  1. If it helps you decide, I use V30, 90MB/s write, 160MB/s read speed rated SanDisk Extreme 128 GB micro-SDXC cards (in SD adaptors) in my Lumix G9 for 150Mbit 4k50p with no problems. Recently I've paid around £23 for these in the UK. There are also equivalent standard SD card size versions. The (theoretically) better 'Extreme Pro' versions of these (similar performance) can sometimes be bought for not much more if you shop around. V30 rating = 30 Mbyte/s = 240 Mbit/s sustained sequential write speeds, so 200 Mbit/s 6K HEVC is theoretically OK. Personally I've always found the higher grade SanDisk cards to perform well i.e. read and write speeds are at least as good as the spec.
  2. I think of all the video-capable cameras I've owned, the Pana G6 (which Andrew dubbed the 'GH2 Redux' when he reviewed it) was almost perfect for me - small, light, fits nicely in the hand, mic input, FHD 50p/60p to MP4 files, a lever to control power zoom lenses (the last G series camera to have that), 'creative video' mode etc. and a simple uncluttered control layout. For stills (not video), it also had variable telephoto sensor crop controlled by the zoom lever. It's successors gained 4k video and then IBIS, but I think they lost some of the 'only what you really need' control simplicity along the way.
  3. I think that's a great idea !!
  4. Definitely - especially at the price they've dropped to (currently under £900 including sales tax for a new body in the UK). The used prices seem to be rising a bit too, which is interesting - some people must have realised just how much camera you get for the money...and that there is a great selection of good & inexpensive native lenses to go with it.
  5. Olympus 3840 x 2160 at 24/25/30 fps is about 100 Mbit/s => 12.5 Mbyte/s. At 4 Gbyte per file and 13 files, that works out at just under 70 minutes maximum 4k recording time (and much longer in 1080p)? The E-M1 ii is also limited to 13 files per recording. As I rarely record for longer than 10-15 minutes, enabling focus-stacking (on E-M1 ii) with any lens is of more interest to me, but as I don't have > 30 minute recording on any other camera I own, having it available on my E-M1 ii might be useful one day Thanks - I'd seen that info posted on EOSHD a while back (maybe by yourself) but not yet tried it with a recorder.
  6. Modern de-interlacers are adapative, so they use different combinations of techniques in different parts of the frame, depending on things like how much motion and inter-field differences there are. For DV I use command line FFmpeg to deinterlace (using 'yadif'), upscale and sharpen - in the example command lines below input is DV avi, output is H264+AAC audio at 1920x1080p at double the DV frame rate (so 25 fps interlaced -> 50 fps progressive): ffmpeg.exe -i <input_file>.avi -vf yadif=1,scale=1920x1080:flags=lanczos+accurate_rnd+full_chroma_int+full_chroma_inp,unsharp -c:v h264_qsv -global_quality 30 -look_ahead 1 -c:a aac -b:a 384k <output_file>.mp4 You can add motion-compensated de-interlacing 'mcdeint' to the processing, which improves the deinterlacing quality but is quite a bit slower: ffmpeg.exe -i <input_file>.avi -vf yadif=1,mcdeint=0:1:10,scale=1920x1080:flags=lanczos+accurate_rnd+full_chroma_int+full_chroma_inp,unsharp -c:v h264_qsv -global_quality 30 -look_ahead 1 -c:a aac -b:a 384k <output_file>.mp4 (I'm using nVidia hardware H264 encoding for the output in the above examples - h264_qsv - but you could use any of the many FFmpeg software encoders instead e.g. ProRes etc.) I got some of the ideas for the deinterlacing settings from here: https://askubuntu.com/questions/866186/how-to-get-good-quality-when-converting-digital-video
  7. For anyone with an E-M1 ii, someone has managed to modify the v3.4 firmware to remove the 30 minute video record limit and allow focus-stacking (for stills) with any lens - https://www.mu-43.com/threads/modified-firmware-looking-for-users.99804/post-1449131 I've loaded it on my E-M1 ii and the focus-stacking certainly works with Panasonic lenses. Not yet tested > 30 minute video recording, but the display certainly shows more than 30 minutes available. (There are also modified firmware versions for some other Oly cameras at the beginning of that thread e.g. for the E-M10 iii and E-PL9, plus earlier E-M1 ii firmware versions - see https://www.mu-43.com/threads/modified-firmware-looking-for-users.99804/post-1184700 ) I dipped a toe in the Olympus pool by getting a used E-M1 ii about a year ago (I own several Panasonic cameras as well). It's grown on me over time - relatively small, great colours, IBIS and build quality, but the differences/restrictions in how it operates in video versus stills mode get frustrating at times (like no 5x5 focus areas in video, and the single centre focus area is larger). The audio pre-amps are noisy too. It feels like there is a better video camera lurking in there but Oly have never really been interested/committed enough to video to let it out...
