    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?

  4. 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.

  5. 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.

  6. 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.

  7. 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)"

  8. 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).

  9. For instance, their 45-175 with power OIS, which I have, has substantially better stabilization than the 100-300. And, as soon as I can go to a store to test it out, I'm going to take my 45-175 with me and compare the OIS to IBIS (without digital) at 175mm.

    ​I've done it once with my 45-175mm and my E-M10 (just 3 axis IBIS). At least for still, looking in the EVF while framing, the IBIS in the E-M10 looked a little bit more stable compared when I turn off the IBIS and use the lens OIS.

  10. ​Have you shot with the NX1?  i find that using a finder on the back screen same as the NX500 has i never need focus pealing to get good focus. In fact when i do turn it on it is more in the way they anything. The back screen is very clear and easy to focus with. I use a 3x finder on the back.

    ​Never used the NX1, but I use peaking in my Panasonics. For fixed shots (where I don't change de focal distance I think that the enlarged view is ok - even preferred), but when I have to change focus while filming, pressing a button to bring the enlarged view (if you are working with non-native lenses) could introduce some shaking in the camera; I got better results with peaking.

  11. Even with the limitations it stills seems like a great deal. It's only €749, including a lens!
    Cheapest 4K camera on the market, and everybody expects it to have all the high end features...

     

     

    ​A lot of cheaper cameras have focus peaking. The 4k crop could be understandable because of processing / heat issues / market segmentation, but no peaking in 4k s a very BIG flaw.

  12. Well, no focus peaking in 4k was the final deal breaker for me - more than the crop factor. A shame, since the first samples that people are putting in youtube have very good resolution.
