusing on the proper point.

Great for the Nikon camp, should stop those looking into Sony, but i'm not as blown away by it as I thought I would. With no video line to protect not sure why the cameras are stuck at 30p. Also it's kinda of hard to go back once I started using dual card slots in my A7III. Plus they making you buy way more expensive XQD cards. There is nothing on the cameras that can't be done utilizing basic SD cards. Unless they are going to have an upgrade in the future for raw video then it's totally pointless additional expense.
Also not sold on the AF yet. Not sure how you go from abysmal video AF in your flagship DSLR D850 to class leading AF in one year for the Z series. Do like the top panel, 144Mbps bit rate and 10-Bit HDMI out but it seemed like they cut a corners to try to justify the D850's existence.
Just not seeing enough of of the Z6 that my NX1 can't already over the past 4 years. I'm sure the low light will be remarkable, but outside of that I can't really buy into it.
Hopefully they'll have a Z8 to take on the A9II with 60p, dual slots & internal 10 bit. Wouldn't mind Sony updated the A7III to 10 bit & 150Mbps as well. Not in love with the video when compared to the NX1.
Because the processor would overheat and shut down if they tried. 4K60p and 10 bit are not there for a reason, and it has nothing to do with deliberate crippling.

In camera vibration reduction carries a asterisk noting that it is the first among their ILCs (but not first among non-ILCs by implication). The P1000 also has 5 stop "in camera vibration reduction" which AFAIK is software based. If that is true then the cameras do not have real IBIS.
High speed frame rates are done at 12 bits.
Focus points are not necessarily all PD, some are CD (I am guessing most). Also, not all of them may be available outside of single point focusing.

That is what they said about the 1 series, lol, and look where those are now.

The Movie Maximum Record Time does say 29 minutes 59 seconds, but further down in the specs under "Power" it states...
Battery Life: (shots per charge) 310 shots (CIPA), Movies: Approx. 10-15 min of movie recording
Does it have the 4GB limit on individual clips as well? Other Nikon products have 30 minutes or 4GB, whichever comes first.

They should change their name to Zikon to avoid being boycotted by the creative community!!

As a Nikon user, I have decided not to put my expectation too high. So D850 video specs with great video auto-focus and better rolling shutter/low light in the 24 pixel model is what I am expecting, plus all the other good advantage of Mirrorless camera in video like using Evf. The second reason is the Blackmagic pocket 4k. If this camera does not get 10 bit, higher FPS etc, I can use it 90% of the time and the BMPCC 4k with speed booster for those 10% work that will require 10 bit etc.
I would guess that it will have similar capabilities to the D850. Video performance is going to be dictated by the processor, so unless they debut a new processor it probably will not be too different from the D850 in live view mode.
Probably there will be a new second processor handling AF, so performance there should be better than the D850 in live view.

From my own analysis, image resolution for photo and video should never be compared. Yours eyes can analyse a photo for hours if you want, while video is just superposition that moves perpetually. That's why true 2k looks so good in cinema image that are much bigger than any photograph, the first thing as it is moving so fast you cannot scan it (eyes brain) and secondly it is like those smartphone that stack image just move half or quarter pixel and a 12 mp image becomes a 36 etc. Another test is when you look a a freeze frame of a video it looks so much less detailed that when it moves.
Latest image (mock up) from a true sample NR cannot show. The 16.9 screen bodes well for Nikon emphasis on video in this new Camera.
True 4K or true 8K would blow you away in cinemas though. Just because you are used to something and don't know any better does not mean that it can't be improved.

Cell phone sales were sustained by the rapid developing pace of the tech that went into them. Once phones become good enough for most people's needs there is less incentive to replace them and the usage cycle becomes longer. The same sort of thing happened in the PC industry. It used to be that you had to replace hardware every few years to catch up with software demands, but at a certain point software stopped benefiting significantly (from the average users point of view) from hardware advances, so there was less of a need to replace PCs as frequently. That resulted in the much hyped "death" of PCs. But actually, people still used PC's, they just were not replacing them as often, resulting in no growth and some decline in sales. Marketing idiots interpreted that as "people don't want PCs anymore", which was not true at all. Sales growth flattened, but people are still using PCs just as much as before, perhaps even more so. They are just not replacing them every few years like they once did.
The same thing is happening to cell phones now. And we will see the same "death of cell phones" nonsense from business types who only look at sales growth rather than sales themselves.
Basically it has happened to the ILC market as well, hence all the doom and gloom you often see when sales figures come out.

