    I agree, it's probably pixel binning to produce the 4K from 12K but i was just quoting the cinematographer of that nice drifting video verbatim... that's what he said. Maybe it's not right, maybe it is... who knows :)

    Pixel binned or line skipped. It‘s just that the Sony data sheet, a bit of technical knowledge and common sense suggest no 12K read out :D

  2. I now read trough the whole review. I think you should go work for Fuji. Why?

    With a faster sensor readout comes better contrast-detect autofocus as well. Maybe this is asking too much on a 50 megapixel medium format sensor, but if they could optimise the speed at which the sensor scans they could bring that benefit to the contrast detect AF system as well

    That's actually what they did. The 50s uses a modified sensor, for faster read out (around 1.5x faster). That's probably why it focuses faster than the X1D and why it's viewfinder has a higher resolution. 

    One thing I can't wrap my head around is the following claim about the H6D 100C

    Quote

    The full width of the sensor is used with top and bottom cropped to give 12K 16:9 video down sampled to 4K in camera

    Doing the math, that would mean reading and processing no less than 81MP with every picture and that, 24 times a second. That's nearly 2 billion pixels processed every second. That would need enormous power and I just don't think any current stills camera processor can handle that amount of pixels. It also doesn't seem right if you look at the specifications of the sensor that Sony released. 

    Anyway, even getting straight 4K off such a sensor is a huge achievement and we can only hope, that it trickles down

    And how do we know a GFX100S is coming?

    I think that was given since Fuji introduced the GFX50s with lenses, which handle 100MP without a problem.

    Are we reading the clickbait rumours sites again?!

    I don't think you need any rumor site. The IMX461 100MP 44x33mm sensor is coming. Phase One already has cameras with it on preorder. Fuji will probably add phase detection focusing to it. Might be a few other tweaks too. Don't know about Hasselblad, but would make sense to go the Fuji route. 

    edit: here is the IMX461 on the Sony page: https://www.sony-semicon.co.jp/products_en/IS/sensor2/application/index.html

    What I am personally looking for, is for one of those medium format camera manufacturers to go into video. The Hasselblad lenses made by Fujinon have been modified to work on the Arri Alexa 65, so we know the glass is there. Neither manufacturer has a video camera business those cameras would hurt, like Sony, Canon or Panasonic have to protect theirs against their smaller cameras. 

    While 10000$/€/£ is a lot, I think quite a few would be very interested. Especially the Fuji, with it's modular approach. If you could directly attach a monitor instead of the EVF for example.

    By the way the H6D-50C with similar sensor to the Fuji GFX 50S does actually do RAW video as well. Just 2K. Would love to see what that's like.

    Yeah, 2K would probably be possible. But I don't think Fuji will go this way. They probably still think, that the 50S is a pure photo camera, the video is just for the specs. Wouldn't have to be 2K Raw, I think adding some of the X-H1 features, like silent control, 200Mbit Codec, Eterna Filmsimulation with 200% and 400% Dynamic Range extension and Flog would be very welcome. 

  4. 4K won't happen on the 50MP medium format cameras.

    But it will happen on the 100MP 44x33mm cameras (x2D, GFX100S) coming next year. The sensor can do 4K 30p 12bit, but I wouldn't expect to see 12bit, RAW or even 10bit in those cameras. Too much heat. Still, would be nice. Imagine a medium format 4K camera with ProRes Raw :D 

    the sensor could probably also handle 8K, but I wouldn't expect that either

    Xtrans - IMO - is keeping Fuji a little behind the curve.

    For videos this is very likely. For photos it's another discussion. I think X-Trans does offer some benefits, but also has drawbacks. Depending on what you shoot you might prefer it or Bayer

    To be honest, I would have thought they would put Bayer into the X-H1 due to it being more videocentric

  6. 4K Burst with 1 second pre recording, 4K Multi Focus, 4K Timelapse. 

    I think the 4K of this camera isn‘t as much about video as it is for stills.

     

    What I do find interesting is, that the camera can do 30 minutes of video recording. Seems like the X-Trans sensor and X processor really generate a lot of heat

     The XA bodies haven't seen any significant FW updates compared to the XPro and XT lines, I doubt this gets anything beyond bug fixes

    The X-T100 is claimed to have much better focussing than than the X-A5. And those algorithms as well as 30 minute video recording are coming to the X-A5 in a firmwareupdate soon :D

  7. The 5D classic already has some followers, same goes for CCD sensors. 

    For Nikon cameras those not using Sony designed sensors might be considered something special, but one of the most interesting camera with Nikon F mount, was the Fuji S2 pro (and S5 pro), incredible dynamic range for that time, very nice highlight roll off due to the dual pixel sizes and colors, especially skin tones, that many people still consider to be some of the best ever.

