  1. If Panasonic removed the mechanical shutter, would there be enough room for a built-in ND filter?
  2. It looks like to could be a GH5s https://www.43rumors.com/ft3-panasonic-gh5s-coming/
  3. The iPhone 8 has the same size sensor as the 7. http://www.techinsights.com/about-techinsights/overview/blog/apple-iphone-8-teardown/ "The wide-angle Sony CIS has a die size of 6.29 mm x 5.21 mm (32.8 mm2). This compares to a 32.3 mm2 die size for iPhone 7’s wide-angle CIS. We fast-tracked the die photographs for this teardown blog so didn’t record the color filter images today, however we can confirm a 1.22 µm pixel pitch."
  4. This iPhone 8 teardown has confirmed that the pixel pitch of both the wide and telephoto sensor is the same as the iPhone 7. http://www.techinsights.com/about-techinsights/overview/blog/apple-iphone-8-teardown/
  5. The below sample image from the iphone 8 has the same 3.99mm focal length as the iphone 7. That would suggest the sensor size (1/3") has not changed, so I would not expect much improvement in IQ.
  6. New spec just added to rumor. New: 4k UHD video in FX format (with no crop)
  7. Anamorphic squeeze update. http://www.43rumors.com/panasonic-is-working-on-a-de-squeeze-for-the-anamorphic-modes-in-the-gh5-to-be-released-this-summer/ “…We put pressure to our devs to put a proper de-squeeze for the anamorphic modes in the GH5 (let’s hope for it in the summer firmware update that’ll bring 6K anamorphic)…”
  8. It looks like Fuji might be jumping into video big time. http://www.fujirumors.com/fujifilm-working-ultimate-5000-aps-c-x-trans-x-series-camera-also-video-grain-salt/
  9. Sony just announce their new phone with this sensor. We'll likely see other phones with this sensor later this year. https://***URL removed***/news/7636712678/sony-xperia-xz-premium-features-960-fps-slow-motion-and-4k-display
  10. Keep in mind that the UHS-II standard was announce 6 years ago and there are still only a handful of cameras that can support even half the write speed capabilities of UHS-II. Based on the current trajectory it'll take another 5 years to get to 300mb/s write speed.
  11. And UHS-III was just announced yesterday, supporting up to 624mb/s. https://www.sdcard.org/jp/downloads/pls/latest_whitepapers/Understanding_the_NewUHS3_WP_20170223.pdf
  12. Yes, the XQD results are much faster but that just confirms the limitation is not CPU but the camera's hardware interface to the SD card. http://www.cameramemoryspeed.com/nikon-d500/sd-and-xqd-card-speed-test/
  13. The Lexar 2000x supported a max. write speed of 260mb/s in 2015. Tests have shown this write speed to be attainable with a card reader. The problem today is that cameras are still not able to take full advantage of this write speed with the E-M1ii and D500 topping out at 163mb/s. http://www.cameramemoryspeed.com/reviews/sd-cards/lexar-professional-2000x-uhs-ii-64gb-sdxc-memory-card/ I am not sure if this is a processor limitation or card hardware interface limitation. But considering the very similar results results between the E-M1 and D500 it looks like they are using the same hardware to read/write to the card. I suspect there are only a couple of 3rd party companies supplying this hardware and that is where the limitation lies.
  14. This person posted some of his experiences with the handling of the E-M1ii and the GH5 for video. https://***URL removed***/forums/post/59100667
  15. This 1/2.3" three layered stacked sensor looks interesting for the next versions of s http://www.sony.net/SonyInfo/News/Press/201702/17-013E/index.html
  16. It looks like Panasonic may have implemented the sensor differently and has focused more on high ISO instead of DR. https://fstoppers.com/originals/everything-you-might-not-know-about-gh5-162773 "the native ISO is 400. It was confirmed that by going down to ISO 200 you’ll lose about a stop of dynamic range since it’s an extended ISO."
  17. I found this 83 page detailed presentation on the GH5. I apologize if it has already been posted. http://www.personal-view.com/downloads/GH5_Presentation.pdf
  18. Ctein just post a good overview of the DxoMark testing that better explains what I tried to say. I didn't even realize that Olympus has an Exposure Compensation menu setting that allow you to alter the Olympus default. https://www.mu-43.com/threads/dxo-mark-just-rated-the-e-m1-ii-impressive-results.89224/page-3#post-975746
  19. By default Olympus is using the lower noise floor of the sensor to extend highlights instead of reducing dark noise. DPReview is using the default underexposed RAW file from E-M1ii. Adobe automatically increases exposure when brought into LR which is why they seem to have the same exposure. DXOMark measures the noise for all sensors at the same brightness (18%SNR) and that is where the noise is similar to the D500.
  20. We can already see from DXOMark and from other tests what Olympus has done with this sensor. Olympus has decided to use the lower noise to provide more highlight headroom. They are underexposing the image in RAW while converters such as Adobe are reapplying the exposure back in. The end effect is much less chance of highlight clipping while the low level noise is not improved over the older sensor. I presume Olympus is doing the same with video. You can always adjust the exposure to change this. The GH5 may implement this sensor differently. Here is one RAW example comparing the E-M1 and E-M1ii that shows this (about half way down the page). http://mirrorlesscomparison.com/olympus-vs-olympus/omd-em1-vs-omd-em1-ii/ https://photos.smugmug.com/2017/Comparisons/Cameras/EM1-vs-EM1-II/Image-quality/i-ZL92Qfc/0/XL/em1-vs-em1-ii-DR-E-M1-2-XL.jpg https://photos.smugmug.com/2017/Comparisons/Cameras/EM1-vs-EM1-II/Image-quality/i-G4LHrtK/0/XL/em1-vs-em1-ii-DR-E-M1-II-2-XL.jpg
  21. The DXOMark results from the E-M1ii also seems to suggest a base ISO of 400 as there is no additional DR at ISO200. https://www.dxomark.com/Reviews/Olympus-OM-D-E-M1-Mark-II-sensor-review-New-standard
  22. I am sure that this will be somewhat controversial but DXOMark posted a score of 80 for the E-M1ii. The graphs provided the most interesting information. https://www.dxomark.com/Reviews/Olympus-OM-D-E-M1-Mark-II-sensor-review-New-standard
  23. That would make sense since a 3x crop would give you 1920x1080. Keep in mind that the available options refer to the final output after the crop.
  24. I wonder if the option to prioritize FPS over stabilization suggests that IBIS would be less effective with 4kp60. It would not surprise me to see IBIS disabled on the GH5 when using 4Kp60. Did you get a change to try out the "almost 3x" Movie Teleconverter? The ~3x crop suggests that Olympus is pulling a 1920x1080 crop from the centre of the sensor so the quality could be comparable to a crop from C4k. If 60p is available with this crop then it could be useful for some wildlife videos.
