  1. About the AF, an opportunity that DJI could have (and probably will not do) - take that LIDAR Af system and the 1000 nit touch display from the Ronin 4D and embed it in a package with an AF motor.

    "GH6 offers a new “dynamic range boost” mode, where two ISO values (ISO 800 and 2000) are combined into a single exposure".

     

    You know, you have to use this method when your sensor is not isoless. Sony sensors are isoless from iso 500, which means iso 500 is so clean that for any higher iso you don't get cleaner image using "analog" amplification, so you stop there and lift the shadows logarithmically to save the highlights. So your iso 6400 shot is not really iso 6400, its iso 500 or 800, plus lifted shadows.

    Arri had to use that tech because back then cmos sensors readout were really noisy, so analog amplification at high iso could help a lot. 

    I guess that ISO invariance apply to RAW files, not compressed video (but I could be wrong).

  3. And I was caught by surprise that the GH6 is the first Panasonic camera that you could punch-in to focus (without recording it)? I was sure that the GH5 already have that - is the most loved video resource that my X-S10 have and a thing that I always missed when I used my Panasonics and Olympus.

    Some tidbits that i noted in quick readings (don't have time now for full reviews):

    - As said in the response above, looks like that Panasonic is REALLY not using a Sony sensor this time - that explains the odd 25mp resolution;

    - AF-ON button, finally m4/3 cameras have a proper one. Hope that it goes down the lines (if there will be any);

    - The camera have the same weather sealing resistance as the GH5 - the fan part is sealed from the electronics inside;

    - The promised firmware update to record in external SSD drives using the USB port is a huge bonus;

    Looks like a very solid camera - and maybe with some tweaks, the AF could work for a lot of cases, for sure less than the competition.

    Forget the audio part - dedicated button to bring the audio settings, and native 4-track audio?

    @IronFilm will be delighted. 🙂

    Panasonic's excuse for not implementing PDAF seemed quite poor and hard to believe.

    In fact, it is a new excuse - the prior one was that the PDAF pixels degraded image quality (was at that time that it was an issue in Sony and Fuji cameras - the PDAF strips appearing in some light angles).

    Still don't get it, but now it could have another reason - DPReview said

    "The GH6's sensor, which we're told is 'not made by the company everyone always assumes we use,' features a dual output gain design. This is not to be confused with the switchable dual gain sensors we've seen in an increasing majority of modern cameras, but instead is closer to the design used in Arri and some Canon cinema cameras. The sensor has two, parallel output paths and at high ISO settings, the output from both paths is combined to give both highlight and shadow detail."

    It is a hint that it is not a Sony one, and maybe the new manufacturer don't have expertise in PDAF sensors. WHo makes the Arri's sensors?

    Decision made: S1H + S5 (plus some lenses) outbound, pair of OM-1's inbound.

    Sticking with Panasonic S1R/L Mount for at least the time being until I can test the stills capability of the OM-1's.

    Of course they are not going to match, never mind beat, the 47mp FF S1R, but how close can they get and is that 'close', good enough...

    For my video needs however, I just need that 'well above average' and reliable AF.

    The fact that it will come in a lighter and more compact package, is a bonus.

    I've had 2 absolutely shitty years financially and perhaps more importantly, creatively.

    The work I have booked in this year is an absolute opportunity to make a massive dent in the latter and I really don;t wish to be going into it with compromise.

    Not 100% decided on lenses yet, but pretty sure it will be the Panasonic f1.7 pairing of the 10-25 and 25-50, plus the Olympus 17mm f1.8 for gimbal work.

    Just need to find some used versions of all the glass in good nick.

    EXTREMELY sad to see the S1H and S5 go.

    The S5 less so because despite it's excellent photo and video output (plus nice size and weight), I wasn't 100% happy with various other aspects. Great bit of kit, but not quite good enough for my needs.