    Didn‘t have many buyers back when it was new, but those who ever used it fell in love with it

    Leicas will always be classics.

     

    For video? No idea, that seems to be a much harder task

    Its impressive stuff though. The Kipon version with the focal reducer is the one I'm hanging on for.

    Yeah, it's very interesting, too bad that the Baveyes Kipon speedbooster, is optically by far the worst speedbooster. Would be nice to see Fringer collaborate with metabones.

    I don't think its out until next month.

     The low light limit for AF being extended and being able to use it up to f11 should be simple pass/fail though.

    The other two changes are subjective and will need someone who tracks oncoming birds in flight at varying focal lengths to test !

    The AF improvements coming to the X-T2 are already in the X-H1, so it could be tested. And it's not like f/11 fails to focus, it's that it will now work with phase detection autofocus, which ist faster.

    That's not how dual processors work on mobile devices, they cannot do parallel tasks like computers with dual socket CPU. One processor is responsible for specific set of tasks. So it's not like 30p for each processor and you get 60p.

    Yes, but those Fuji Processors are said to handle close to 500MP/s. I guess it would take a second processor to do camera operations, autofocus, liveview and so on for a single processor to do 4k60p. But then again, probably the sensor was limiting.

    Anyway, here is what Fuji had on their press presentation slides about the new processor when they released the X-Pro2

    I don't know who to believe here, but according to @Emanuel's site recommendation: https://photographylife.com/fujifilm-x-h1-vs-x-t2

    The X-H1 does have dual processor... now how much of either processors is working on IBIS calculations, who knows.... but may be if we turn off IBIS, we can also engage 4K/60p  & 10 bit... RAW through HDMI pretty please!

    They got that wrong. Fuji was thinking about dual X-Processor and those ideas go back to 2016 and the introduction of the X-Pro2. But they opted to not go that route. Neither the GFX medium format camera nor the X-H1 have dual processors. It seems, the processor puts out a lot of heat. That's why the smaller cameras have problems, the X-A5 can't use the processor but has to use a different one. 

    What the X-H1 has and I guess that's where the site got it's wrong idea from, are separate dual processors for the image stabilisation system, but those are independent of the main processor and don't support it with image processing

    With all these upgrades to the X-T2 - what 1.5 years after its announcement?

    I don't see why they can't do the same with the X-H1 - I mean - 4K/60p internal, 4K/120p external, 10bit 4:2:2 and RAW out..... 

    I think most of those are hardware limitations. 

    A single X-Processor can handle 4K at 30fps, dual processor would have been able to handle 4K with 60fps, but Fuji didn't put those into the camera. I think the sensor might have handled 60fps, but not with downsampling. Just line skipped. 

    The most we might hope for would be 4K 30p 10 bit, but even that might just be too much heat. But let's hope, wait and see. But I think we will have to wait for new hardware to see 4K 60p or faster

    31 minutes ago, mkabi said:

    BTW, I wonder if the X-T2 will show the same aliasing/moire issues in Slow motion.

    I think it will. I suspect, that the Slow motion is line skipped and not downsampled and that results in moire and lower resolution.

    Sorry mate, my bad, very likely. I've just arrived to their digital range now : ) Sony and mainly Panasonic have been the scope of my standard in the video realm so far. Fuji to me was Fujifilm, literally :-)

    It‘s no surprise, that people in a videocentric forum don‘t really know a lot about the digital Fuji cameras. The first generations (X-Pro1) video was unusable. Second gen (X-T1) was bad.

    That‘s why it was a big surprise, when Fuji had very nice quality video with the X-T2 and improved upon it, especially on the Handling with the X-H1.

     

    Their firmware policy, often called Kaizen philosophy, developed more out of need. Their first cameras, X100 and X-Pro1 were missing quite some feature people were used to and had some bugs. So Fuji improved, and improved and kept improving. Just zake a look at the list of improvements for those cameras

    http://www.fujifilm.com/support/digital_cameras/software/firmware/x/xpro1/history.html

     

    With their new cameras they kept that philosophy and add most features from new models which. Very nice idea, but it needs a lot of ressources. And if you look at the comments of fujirumors, people are actually complaining, because they want more and more

    Seems Fuji follows Panasonic on firmware updates of significant importance. Nice for all of us, their customers :-)

    I think Fuji was one of the first to roll out significant firmwareupdates. Only it was with stills until now, since their cameras weren't really made for video. All Fuji cameras have gotten many firmwareupdates, it's something one should think of when buying it.