Not FF mirrorless!
I think it comes down to timeframes and lenses. In terms of timeframes, it took what, 10-15 years for digital to "take over" from film? It's hard to estimate because people still shoot film today, and the first digital cameras were completely rubbish, but I think 10-15 years is a reasonable estimation. I'm not sure what the complications of lenses and compatibility was between DSLRs and SLRs during that time, but I'm assuming they had some overlap of compatibility.
In the sense then that MILCs might take 10-15 years to "take over" from DSLRs doesn't seem to be too far fetched. I think we tend to get a bit carried away in these conversations - it's not like Nikon will release two FF MILCs and then never release a DSLR again!
In a sense, the lens mount change is a separate issue, as it just happens to be occurring at the same time as a change to mirrorless, and I think all the logic applies. Even if they started a second line of DSLRs with a different lens mount, all the conversations about adapters and compatibility and flange distance would still be relevant. Needless to say, the quality of adapter for this camera will play a huge part in how well it does commercially.
It will be faster than that. Even for stills MILCs have some pretty significant advantages over DSLRs. DMF comes to mind for example. Precise tracking is another. Or any sort of critical manual focusing if you want to use the viewfinder. The main argument for DSLRs has basically been that you get a more responsive viewfinder, which in some cases you need but mostly you don't. Refresh rates on the latest MILC viewfinders is very fast, so the only real advantage of the DSLR is not really there any more. When you reach the point where DSLRs have no advantages, why would anyone in their right mind buy one?
I think that 5 years from now, no new DSLRs will be coming to the market at all. Everything will be MILCs.

They are doing well partly due to a good product but partly due to zero competition.
No full frame mirrorless Panasonic, no Olympus, no Fuji, no Canon, no Nikon.
That is about to change.
Canon and Nikon don't make FF cameras?
19 hours ago, webrunner5 said:If you ever hold the top end Canon, Nikon bodies, like the1DX, the D5 you Would like them, heck love them. They fit in your hand like a glove, and don't seem to weigh anything like they look like they would, and are balanced it seems no matter the lens on them. They are magic. I regretted selling every one I ever owned LoL. You just can't wait to get out and shoot with one.
Not mine they don't. They are far too big and feel like I am going to drop them at any moment, which is why I would never buy them. For me probably the best camera I have held in terms or ergonomics is the NX1, that is the perfect size and feels like an extension of my arm. All of the pro/prosumer Canon and Nikon cameras appear to have been designed for people with much larger hands.

Storage is cheap. Even if you take thousands of shots, high res sensors are not going to be a problem. If a pro can't afford a 256 GB or 512 GB card then frankly they are not a pro, even if they are selling some pictures.

It is unreasonable to expect something "new" every year. The 8 is great, it is hard to see how it can be improved much, so it should be no surprise that the 9 is similar. They should make it look different why? Just so it looks different? Sorry, that is not "innovation" in spite of what Apple would like us all to believe.
What they should be doing in the annual update cycle is incrementally improving what is inside the phone and what it is made of. If it is necessary to change the form for some reason, or if it makes sense from an ergonomic reason then great, but changing it just so it looks "different" is stupid.
Take the RX100 for example, it looks pretty much the same each iteration (in many cases exactly the same). But what is inside gets better each year. That is what I want in a product I use. It it looks good and is ergonomically functional, then keep what works and improve the internals.

Here's a link to an article about Grant Petty.
I have much respect for the way he and his company does not over charge, even though they could charge more if they wanted too. In particular, the updates to Black Magic's Resolve Studio have been free of charge over the years and now they are basically throwing it in with the Black Magic Pocket Cinema Camera 4k. Yes, I would pay $1295 for the Pocket Cinema Camera 4k without Resolve Studio..
If it takes a few days, weeks, or months past the end of September to ship the Pocket Cinema Camera 4k, I will still be extremely happy with Black Magic, once I have my Pocket Cinema Camera 4k in my hands. IMHO, it will be more than worth the wait.
Lol....the reason they don't "over charge" is because really low price is the only reason people would buy these systems.

Viewing 24p on a 60p device will stutter on pans since it is it is creating a series of duplicates 2 or 3 frames long. Every time you get that 3 frame sequence it will stutter. TV sets have better ways of dealing with that by adjusting frames rates or extrapolating motion, but monitors do not, they run at 60 fps and throw duplicate frames in to make the difference. So if you are watching the footage on a normal consumer viewing device and have not transcoded it into a format suitable for that device it is going to look horrible.
The other issue he will have doing a pan, depending on how fast it is, is lateral distance between objects in individual frames being large enough to see visually, and the only way around that is to shoot at a higher frame rate (which is why 4K60p is so desirable).
-
Why would you be shooting at 24p? That is just asking for trouble. Unless you are shooting clips for insertion into an analog timeline there is no reason, because it will be mismatched against the frame rate of the viewing devices your customers are likely using.
As a general rule of thumb you should shoot for the medium your customer is probably going to be using.

The reason is that Sony are the biggest threat to whatever the fanboy's pet camera is. And it is that way for all of them, which is why it gets so much hate in spite of being largely a superior product compared to the rest. People form a relationship with their equipment and they need to rationalize their choice, which brings up negative emotions when the next guy on has a better option. A telltale sign that is going on when non-quantifiable qualities such as "color science", "cinematic" and "special sauce" start being bandied about as their rationale. As soon as you hear those sorts of things you know they are full of shit
N-log just sounds inappropriate. I guess they were not thinking of the US market when they came up with their terminology and what it sounds like. Although, their insistence on calling it the "Zee" series when the rest of the English speaking world pronounces it as "Zed" might suggest otherwise.
