  1. Unfortunately, looks like that no IBIS on the GH5 - IBIS was extensively mentioned in the G80 announcement, and since IBIS had disappeared in the last rumors about the GH5 (and the rumours are right in almost all of the other features), I guess that no IBIS in the camera.

    Maybe the line of thought (or line of excuse) from Panasonic is that this is a "camera for professionals" (it was very highlighted in the press conference, mentioned a lot of times: GH5 is the professional camera, the G80 is for enthusiasts); no other "professional" cameras (Canon's C-line, Red, Blackmagic, Arri..) have IBIS,and they will probably say that professionals could get better results with gimbals or steadicams (not that I agree with them). "Oh, run and gun"? Use the G80 or the new FZ2500 (which even have V-log now as a paid upgrade). That will probably be their excuse (the real reason could be avoiding any more heat around the sensor - the camera still have no fans).

    If they are right or not, only time will tell.

    I think that the sensor is not new too - it's the same 20mp sensor from Sony. Albeit with some improvements (the sensor is in the E-M1 MKII and Olympus are saying that it have a 1-stop gain). The press release mentioned "6K photo (18mp)", that is the marketing gimmic that I mentioned some posts ago.

    Apart from that, the camera looks awesome. And the joystick to change the focal point is very interesting for stills (and was a surprise).

  2. About 6k: since it is (now) mentioned as a "photo mode", probably they are considering it in a 4:3 aspect ratio - than the quantity of pixels is approximately the same of a 6k DCI image (and sounds better for marketing, and is in line with Panasonic 4k photo modes).

    My concern it that IBIS was not mentioned in the specs...

  3. My two cents about the camera (that I have no intention to buy, by the way):

    - It just made clear that, for Canon, if you want a serious camera for video, you will need a C line camera, DSLR video was an accident. Nothing new;
    - Hence, it is a stills centric camera (and for stills looks like a very good one), with some video features for less demanding needs, especially events;
    - I think that is no coincidence that a lot of previews that were appearing in various sites features opinions from event shooters - especially wedding ones. And for event shooters, turnaround time is crucial - this means less file transfer times, colors right (or almost right) out of the box; it is an area where 1080p is still the king. In event shooting rack focus manually is a problem - lots of movement without stage marks and coordinated positioning, and in this conditions the Dual Pixel AF is a godsend. For them, the MkIV probably will be a very practical camera - and I guess that is a market that sells more than specialized movie shooting.
    - A question: it is not possible for Metabones to make a focal reducer EF->EF just to get the full frame circle from EF lenses and reduces it to the 1,74x crop? I know that it was not possbile in the NX mount, but if they can do it for the EF...(if Brian Caldwell is reading this, maybe he can answer that)...

    Yes, for video, is a deception for a lot of us - but will make sense for a lot of people, will be an "enough" camera and easier to use with the Dual Pixel AF. And will sell like hotcakes.

    If Panasonic decides to upper their game and make the GH5 a true video centric camera, they could go for the A7S route and offer it with a 12mp S35 sensor (or even a m4/3 one) - less data to process for 4k, and much more sensitivity in low light (for me, the main problem with my m4/3 cameras), and leave the true hybrid role for a G8 camera with a 16 or 20mp sensor. But all the rumours says that it will have the 16mp sensor from the GX80.

    Do others concur that Panny has inherent judder during pans compared to others? When I see it on the web I assume encoding/connection etc.

    Regarding the clips above, the highlight handling in the windows seems good.

    I was worried about the jitter, thinking that it could be something GX85 related - but then I saw some GH4 past footage from Andrew and saw the same jitter in pans  / people movement:

    Anyone knows whether is possible to get rid of this annoying "change your focal length" popup each time you turn on the camera when using a manuall lens that does not have any electronical contacts? really reminds on the NTSC mode on Sony cameras..

    I LOVE this feature on my GX7 - for stills. When using my EM5 II for stills, I change the lenses a lot, and when using some manual lenses I almost always forgot to change the focal length.

    For video, yeah, could be kind of annoying - but since it is only a confirmation and ready to go, for me is a good trade off.

    Confirmed. For power, you need the same gx7 adapter.

    Thanks, John. :)

    Are you getting the jittery footage that I saw in some videos when panning? It is not the "shaky" movement when the sensor tries to compensate the start / end of the panning, looks like that it interferes with the video cadence...

    The video from alanpoiuyt in a previous post shows it clearly, starting at 0:15.

    I am almost totally happy owner of the Sony a5100 and I only complain about that it can't be powered externally (like the GX80 does) and, a lot more annoying, about the overheating issues.
    Does the GX80 overheating issues?