    The X-T2 was introduced at the beginning of July 2016. And it gets some very nice features like internal Log recording or slowmotion for free now. 

    It won't match the X-H1, will still be missing features like 1/48s shutter speed, 200Mbit codec, Eterna film simulation, DR200% and Dr400% and other features and of course it won't get features similar to a GH5s, but I think X-T2 buyers never expected those to happen. 

    Overall it's very nice to see those things added, for those owning both X-H1 and X-T2 this helps a lot.

    BMD is a small player, they're probably not even on Panasonic's radar. If anyone is interested in RAW HDMI out, they should keep requesting it in the forums and on YT channels that review Panasonic products.

    They should be on everyonce radar, they are doing a great job.

    I am not saying, that the GH5s looses all it's advantages. It still has the most capabilities for a combined machine, doing both stills and video. 
    Especially the combination of GH5 and GH5s is interesting. Similar color science and easy to match. And of course, the GH5s has to be viewed as a whole. It probably does stills better than the BMPCC and has a lot of features for stills photographers, that the BM won't offer.

    But if you compare the GH5s and the BMPCC 4K purely for their video specs, the BM looks to be a bargain.

    The Fuji sensor is Fuji's X own design, the Hasselblad uses a Sony sensor. Big difference.

    all 50MP CMOS sensors are based on the same design. Hasselblad, in both the X1D as well as the 50c backs, Phase One and Pentax use it as it was designed, while Fuji had Sony make some modifications. But the sensor delivers 14 stops of dynamic range per pixel, the adcs are 14bit with all of them. More color depth wouldn't make any sense, since it would only slow the cameras down even further

  17. 13 hours ago, webrunner5 said:

    Plus the reason the Fuji is Only 14 bit is that they used the processor out of a X-T2

    I haven‘t followed the whole dicussion, but this part is not right. The Fuji has 14bit RAWs, because the sensor is only 14bit. At least that‘s what a Fuji engineer said. All those 50MP cams use the 14bit sensor, everything above is just air.

     

    Overall a higher bit rate only makes sense, when the sensor supports it. Pentax had 22bit with their K10d. No improvement, because the data just wasmn‘t there

    the new CMOS 100MP medium format sensor seems to go beyond 14bit dynamic range, so the 16bit adcs make sense

  18. All of those shots with the Samyang 14mm? Since it has no contacts thus doesn't communicate focus distance, the camera only compensates for 3 axes and those aren't even the most relevant for walking. Really interesting to see, that it performs nicely even though.

    I'm debating whether to get the grip. Does it run off 3 batteries in total with the grip attached? So one is in the camera, and two in the grip. I believe battery life to be quite a bit above average (when not in boost mode), for a mirrorless camera. Although for stills, vs a Nikon D5, obviously it isn't going to run as long on a single battery. 900+ shots on the grip though, I believe?

    I would have advised, to get the grip as a bundle, since Fuji gives you another 2 batteries with it for free. So the kit comes with a total of 3 batteries. If you buy it separately, you don't get extra batteries. If you don't own the grip yet get it if the recording time is limiting or you want the headphone jack. If not, I'd keep the camera small. But that's just a personal preference. 

    Oh, and the discussion about ETTR is really funny :grin:

    I'm more concerned with the rolling shutter on XH1. it seemed to me worst than XT2 (borderling A6xxx). But maybe i'm wrong. Perhaps @frontfocus or someone could compare/measure it and report back to us on that.

    I don‘t have a way to meassure it, but I can directly compare it to the X-T2. I‘ll probably do it tomorrow and report back

    I have seen someone saying there's only 40mbit/s for 120fps.

    please can someone who already own x-h1 at hand confirm this? I wonder if this is a case for in-camera slowed down footage ( and then its kinda make a sense: 40 * (120/24) = 200)

    it records in 200Mbit/s. Depending on what recording frame rate as well as playbackframerate you choose, it reports back differently.

    120fps shooting to 24fps (5 times slowmo) shows 40mbit/s (200/5)

    if you record 120fps to 60fps it will show 100mbit/s and so on