    The S1H has been the best camera I have ever owned. For video at least. Could have been a bit smaller and lighter and the only real 'deal-breaking' issue for me has been the less than decent AF and the wrestling & fudging I have had to do to get around it.

    Obviously, the new boys have not arrived yet and won't until March, but they tick all the boxes for my needs and the only criticism I could level at this time is that they are maybe a little over-priced and something more like 1950 euros might have been more appropriate.

    I believe it's the right decision for me and my needs.

    The S1R is going to be a tougher one to replace, NOT THAT I AM LOOKING TO!

    By divorcing my video needs from my stills needs totally going forward, it does give me a few other options and my preferred one would be to keep it all 'in house' with 3 matching bodies and cross platform lenses.

    Absolutely zero rush though as anything that isn't the S1R would need to be a bloody good option!

    Good luck - but be sure to try the OM-1 first.

    Looks like I was the only one underwhelmed by the MTB video - for me, looks like that Olympus still have a huge codec problem, present since the original EM-5, kinda mitigated now but still present: the image starts to degrade when a lot of details are present in the scene.

    In the original E-M5 and in the first firmwares of the E-M5 II, it was easlily detected - point the camera to a tree with the leaves moved by the wind, and you can see the image "blocking". When the bitrates where raised in the firmware (I guess) 2.0 for the E-M5 II, it was still present, in a much lesser extent.

    I guess I saw some hints of it in the MTB OM-1 footage, specially in some slo-mo parts. Hope I'm wrong - liked a lot the O-M1.

    If M43 is in trouble, so is Fuji and FF. I'm not really bothered by companies closing up shop as there are still a bunch of cheap bodies and lenses for a lifetime- that's just reality (I probably have enough right now). You make a really good point about margins and I suspect there will be pressure from investors to make money.

    The Olympus sale was a little more complicated than what many think. Yes, Olympus couldn't make money in M43, but this was primarily debt from scandals and a new factory. The sale of JIP eliminated much of the debt and allowed them to restructure. I think there are significant opportunities for them. In video, they could do damage as they don't have a cinema line to protect unlike Sony, Panasonic, and Canon. Also, it's a fact that many people just won't use a phone for photography or video (me included).

    The reason I think there might be a new PEN-F is that OMDS is showing they're interested in nostalgia of former great cameras and the PEN-F is one of them. I'm not sure it matters that people want or don't want to buy it and they can price it in a way that makes sense to their profits... someone's going to buy it.

    In terms of Panasonic, I truly believe they don't know what they're doing anymore. They're doing too much and not enough with all of their imaging business. I'm worried for them, much more than OMDS.

    My dream (besides a really good Pen-F II): one digital Olympus XA. 🙂 I have the original and it is amazing.

    I don't understand it to be honest. The LX100 and the G7 I have had were really good, damn good CS wise. Even the GH3 was not bad, but man the GH4, GH5, well not worth a damn I think. They went backward.

    Each one is really each one, hehehehe - I still have the LX100 (will never sell it), but I think that its colors have a very greenish cast (like the GH4, who is in the same generation). My GX85s and GX9 (specially the GX9) have m uch better colors for my tastes.

    Its almost like affordable app controlled motorised sliders with pan/tilt heads that can repeat moves ad nauseam don't exist isn't it ?

    I do think, though, that more emphasis needs putting on having an "AF Toolbox" as opposed to an unrealistic (at this moment at least) ideal of the "Sentient All Seeing Eye AF".

    Focus limiters, range traps, spot focus, hybrid AF-C with manual override etc can all combine into a powerful toolbox that can be used to more ideally match the different circumstances of shooting that people find themselves in.

    Manufacturers have a lot of these types of tools available but bury them in menus and don't really pay much heed to fast switching between them with hardware buttons, something which is essential if you want to provide a cohesive system.

    I also have a focus recorder function in the AFX that lets you record and playback a couple of minutes of real time focus moves sourced from any combination of AF-S, AF-C, manual or focus memories and then play them back so you can perfect the moves that you want for a scene and then replay them for take after take. 