  8. The GH5s and G9 have more recent, faster processing than the GH5 - hence there have been more performance upgrades via firmware updates for those two versus the GH5. I guess the new GH5 ii probably has (at least) the processing and IBIS from the G9 combined with the better thermal management of the GH5 to allow unlimited recording times.
  9. My guess is that (to record internal compressed raw) either RED want an exorbitant licence fee or they won't licence it all - unless, like the deal with Canon where they get the RF mount licence, they get something useful for their own cameras in return i.e. it's a cross-licence deal (quite common in terms of patent licencing). Re. today's other Panasonic announcements, as a G9 user I'm quite pleased it's getting a firmware upgrade to add the latest AF algorithms and the 'red frame' recording indicator from the S5. The GH5s is getting the same update plus raw video output to Atomos (for ProRes RAW).
  10. Just a quick thought - have you tried setting 'i.Dynamic Range' to off (or low)? (in the 'Photo' -> 'Image Quality' menu, but also applies to video - see page 353 of the user guide) It's disabled automatically in the V-Log/Like709/HLG etc. modes. I'm not an S5 user, but I know from experience with the G series Lumix cameras that 'i.Dynamic Range' can make low-light video look a bit noisy/flickery (so the usual recommendation is to set it to off or low).
  11. AFAIK, some S5 10-bit modes have a 30 minute limit per clip, but 8-bit doesn't.
  12. Not surprised - as an owner of a G85, I know it's a great camera for the money (and size/weight) but when I bought a G9 I realised what I'd been missing...
  13. (Speaking as an electronics engineer) the turn-on problems sound like the extra 'startup' current drawn by the phantom power circuitry on power-up (if it's on when the XLR module powers up) is 'tripping' some protection system - which then cuts off the power to the XLR module because it thinks it's faulty. 'Staging' the power up by first turning on the module (with phantom power off), then turning on the phantom power probably keeps the peak 'startup' current draw low enough to stop the protection tripping. Unfortunately I think the only way to find out if it's the XLR module or the S5 having a problem is by trying another XLR module or S5.
  14. S1/S1R/S5 updates officially released now - https://av.jpn.support.panasonic.com/support/global/cs/dsc/download/index4.html
  15. Weighs almost nothing as well - it's my 'carry in the bag just In case' low light lens.
  16. AFC on the 20mm pancake is slow and noisy (I own one). Have you considered the cheap but good Panasonic 25mm F1.7? At the wide end, Samyang/Rokinon do an inexpensive all-manual 12mm F2. There are also 12, 17 & 25 mm Olympus primes, but no personal experience of those.
  17. I own both a G9 and an EM1 II and honestly I'm not convinced that (overall) the Oly autofocus is much better than the G9 - and IMHO the G9 is a much better overall video camera than the EM1 II. The G9 1080p leaves the Oly 1080p in the (soft) dust, then add 4k50/60p and 10-bit video modes which the Oly hasn't got at all... On the other side, the Oly is nice to use, has great IBIS and battery life, and is smaller and lighter than the G9.
  18. There is always '4k photo' mode on the GX800, which allows PASM modes - 30p only though, and I think all 4k is limited to 5 minutes max per clip.
  19. Nikon has officially announced the development of the Z9 - https://www.dpreview.com/news/7215673224/nikon-announces-development-of-flagship-mirrorless-z-9 From the dpreview news item:
  20. ...where he says it's HEVC (H.265), 4:2:0, 10-bit at 200 Mbps, which is the same as on the G9 (and I assume the GH5). So 10-bit 18 Mpixel stills...
  21. If it's like the '6K photo' mode on my G9, the files are H.265, 10-bit, 4:2:0 at 200 Mbps (info below - from the VideoRedo editor - for 3:2, 30 fps capture), with AAC audio. It uses 'long-GOP' encoding, but the GOP is quite short, only 16 frames, with only has IDR and P frames (no B frames) according to VideoRedo. If you want to upload a short clip from the S5 (a few seconds is enough) I'll check the parameters for you.
  22. From a earlier post in this thread (for video AF-C):
  23. If you can live with M43, then add the Panasonic G9 to the list - 10 bit video support and excellent IBIS, with 1080p and 4k video quality comparable to the GH5 (albeit without All-I codecs and limited to 30 minutes - 10 min for 4k60 - record time). It's a bargain for what you get...around £700 used, £900 new in the UK at the moment.
  24. I think a lot depends on your 'use case' - personally I don't need to focus-track people/faces or use shallow depth of field very often, and I find the G9 video C-AF to be perfectly usable for the sort of outdoors run-and-gun handheld filming that I do (as an amateur). It helps that I almost always shoot at 50p/60p which definitely makes DFD work better.
  25. No - that's one of the main differences between the G9 and the GH5. There is a hack to temporarily remove the limit in this YouTube video - https://www.youtube.com/watch?v=0qzBWdaY634 - but I've not tried it as I've never found the 30 minute video limit a problem (or the 10 minute 4k60p limit). I usually film hand-held, and 10 minutes is a long time to hold a camera still anyway
