  1. 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.
  2. 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.
  3. 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?
  4. Wobbling is certainly if not most apparent and annoying, if it exists, for static shots. I can't help out below 24.

  6. Example with Canon RF 24-105 IS STM lens:
  7. Overheating and the time limit are both now irrelevant if the R5 is combined with the Ninja V+. I think the IBIS wobble was confined to an EF lens with IS, the EF 16-35 L. I don't see it in videos I have shot, with an RF lens with IS.
  8. Point? How about points! The R5 has 8K RAW, it has lower rolling shutter, it has better AF, it has better stabilization, and it has better 4K, in HQ mode (sampled from 8K). With overheating solved using the Ninja V+, it seems there is no contest. Am I missing something?
  9. I have rigged the Zitay CFExpress to SSD on my R5 for handheld work with a 1 TB Samsung 980 Pro SSD. It works fine at the highest bitrates (8K RAW) and the CFExpress "card' plugs into any CFExpress reader and the transfer rate from the SSD is the same as if it were a CFExpress card (400 MBps). The combo is a significantly cheaper alternative to any 1 TB CFExpress card that has the capability of the 8K RAW bitrates (few do - Canon has a list). I did not find it awkward to use it in the field. But out in the sun I do not think this rig increased time to overheat. Thus, I do not think the CFExpres card is an important source of the heat issue. So, a cheaper alternative for high-capacity fast storage but not a heat saver.
  10. You can shoot in RAW or RAW light, and both can be edited using the RAW panel in DaVinci Resolve with full controls, including ISO and temperature. For workflow, the R5 can shoot RAW and proxies simultaneously, making it very easy to edit with proxies in Resolve - you just link the RAW clips to the folder with the proxies made by the camera. The RAW clips are recorded on the CFExpress card, the proxies on the sd card. Yes, the proxies have the same name (different extension) as the RAW clips. Two examples: And, no, the camera did not overheat in the bright sun (75+ F).
  11. The R5 comes with a cable holder that locks the HDMI cable to the camera. There is no electronic issue with micro or mini HDMI. You can record 8K 12bit and 4K 120p ProResRAW with the Ninja V+, and there should be no overheating. You can record 10bit 4K 60p ProRes 422 HQ with the Ninja V and there is no overheating.
  12. Yes, I have used the EF 35mm f2.0, EF 28mm f2.8 and EF S 18-135, EF S 10-18, EF S15-85. All work well with the MC21 adapter - stabilization and push-to-focus-AF. Examples:
  13. This commissioned skateboarding video was shot using the fx3, but it used the features that the a7s iii has: 120p 4K, all intra-codec to minimize motion artifacts, IBIS, good AF, and the parfocal behavior of the 28-60mm lens. The expressions of the skateboarder as he fails over and over and then nails it, twice, are the foci.
  14. Here is a GoPro Hero9 Shot in 5K Linear Mode + Horizon levelling. Note that Linear mode crops and horizon-leveling + stabilization crops even more. So do not expect 5K resolution. This was shot in 5K and rendered in 4K: This was shot in 5K Wide with stabilization high only and rendered in 5K:
  15. No, sorry. The lens cover comes off, not the lens. On the Hero8 the lens cover could not be removed.
  16. I have the EF S 55-250mm, the EF 24-105mm f4 L lens and the EF S 18-135mm lens. The 18-135mm has much better stabilization and a better range for use on a crop sensor camera than the 24-105. The EF S 18-135mm in fact has a "nano" motor, which is supposed to have the best features of STM and USM, so it is both quiet and fast for AF (better than either STM or USM). It is a unique lens, and you can also make it a variable-power zoom lens, with a Canon attachment (small). That seems ideal for shooting sports action. As a benchmark the 55-250mm STM also has better stabilization than the 24-105 L lens.
  17. First, a mechanical shutter is irrelevant for video. And second, the fp does come with a cold shoe attachment. Why is a *hot* shoe important for video? So, yes, the fp is really a video camera. And this new Sony is much inferior in that dimension, unless you insist on continuous autofocus...
  18. No, the Sigma fp is clearly the tiniest cinema camera on the market, and it is full frame besides shooting DNG RAW internally.
  19. While we are on the wish list for lenses from Sigma: One of the key advantages of the Sigma fp is it is small. A disadvantage is it lacks in-body stabilization. But, most Sigma lenses are big, as was said, and most also lack stabilization. To use the fp handheld for video, small lenses with OIS are needed. Right now, one really has to use Canon lenses for that.
  20. First, it is silly to say that any aspect ratio, sensor size, etc. is necessary, so let's not waste time saying FF is not necessary. Of course it is not necessary. And one cannot generalize whether FF is "needed" or "important" either - depends on what look you want. So, debating what is needed is a waste of time too. Second, the Sigma fp is a cinema camera, and it shoots full frame and APS-C. No need to switch cameras. to choose S35 or FF. One may not like the camera for other reasons, so there is the Sony Venice... In any case, having a FF cinema camera that has the option of crop mode, is better, all else the same, than having an S35 cinema camera because it provides more creative options. I do not think that is debatable also. You could say all else is not the same - lenses larger, etc.
  21. While we are on the wish-list route, I vote for 4K60/50P. Slow motion is important, and used in many creative videos and film. 60P is also good for fast moving subject, sports, action etc. Z Cam, new Sony, Panasonic, Blackmagic all have this option for either RAW or at least 10bit color. Sigma fp lags behind in this dimension of video capabilities. And, btw, the FullHD 120P in the Sigma fp sucks, RAW or not. Everyone agrees. So, not line-skipping, pixel-binning 4K60P.
  22. Maybe I am missing something, but with a full-frame camera you have the choice of shooting in APS-C or full-frame with a full-frame lens, right (true for the sigma fp and the Nikon Z6, for examples)? Then you can choose the look, lens and capabilities depending on the scene. Some movies change aspect ratios, why not FF and crop aesthetics too?
  23. Ok, here is an uploaded 6K test video, which you can view up to 5K (2880P). Looks good to me on my 4K and 1080 screens compared to the original, which has a600 Mbps bitrate!, or any video in terms of color and resolution. This was shot in BRAW with no additional sharpening.
  24. I shoot with the fp almost exclusively wigh Canon lenses. All work fine (IS, AF), but some perform better than others - faster AF. Performance is similar on Canon bodies, except no AFC in video mode with the Sigma adapter. Ask me about specific Canon lenses, as I have a bunch, and I can tell you about my experience (I shoot only RAW video).