    Stuff like that can also help provide the tools to cover a lot of bases while we await the golden ticket with the bonus of it all being able to work on decades old manual lenses as well as it does with the latest and greatest fast AF lenses.

    We are definitely in an era of making perfect the enemy of the good when it comes to focus control.

    If we turned our definition of AF to mean Assisted Focus rather than Auto Focus, we might see a lot less angst about it.

    Yep. Just moved to Fuji, and I've saw a lot of people saying that for the AF works well in video, you should choose the right C-AF mode from the 5 customs settings that the camera have. Did not dabbled too much into it, but for my current filming environment (a.k.a. 3 year old daughter zipping through the house), with a little tweaking the video AF became MUCH better.

    Thom Hogan says the same for Nikon AF - right out of the box it is not the best, you have to know how it works and tweak it.

    Maybe. My impression is also that a integrated battery grip model is unnecessary at this point. However, my guess is that a PEN-F ii will be on the horizon. I only judge it because OMDS is demonstrating that they are also a company that commemorates the past and so many people have asked for a new PEN-F. The E-P7 didn't cut it in its build quality.

    This is what I doubt - and was one of the reasons that I moved to Fuji.

    Panasonic last lens launches were the 1.7 zooms, and the only camera rumored was the GH6. OM is beaten the drum of "wildlife / ruggedness", and launching PRO lenses. Looks like that they will focus in these niches, and only in higher price / higher margins.

    After the G9 (which, maybe, got a sucessor, but I don't bet on it), Panasonic released the GX9 (VERY underrated camera, it is very good, but is a GX85 slightly upped) and the G95 (GX9 internals in a bigger body, plus some little extras). No proper GX camera (with good EVF, lots of controls), the GM line is vanished.

    Olympus crippled the amazing E-M10 MK II in the MK III, and the MK IV is just a new sensor. The E-P7 was kinda hinted to be the Pen F sucessor. The E-PL and E-PM lines are dead.

    My guesses: Panasonic will launch the GH6, maybe a G10, and wait. Maybe a G100 and a GX10, but if these cameras did not sell, they will kill their MFT line. And all these occasional financial publications talking about they thinking to sell their camera division remembers me a lot the Samsung and Olympus cases.

    OM will probably launch an OM-5. A proper Pen F sucessor would be amazing, but AFAIK, despite all the enthusiasts crying for a sucessor, the original Pen F sold much less than antecipated - because of the high price, and a sucessor proabaly would be in the US$ 1100 range, with a X100V costing $1400 with a lens, or an X-E4 at $849,00.  

    If Panasonic and Olympus could make a turn in the MFT sales, I guess this is the last MFT generation.

    That is with battery and memory, GH6 weighs 823g with those included.

    A far cry from OM-1’s 511g, the exact same weight as it’s original 1972 35mm counterpart! Gotta love that attention to detail..

    Fun fact - last year I come across an OM-1 (the film one) for auction with a 50mm f/1.8, gave a US$ 80,00 bid, and won. Got the camera, was in VERY good condition, and the lens was pristine.

    My E-M10 MK III was sold this week, hence this is the replacement. 🙂

  13. Specs and a HUGE 32 minutes in video leaked, showing the camera in detail. S1H-like hinge and vents confirmed.

    Dynamic range boost function: It is possible to shoot a wide dynamic range image at a maximum of 60 fps by synthesizing an overexposed image and an underexposed image in real time. Achieves a dynamic range of up to 13+ stops approaching the full size. The minimum ISO sensitivity is 800, and when using V-log it is 2000, so an ND filter is essential.

    Image stabilization: Adopts an ultra-high performance gyro sensor and a new algorithm, and has a correction effect equivalent to 7.5 steps. Smooth image stabilization that is ideal for movies.

