    I had a feeling the case was going to be dismissed. Here's why - Nikon was approaching the case with evidence that Red should never have been granted the patent in the first place. None of the other companies Red sued took this approach. My guess is that Red realized there was a good chance they could lose the case. Rather than risk having their patent taken away, they walked away instead.

    Both sides have now filed a joint motion to dismiss the case so it’s all over.
    Whether this means Nikon are paying a license fee or it’s a “win”’ against the patent itself that will benefit all manufacturers is uncertain but it looks like that new Z8 might be even more compelling now.
    Perhaps the timing of the settlement and its launch may be more than coincidental.

    Sharathc47 reacted to Attila Bakos in Fuji X-H2S   
    I'm fed up with Atomos, I wasted a huge amount of time doing tests for them for the stuttering issue in ProRes RAW. They didn't even try to replicate it. I reported the problem at the 8th of February, since then I provided tons of test material. And where are we now? They still think it's my unit, or my SSD or my HDMI cable even when I told them I tested with multiple units, multiple cables and SSDs. Unbelievable.
    In the meantime some other guy asked BlackMagic about the same issue (so apparently this is related the the X-H2s), and they sent it to their engineering team right away, they reproduced it and notified Fujifilm about it. HUGE difference between the two supports. Seriously, even Fuji is better than Atomos, because they don't reply at all, so you won't waste your time with them 🙂

    I could only download one example which did not have it but I don't want to base my opinion on one example only. Does anyone have downloadable 6.2k BRAW from the X-H2s?
    However people already confirmed to me that BRAW also has the stuttering issue so it's definitely a Fuji problem.
    In general I would prefer ProRes RAW since it's true raw in a sense that it's needs the same processing as a common raw file after it's decompressed. BRAW seems to be more processed with slightly less color detail, but I believe you'll only see it when pixel peeping. The obvious difference is that BRAW works in Resolve, which is a big plus given how large these files are, it can be a pain to convert ProRes RAW.
    But anyway both of them are unusable at the moment, I have a feeling that we only have raw for marketing reasons in this body. With the current issues and less DR it's garbage.

    I analyzed the raw data in the DNG converted from ProRes RAW and now I know exactly how it's messed up.
    I adjusted my tool and I think I have a working fix now. It fixes the raw data itself, so the result will be perfect in every software that reads DNG.
    Before (see the broken line in the middle):

    After:

     
    I'm still testing my tool, it can read 12/16bit DNG, uncompressed, or lossless compressed, the lossy formats are not supported. It uses multiple threads, on my recent i7 laptop it converts with 25-35fps.
    It's a pain to convert twice but at least I got it working, and learned a bit of C++ on the way.
    If only I could fix the framerate issue as well, but no chance for that.

    Remember we discussed earlier that X-H2s 6.2K ProRes RAW has a hot pixel at the exact same location for everyone?
    I spent days to create an executable in C++ that removes that hot pixel from the DNG raw file created from ProRes RAW.
    I was just about to post it here but then I noticed that this is not a hot pixel issue at all! All pixels in the same row right from the hot pixel are shifted towards the right.
    See here:

    It starts with the hot pixel, and it goes all the way to the right edge.
    Or here (this is the right edge of an image, you don't see the hot pixel here, it's somewhere in the middle):

     
    Atomos says it's Fuji's fault, and as usual, Fuji couldn't care less.
    Atomos is also silent about the framerate bug I discovered. A new firmware was released just now and it's not fixed, it's not even listed in the known bugs.
    Stuff like this makes me really disillusioned.

    I don't think the issue is Phase Detect because V-Log on the S5II (while sharper than before) has not the insane sharpening and chroma noise reduction that the standard profiles have.
    Moreover, nor my A7III and IV smooth details like this at low ISO and yet they use Phase detect.
    There are just bad processing going on internaly on the standard profiles with the S5II.

    A small update on the X-H2s + Ninja raw recording. We tried another body and another recorder as well, and this is a general issue, not related to my unit. When you put the body to 6.2K raw mode sometimes you will get like 12 fps. It's easy to reproduce it when you switch between 23.98 and 24fps 10-20 times, at some point you will enter this low fps mode, and sometimes it stays in this mode even if you hit record. Really annoying.
    I also checked this another X-H2s body for that specific "bad pixel", and it's there, only in 6.2K raw mode, so this is a general issue as well. However, it was not visible when we used the Ninja V, it's related to the Ninja V Plus.
    I'm discussing these with Atomos already, will keep you posted. However, Fuji doesn't reply to any of my emails, so if it's their fault, I'm not sure what I can do.

    Sharathc47 reacted to newfoundmass in Dear Panasonic: let's get some power zooms!   
    I did a shoot over the weekend that required a lot of zooming in and out. It really made me long for the camcorder days and made me ask myself: why doesn't Panasonic release some power zoom lenses? 
    I know they have a couple of lower end ones for M43 that aren't constant and are very slow, but why no higher end ones? I'd buy a 24-105 f4 power zoom lens for full frame (and a 12-100 f4 for M43) in a heartbeat. I can't be the only one that would either. It'd be the perfect lens for event shooters. 
    Right now Sony is really the only one offering power zooms. I think it's time for Panny boy to get in the game.

