  1. I was shooting in the sun for 3 hours, getting about 30 minutes of 5K RAW video clips.
  2. Here is a test video of the AF capabilities of the RF 70-200mm f4 L lens: tests of par focal zoom, focus pulls, focus shifts. In 8K: Mics are on, so you can hear if there is any stabilization or AF noise.
  3. 5k60p RAW is a crop of the sensor. 8k RAW to the Ninja V+ is 10 bit, while internally it is 12bit.
  4. I'll bite. I can shoot 12bit 8K DCI RAW internally with my R5. Why do I need this? And, no, I do not experience overheating problems (though I have to be mindful). And, right now one cannot record 8K on the Ninja V+ with the R5. There still needs to be a firmware update. So, no one can report the advantages, if any.
  5. I can beat that! I edit 8K 12bit RAW videos on my 8GB MacBook AIR M1:
  6. Both shot in 8K RAW. Edited in Mac Mini M1 using Resolve Studio.
  7. Just to be clear - you can use C1-C3 for video in the R5. And dual slot recording will be in the next R5 firmware update (now you can "only" shoot 8K RAW in the CFexpress slot while simultaneously recording 4K IPB H265 10bit 4K in the sd slot). And 8K RAW via HDMI also in the R5 firmware update.
  8. Apple M1 chip hardware decodes 10bit H265 4K or 8K 422, and the clips play smoothly in Resolve and Final Cut Pro. No Nvidea graphics card hardware decodes 10bit H265 422.
  9. Another outing in hot sun shooting 8K RAW:
  10. It is the same lens - it's in the title of the video! I don't not know what "more movement" means. I will not walk with the camera - that produces unwatchable video. I tried it. Has nothing to do with "wobble." IBIS/OIS cannot deal with walking on any camera. I panned up and down. Besides wlaking with teh camera, which I will not post and is awful, what movement do you need to see? If just 3 seconds of one shot has wobble that you can see, it cannot be IBIS-induced wobble. It's just my inabiulity to either pan smoothly or hold the camera still enough. Last, this lens at 16mm sucks - it is significantly distorted at the edges. That is a first-order problem. Wobble seems, loking at these results, trivial.
  11. This has some pans, horizontal and vertical. 4K DCI, almost all shots at 16mm, with one crop shot at 35mm (so 1.5X). I again do not see any evidence that there is something peculiarly wrong with the IBIS/OIS of this R5/lens wide-angle combination. At 16mm, the lens is, however, highly distorted - when one pans the distortion creates odd effects, but they are not wobbles and it is a lens optical fault.
  12. I will try some panning/following. But in advance, whether IBIS on any camera should be on for panning is debatable. IBIS resists camera movement, thus it may try to counter any movement, including purposive movement like pans. Many videographers recommend turning IBIS off for pans. And this has nothing to with the R5, just the nature of IBIS, and technique. I do not do much panning (I find pans to be ugly in any video/movie unless done sparingly and by pro's). Following people is a good use, but that is not something I normally do with a 16mm lens! Btw, the 16-35mm lens (EF or RF) is quite ungainly. It is a long, heavy lens that is in fact difficult to hold steady. It also looks like a telephoto lens and thus makes people very nervous in crowds, even though at 16mm no individual matters. They just think a long lens is pointed at them.
  13. I am going to post my own Wobble test! I used the Canon EF 16-35mm L lens (and EOS adapter), with IBIS and OIS handheld, almost all at 16mm and using 4K DCI HQ so the full width of the sensor is used. It is uploading now. Static images, of course. But it seems to perform just as well as the 24-105mm, 35mm, 50mm lenses I have used. But, you can see for yourself. So, don't leave yet...
  14. Thanks. But, exactly - fail! That does not meet my standards for steady handheld video walking while shooting (forget the wheelie stuff). It is impressive, though. And you are right, he does not have the technique as the up-and-down is visible when he walks. Of course, stabilizing a tiny sensor, as in the cellphone, is much, much easier than stabilizing a full-frame sensor! Anyway, I trust you know what you are doing and need good stabilization. Let's hope that Canon fixes the glitch for the specific lenses you want to use. It is obviously not a total failure if the R5 provides the best stabilization for all lenses 24mm and above. The Sony A1, of course, provides mediocre IBIS for all lenses, but does not discriminate!
  15. I don't believe it - walking while shooting with or without IBIS that is smooth, so show us. I have plenty of experience walking while shooting with gimbals, and without. Ninja walk and all that. I agree that technique makes a big difference for walking while shooting, even with a gimbal. And even with a gimbal without technique, it is not smooth. So only with IBIS - not possible. But I am willing to be convinced. And all of the video that I posted is handheld, and steady. Just not moving with the camera, all static, like tripod but without one (which also takes technique.) Proper IBIS, beyond proper. An exception to *my* rule is the GoPro Hero9 Hypersmooth stabilization: Example of moving with the camera (and static) without gimbal:
  16. You cannot walk with any camera using IBIS and get acceptable stability. Your standards are low if you think so. If the wobble exists below 20mm for static shots, then there is a problem. But the problem is for specific lenses. But in any case you will never be able to walk or run or creep with a camera using IBIS and get results that rival a gimbal or would be acceptable to professionals. If you use a gimbal, none of this matters.
  17. No, I used IBIS and no wobble. I am not trying to sell you on this. You can see from my video the handheld stabilization is amazingly good. You made the claim on wobble, I am just guessing what the cause is if it exists. But, let's be clear - IBIS and OIS are for removing shake. They do not smooth while walking with the camera by professional standards for any camera - it works great for handheld static shots, as I have shown. If you move with the camera, you must use a gimbal - that certainly includes your iPhone. Whether IBIS helps or hinders gimbal stabilization is actually not clear for any camera. I have posted lots of videos, and none with wobble. So, is it a particular lens they used or what? I have also seen lots of R5 videos with no wobble, from videographers that know what they are doing. I agree, if there is wobble in static shots with some lens, it is a concern. So, let's get clear what is going on and what stabilization is actually needed.
  18. If you want to move with the camera, then you certainly need a gimbal, and you do not need IBIS or OIS, so no wobble induced by the camera or lens, if it exists. Even panning really does not need camera stabilization. Is it alleged that wobble occurs without IS?
  19. Wobbling is certainly if not most apparent and annoying, if it exists, for static shots. I can't help out below 24.