    Dark place performance: High-sensitivity noise is much suppressed compared to GH5II while increasing the number of pixels. It can be used normally up to ISO3200.

    Built-in microphone evolved from 16bit to 24bit. 4 channels can be recorded when using an XLR adapter.

    Phase-difference AF is not installed, but AF is much better. The AF calculation speed has tripled, the background omission and tracking performance have been greatly improved, and the AF speed has also become considerably faster.

    There are 315 AF points in the full area. Human, face / pupil, animal + human subject recognition can be used in all AF modes. The focus range can be set with the focus limiter.

    This guy has some low-light slow-mo footage. Interesting review, but I hate mouth-open thumbnails- sorry about that! He only has 500 subs.

     

    How in hell a guy with 500 subs get a pre-production camera, and some OM embassadors not?

    (we know the answer)

    I don’t think simply fixing the AF situation alone would be enough.

    It would be a start, but then needs some shouting about as a brand/system.

    My fingers are crossed, but I’m not holding my breath.

    The ‘savior’ of the DFD could be computing power from what I understand…but that’s not something I know too much about.

    GH6 will be an indicator. 

    Specially because, as the GH5 II got some features using the S5 processor, probably the GH6 have the same processor that will be used in the next generation of their L mount cameras.

    It would be a bonus point in my eyes if the GH6 has the same/similar tilt screen as the S1H rather than a vloggers flip out.

    #bestLCDever

    Indeed. Should be standard on all cameras.

    Fuji made a cheaper version of it in the XT100 (which was enough for me), but abandoned it.

    Not for me. I went from M43 to a Sony A7r ii, said screw that, went back to M43 and swore I'd never leave again. Why? Size, cost (especially lenses), value, and where's the challenge in having a huge camera that you're expected to get great results? I'll probably never buy a lens for $1000 or more. I like the small cameras and lenses as they give me limitations and I can improve that way. If one day I NEED the latest and greatest that ONLY FF can do, I'll rent it. The rest of the time, I look for great bargains on M43 lenses. In most cases, I end up making money on them as so many people out there don't know how to sell their gear. It can be fun too trying out old stuff. That's how I got my $40 GM1 and $60 GH2 (great and fun backup cameras for me). Personally, I get a rush out of creating cool content on other people's old stuff.

    Why wouldn't I go APSC? Lenses. Except Fuji, no one has anywhere near what M43 offers. And Fuji lenses aren't really made for video AF. Also, they're rather expensive as they're the "hot" new things whereas people are dumping their M43 systems for nothing sometimes because they often (unwittingly) think FF will save their photography/video skills- been there, done that.

    Same boat for me, size is my number one request. Never forget my last trip, one GX85, one LX100 (for my wife), the Panasonic 12-32 (what a gem), 45-175, 42,5 f/1.7, and a Rokinon 12mm f/2. Never felt the need for something else, and everything packed in a little messenger bag. 

    Moved to Fuji because of the (in my opinion) the future of the format (not by quality, but because of the FF craze), because Oly and Panny were never sold officially here in Brazil (almost all my gear was bought in trips in another countries), because Fuji have kind of good body prices in comparison (we have a 60% import tax, cameras are usually double the US price, and some Fujis are sold here 30-50% higher "only"), and, ultimately, because after m43, is who have the smallest lenses.

    The 18-55 f/2.8-4 zoom is indeed very good for video, the Nocticrons are small and good enough from my needs, the 55-200 have a good size and is very sharp, and got the Rokinon 12mm again. To make it closer to my old m43 system, got a Viltrox 85 f/1.8 to replace the (motferf*cking amazing) Olympus 75mm f/1.8. 

    Zero interest in full frame, because of lens size. Ok, I could play the equivalence game, getting slower lenses, but these tend to be rather lackluster - is some FF system make a buch of very small f/4-5.6 lenses with good quality, maybe I will go there (but I doubt).

    For me, I trade size and discreetion for absolute quality.
