Here's Gordon Laing-
"I have confirmed that F log will only be on the HDMI output, NOT for in camera recording. A shame since it would be nice to have a flat profile for internal recording even at 4:2:0. Thanks for the tip!"Such a bummer.
Damn. Well perhaps if Fuji receive feedback that this will cost them a lot of sales they may make a change to the firmware. They need to understand that the cost of a 4k recorder is no small addition. And its not like we are getting 10 bit with it either. It gets to the point that people may as well buy a dedicated pro video camera. For such a small change in firmware they could bring a lot of new people to the system.

Dynamic resolution ? Huh ? Did you just make that up ? Lol. Good luck finding "soft" 4K out there
It's what it is by definition. If you increase the bit depth from 8 to 10, you haven't quadrupled the range. You've quadrupled the resolution. Not spacial resoltion, not temporal resolution, but resolution in terms of brightness levels. Call that what you will. Dynamic resolution seems a good term to me. Certainly more accurate than dynamic range.
As for "soft" 4k. Take a look at the image from the Canon XC10.

4k is a resolution animal, so it's overly sharp by it's own nature. These are all things that are easily dialed to taste. As far as dynamic range, in my experience, it has the same dynamic range as any of the 8bit 4-2-0 capture codecs, which is practically all the DSLR/DSLM cameras.
I respectfuly disagree. Resolution and sharpness are not the same thing. As for dynamic range, the codec defines the dynamic resolution (how many steps) but it has nothing to do with the dynamic range. An image with a 4 stop range and an image with a 15 stop range could both be recorded in the same 8 bit codec. Having said that, Its great that people are using the NX1 and finding it to their needs. It just isn't the be all and end all, otherwise people wouldn't still be looking at new cameras.

I have to agree with this, although the Samsung NX1 is kaput in the manufactures support, it's still a pretty amazing camera, and yes, it was way ahead of it's time. The biggest problem for the NX1 was it's acceptance by enough end users, which is why Samsung dumped it. Since the NX1, many cameras have tried to emulate it, the A6300 is a good example. True, the NX1 is far from perfect, nothing is perfect, but the camera will produce one helluva 4k image, that is undeniable!
It was always over sharp though, didn't have much dynamic range, and the rolling shutter sucked. They are the reasons I gave it a pass.

Seriously? 10 Minutes of video recording in 4K? 15 in HD? WATH FUCK??
動画記録は最大3,840×2,160/29.97P。4K記録は連続最大約10分まで、フルHDは同約15分まで、HDは同約29分まで。It basically makes the battery grip essential for video shooting, so we should just perceive it as one item and add to the price accordingly.

Unless it switches to a slower mode when pressing record.
Who knows, the videos aren't telling for now.
Good point. Im sure that will be perceptible to someone shooting video through the viewfinder so it should be fairly simple to test.
-
If the refresh rate for the viewfinder is 100 fps, that to me suggests that the readout speed is 10ms. My reasoning for this is that presumably the refresh rate is maintained in video recording and I cant think of any simple way that two readouts could occur at the same time, beyond interlaced (comb filtering? I dont think so). Much simpler to increase the readout speed. So I think rolling shutter will be fairly reasonable for 4k.
I too have seen a video which was an interview with a fuji employee that said that F-Log would only be via HDMI out . Hopefully this was a confusion, as this would be disapointing for me.
Unless its 10 bit out then it would seem like a massive ball ache to rig up an external recoder just for a flat picture style. Though I can sort of understand why they might to this. So non video pro's will never be able to complain about the "dull colour" for example. If this is the case then I would be more interested in what the inbuilt picture styles can do. Maybe they can be tweaked a little to get more highlight latitude.

Thank you for responding. I'm genuinely interested in the reason for why that is because the difference seemed huge (almost double in size) between the Panasonic f1.4 and the Olympus F2! I know you can change the shape of the bokeh by placing a dark piece of paper with it cut in the shape you want in front of the lens, but I didn't know the front element size determines the size of the bokeh ball... interesting.
Yes, this is very interesting. I didn't believe those samples at first. I thought there must have been something changed between those shots at f2. I thought it was defined by the aperture opening. So if this is true this would explain why full frame often seems to have more blur for the equivalent depth of feild. Because it's a longer focal length the front element is larger so the bokeh balls and also bokeh in general will be more spread out so to speak. Which makes me think, this panasonic 12mm F1.4 could perhaps be thought of, in essence, as a full frame 24mm 2.8 with built in speed booster? Except designed from the ground up of course.