    Hi All:
    I decided to bite the bullet and upgrade to firmware version 3.0.  I am delighted to report that communications with the RS2 did not change as a result of this firmware.
    As for for video auto focus, I took 8 clips at 60 FPS of ring tail doves against trees denuded of leaves.  Of these 8 clips, only 1 was out of focus.  Balance were sharp.
    I also took 4 clips at 120 FPS.  Three of them were of ring tail doves against the same denuded trees.  All three clips were in-focus.  The fourth clip was of grackle in the same de-nuded trees.  Because there was more contrast between the bird and trees I expected that this clip would remain in focus.  It did not.  That was a disappointment.
    More testing is required.  But my first impression was the video autofocus for version 3.0 is an improvement over 2.1.  However, FujiFilm still needs to continue to make improvements.  I look forward to the next update.
    Don

    For me, the clincher was that phase AF works with my old EF lenses with the MC21

    Lol, I saw that video and I usually quite like Sam Holland but the title is a little bit clickbaity. For anyone that's interested he's talking about focus transition which has been around since the GH5. Maybe the reason that nobody's talking about it is because everyone has been aware of its existence since 2017! I guess it was missing from the S5 though, which is what he seems to be most familiar with.

    To anyone who is interested in recording ProRes RAW with the X-H2s, I just got confirmation from Fuji that they convert X-Trans to Bayer in the camera, as I suspected. Because the two patterns are different, you have to calculate what's not there. So let's say at a given pixel X-Trans stores red but for Bayer we need blue. I asked Fuji if they interpolate this blue using the surrounding blue values in the X-Trans pattern or they just copy the value of a blue neighboring pixel. The latter is faster but more prone to artifacts. Unfortunately I received an one-liner that this is proprietary info.
    I'll know more when I test this out myself, I'll receive a Ninja V+ in the following days.

    I am all up for that. It would be very promising for BM to enter L-mount alliance and license BRAW to everyone there. They need a mirrorless mount anyway and L-mount seems to me like their best option. Lots of glass and ability to adapt EF lenses the like so much.

    Well that's it, deal done; S5 and S1H being 'traded' for a pair of S5ii's. MPB collecting tomorrow, new boys on pre-order...
    I would have preferred a pair of S5iix's, purely for their look (don't need their spec, - anything over 200mbs not required) but as they are not available until end of May/early June and my next season starts end of March...
    I'm going to miss my S1H for sure, but this is going to be a better pairing for my video needs being:
    A. Identical bodies.
    B. Both having a built in fan rather than just the S1H (though the S5 never overheated a single time).
    C. The AF of course for which I have a need, especially with regard to shooting log because shooting that only made the AF worse with previous Lumix cameras.
    D. No 30 minute time limit as with the S5 which was a pain.
    Body A will be paired with the Sigma 16-28mm f2.8 and Body B with the Sigma 28-70mm f2.8 and that's happy days for the forseeable future. My only wish would have been the tilt screen of the S1H (or even the S1/S1R) but that is the ONLY compromise with this camera for me. For my video needs anyway...
    For stills, sticking with my trusty S1R's for the time being. I had already sold off my f2 Sigma primes. Loved them, but going forward, really wanted something a bit faster for the low light stuff so bought 3x f1.4's, the; 20, 35 and 85.
    I'm in no rush to replace them and had considered a complete S5ii lineup, but I reckon either Panasonic or Leica will come out with something maybe for next year that will update the S1R significantly enough for me to replace them.
    The ideal now would be an S5iiR model, but an S2R or something Leica flavoured would do it.
    On the other hand, I might just trade the pair of them for a third S5ii body as a 3 body set up rather than a 4 works better...except during wedding ceremonies and speeches unless I switch to a 3x zoom set up for those times.
    We'll see but glad I stuck with Lumix after considering; OM-1, XH2/S and even a wholesale switch to Sony.
    Faith restored in Lumix/L Mount. Hadn't really lost it as such but I had a concern that they might just blow it and not go phase detect but realistically, that would have been suicide for them.

    I must say... I do really love this camera. Disclaimer being Panasonic is loaning me the camera and lenses and paid for an entire Tokyo trip. 
    I'm trying to be as objective as possible, but the AF performance has been surprisingly good. I love the IBIS and the color science is great. It doesn't feel as premium as my OM-1 or even an R5... but this isn't in that price bracket. The fact that this camera is this good, all while being under $2k is actually a big deal. 
    Makes me excited for an S2H... or other flagships. I still love micro 4/3 and think the 10-25 panny/leica is one of the best lenses ever. I can't wait for a GH version of this camera with phase detect!