    I guess that Gordon at Cameralabs told that the camera could only be charged by usb, not powered - the usb only could be used for charging with the camera switched off.

    Andrew, could you confirm this?

  7. Don't expect a S35 or exotic sensors in the GH5 - probably will be the 20mp sensor from the GX8 and Olympus Pen F. They are with the hands tied by Sony - Panasonic was not developing sensors from a long time, just recently they started again (read it somewhere). The organic sensors are still in the future too, I guess. PDAF is probably out, too - looks like that Panasonic bets all in the DFD technology.

    The only way to improve the low light perfomance with the current tech is to go the BSI way; but Sony is holding the technology for their cameras - their clients are not receiving BSI sensors, only the Sony cameras. Samsung is the only other sensor manufacturer that makes a large BSI sensor (in the NX1), but looks like that they are out of the game (a GH5 with a Samsung BSI sensor would be great).

    The A6300 might be a low light monster - if the BSI tech in its sensor is the same from the A7RII, the pixel pitch of the sensor will be even greater than the A7RII.

  8. Unless Nikon has no plans to introduce a new camera with the "newly acquired" Samsung tech until next year, then I would assume they are only sourcing the sensor. It takes time to implement this technology into their current facilities and design. 

    Chipsets tech too - almost as important as the Samsung's sensor tech. Remember, the NX1 samples a 28mp sensor, full readout, at 120fps, and encodes it in H.265 (that needs much more processing power than H.264) without transforming the camera in a ambient heater. And the use of Tizen as the camera's operating system.

    I think that Samsung's tech in the processing pipeline (sensor + chipset) is leaps ahead of everyone else, including Sony.

  9. Panasonic are in danger of being overtaken by competitors taking away their unique selling points.

    If the next Olympus OM-D E-M camera gets 4K as it likely will and with their market leading IBIS system, then the GH5 is going to have to do something pretty damned special (like go Super 35mm and ProRes) to make me want to use it over the E-M2.

    I'll give you another example...

    The GH2 used to have a big video quality advantage over Canon, Nikon and Sony DSLRs. It is why I bought it.

    Can anyone seriously with a straight face say that is the case now with the GH4 vs A7R II?

    ​But Olympus must break on of their "barriers": supply good video. They had the time to do it with the E-M5 II and failed VERY badly. 

    And since both Oly (cumbersome menus, subpar video, same idiossincrasies generation after generation - like underexpose in TTL flash) and Panasonic looks like have some points that they never address, I'm not much positive about a future IBIS in GH5. Two years after the GX7, and they can't produce a working IBIS for video.

    More worried about the new sensor - Sony could be taken both Pany and Oly hostages by sensors. This unit is not BSI, no improvements in high ISO (same perfeormance as the 16mp sensor, which is a relative gain, but relative to the resolution, not in the final image), and no fast readout enough to eliminate crops in 4k; if this will be the base sensor for the GH5 and E-M1 mkII, then Sony left both almost one and a half generation behind.

    The incredible 1" sensors from the RX100 IV and the RX10 II have a 6 month exclusivity clause for Sony - they probably will sell them in boatloads in this period. For bigger sensors, could be even worse - BSI could remain an exclusivity to Sony, if the GX8 sensor is an example. And Sony will have a generation gap to control.

    My suggestion: Olympus, Panasonic and probably Fuji (and maybe even Nikon and Canon) must have urgent talks with Samsung about sensor supplying. The NX1 sensor is BSI and very good as we know; a Samsung m4/3 BSI sensor, with higher sensitivity and very fast readout (remember: the NX1 have an APS-C 28mp sensor in full readout at 240fps) would be killer, and stops the hold that Sony could put on the sensor market.

  10. About the high framerates of the smaller cameras: yeah, it is upscaled. Full specs of the 3 cameras are already up in Sony's website.

    From the RX10 II page, in the HFR section: http://www.sony.net/Products/di/en-us/products/ht7k/specifications.html?contentsTop=1

    "<Sensor Readout Number of effective pixels>
    Quality Priority:240fps/250fps (1,824x1,026), 480fps/500fps (1,676x566), 960fps/1000fps (1,136x384)/Shoot Time Priority: 240fps/250fps (1,676x566), 480fps/500fps (1,136x384), 960fps/1000fps (800x270)"

  11. I've used legacy lenses with my GH2 (and with a Olympus E-P1 in the past for stills) without peaking, with very good results. But a shoot a lot in live concerts, with poor lightning, and in this conditions peaking helps a lot compared to using a loupe in the LCD (I have one too).