The resolution of QHD is 8,294,400 (3840*2160)
In the case of a raw frame on a native 4k sensor this is precisely how many photosites there are and precisely how many samples there are.
Lets presume you mean 12 bit raw.
So 8294400*12 = 99,532,800 bits per frame
8 bits in a byte so 99,532,800 bits =12,441,600 bytes
1 kilobyte = 1024 bytes
1 megabyte = 1024 kilobytes which = 1,048,576 bytes
Therfeore a QHD 12 bit raw frame takes 11.865234375 MB per frame.
(99,532,800/1,048,576)
If the frame rate is 60 fps the bitrate is 711.9140625 MB per second
If the frame rate is 30 fps the bitrate is 355.95703125 MB per second.
If the frame rate is 24 fps the bitrate is 284.765625 MB per second.
So for 24 and 30 fps the roughly 500 MB per second of the drive is good enough even as recording media.
Its worth noting that even if you are editing 60fps, you will never be literally playing directly off the SSD. The data will first be copied to ram. Once its in ram the ram will have no problem giving the data in real time.

The hybrids are primarily for consumers who want a single camera that can do both jobs very well, and can switch from stills to video mode and back again at the press of a button. They are not really intended for professionals, even though marketing materials might portray them that way. The marketing is not aimed at professionals since they (we hope) know better, but is intended more for advanced amateurs who want to appear "professional". That is why you see Blackmagic cameras all decked out with giant rigs and professional lenses in their marketing materials for example. It is aimed at the wannabe amateurs and "I can barely make it" pros for the most part.
In order to be considered an adequate hybrid, a camera has to excel both in stills and in video, not just one while doing a shitty job in the other.
Does that statment make you feel good about yourself, being above the wannabe amatures and "I can barely make it" pros?
-
No comparison images or videos? I always knew the canon was better because of the image it put out not its specs. The only thing that sours me to it is the lack of super wide angle option. If you need another camera to do that then theres no reason to use that camera to do what the XC10 does as well.

Maybe you should google around and educate yourself? But here's a thought, is every video that has background music a "music video"? Well then?
Actually yes. Any peice of music that at accompanied by a silent (or mostly silent) video is in fact a music video. Whether you think it is a GOOD music video is another question entirely.

well, PEN F looking great...
This video is great because of what it proves.
The moral of this video: Image stabilisation IS NOT A FUCKING STEADYCAM! Stop trying to use it as one. Did any manufacturer ever promote IS by saying how good it is to walk round with? I will be suprised if they have. Its designed to compensate for involuntary hand shake when you are trying to hold the camera still, thats it.
The added distortion an jittering looks worse than if you just walked around slowly with the camera on monopod.
By the looks of it the GX80 will be excellent for getting 4k static shots with a prime lens without a tripod. That is great and all that it needs to be.

I spoke about Live Cropping before, and how this is a great way of doing away with almost every kind of dolly shot (Depending upon whether it is 4k, or 5k, or 6k, and whether the final delivery is in HD or 720p). If the GH5 gets 5k, this could improve even further.
Also, a lot of his shots are handheld (with Dual Stabilization of the lens and camera), and the Live Cropping still looks stellar.
The tracking shots looks really smooth, but with the zoom shots everything was shaking/jerking. I would have said it's posible that the camera was physically skaking but it happens in all the examples. Maybe stabilisation is activated and the zooming is confusing it, or maybe it just doesn't work that well. It doesn't look good though.

5D3 RAW can shoot 1080p 60fps continuously now?
3 hours ago, kgv5 said:5d3 raw with the fast CF card (i use sandisk extreme pro 160MB/s) can shoot continously 50 fps with 2.35:1 aspect ratio. 50 fps with 16:9 gives about 10 seconds, 48fps - 14 sec, 60 fps just 5 second bursts with 16:9 and 13 sec with 2,35:1. Recently i tested 2:1 aspect (looks cool) and 50fps - 18 sec, 48fps - 32 sec, very usable IMO. Everything with sound and global draw ON (all on screen stuff ON), with sound off and GD OFF recording times can be a little bit longer.
I shot this sime time ago, 50fps 5d3 raw, testing new 70-200 f2.8 lens so often lack of focus unfortunatelly.
So, no then. lol. Thanks, that is useful information.

The GH3 has a 2.3 crop. Maybe you're thinking of the GX8, which is more severe.
Unless the technical specification given for the gh4 is incorrect. And if the gh4 uses a native qhd crop then it mathematically must be 2.5 crop. The 2.3 was a mistake that was parroted.

Arguably "new camera award" and "most promising camera award" mean similar or at least overlapping meanings, so I'm not too picky over this.
Oh Right. Thanks for letting me know.

One thing I noticed about the Brighton beach tests on the vimeo page is that the crop for 4k seems relatively slight. I make it about a 1.1 crop. Which works out at 2.2 crop in full frame terms. Beats the 2.5 of the GH4.
-
Yeah, the autofocus caused lens breathing, and I think the auto image correction can make things look wonky with movement at wide angle as well. Add a bit of rolling shutter and shakines that not even 5-axis can tame and youve got the perfect recipy for vomitovision.

Looks pretty rubbish once he pans around, that just me, or what's going on there..?
Look how shaky the unstabilised footage is. I give the stabilisation a gold medal for giving something even close to acceptable. Imagine what it would be like if you actually had smooth camerawork to begin with. That being said. The overal look of the footage in that shot doesn't blow me away.

Why are we even analysing the profits of camera companies? We aren't camera maufaturers checking in on the competition. I mean, I use cameras, but I also use pensils, and i've never one cared to find out what profits the pencil making company makes. I guess if things are so bad the company is going to shut up shop like samsung then it is relevant. But that wont happen with canon. The compacts dying thing is old old news, how long have camera phones been out, jesus. My first camera was a nokia 7250.

Calm down buddy. Its the internet...
If you can't handle criticism, I suggest you keep quiet and never interact with anyone online. In fact, you were pretty critical with a smile, "I playfully and humoursly and accuratly shot down your Idea." I've fired people with a smile... does it make the blow easier for the person getting fired?
If I sounded defensive, I'm sorry... I'm sorry if I didn't sound jovial, add emoticons or add words like "ha ha"
But, in my defense (oh no, I used that word) I did have "lol" in my last post... not enough?
I'm sorry if you thought that I was belittling you... you aren't dumb...
Again, I wasn't clear enough... I said "VR in general, not specifically 360 degree ...is about emmersing yourself in the experience."
But I also said, "Suppose it is a bedroom, and you have a multiple partner fantasy... Suppose you're a girl using VR porn...
Use your imagination..."
May be I should have left a big space to say its a contradicting statement and possibly include the following statement, [Then again, there is a place for 360VR porn such as]
Ok fine, my fault.... but to be honest though.... (No emotion here, totally stoic) I don't agree, that "360 degree vr porn would be useless."
My reason:
From a business point of view... porn isn't just for heterosexual men anymore. Well, there is obviously a whole faction of gay porn.
Not to mention... what... 60% of the population are women... and some of them are lonely and/or horny women that watch porn.
If I was in the business of making porn, VR porn or 360 VR Porn... I would make something that will make the most money, hence make 1 video that is beneficial in terms satisfying everyone's fantasy.
Now for light hearted humor:
Here is something with a smile, I'm humorously and jovially saying "fuck off!"
Wait for it.... Hahahahahahaha!
Not enough? LOL and LMAO... over and out.
Comment failure! Mine was better. Now write annother essay.

I see that it won new camera award from news shooter.
Wow, Is there anything more pretentious someone trying to elevate their own importance by issuing awards. If it does have to win an award, it should be "most promising camera" As we haven't seen it working or seen footage from it.

Its funny you put 'color' in capitals. What about a monocrome bitmap image? You do know that there are different types of resolution than display or image resolution right?
Take this list from wikipedia. I know it cant match your six exlamation marks, but it's at least a start:
What we are arguing here is merely a question of nomenclature. We can call it anything, Its still a discrete concept from dynamic range. If 'dynamic range' is acceptable to denote the maximum range of light intensity recordable, then then number of discrete values with which we can sample this range would clearly be described as a resolution. And if the word dynamic is good for one, why not the other.
