  1. in the r5 watercooling video from diyperk, his internal temperature measurement showed a 83 degree temperature on the cpu board, if you keep on recording without cooling, won't the image sensor get warmer and start to show up more image noise as heat goes up ?
  2. good AF is a major selling point, most of the time we are fimling humans and humans move so with manual focus you never get the advantage of high resolution/sharp lenses with FF shallow depth of field as you are slightly out of focus 90% of the time
  3. the algorithm to convert raw data to uncompressed 8 bit is much less computational intensive than compressed 10 bit, not sure if this camera have enough computational power or good enough heat diffusion to handle that internally
  4. looks like a fresh new camera built from the ground up without the weight from the past so why did they kept the old outdated sd card media ? m.2 ssd are cheaper, faster and have a bigger capacity we are dealing with huge raw files after all so so why did they not put a m.2 internal ssd slot instead of a sd card slot ?
  5. when comparing a6600 to xt30 of course xt30 is cheaper and better in some aspects but what about the 10 min max recoding time in 4k vs unlimited recording ? you should not nitpick your arguments but rather give an honest pros and cons list and let us decide what compromise we want to make for our specific needs as unfortunately no camera has it all (though a73 is the closest to a good hybrid camera all rounder)
  6. just saying you could do it with a $1700 combo (CeyeAF with sigma 30mm f1.4) but you cannot do it with any other camera and wether you like it or not it gives intensity :
  7. the only great thing about a6600 you don't even mention is continuous eye AF in video, do you know another camera that can do that ? a f1. 4 closeup with the $289 sigma 30mm will open up the possibility of interview with nearest eye in focus and the rest of the face blurred - a very intimate image with cinematic intensity https://images.app.goo.gl/3A5aCA1CFmzxRsyXA
  8. true nikon and fuji were the only 2 makers not having a pro video line to protect but the survival window is getting smaller and smaller, i believe it is too late for nikon, time will tell.
  9. nikon wont have time to get it right, after being dormant for decades , camera market is moving fast, today's tiny market is too small now to have so many different camera makers
  10. z6 was a nice camera, too bad nikon did not grab the opportunity to be the first hybrid FF camera with raw video, they now tiptoe with a paid raw upgrade with return to service center instead of going full speed ahead, window of opportunity is closing, they wont have a second chance now that the camera market is quickly shrinking. this is the nail in the coffin, nikon is so dead. i believe sony and canon will be the only 2 survivors in the hybrid camera market (unfortunately for us consumers, as less competition means slower innovation and higher prices)
  11. s35 and 6k are nice to have but what we wanted was bigger internal battery and internal ssd slot (m. 2 or sata) ! both would have cost nothing extra but made it a one piece camera instead of a rigged hell
  12. they hit no wall, they are just without competition in the sensor business so they have no incentive to innovate, things will come from newcomers, samsung was a good contender but they drop the ball
  13. what i don't get from nikon perspective is why raw over hdmi and not raw over usb3 it is computationally the same cost to serialize uncompressed raw over usb vs hdmi hack but you only need a $100 external ssd instead of a $700 external recorder. and by serialized raw i mean just that and no cinemadng codec, any software intern will make you a premiere plugin in 1 month that will import serial raw data.
  14. your hypothesis of sony putting pressure on nikon though sensor delivery to cancel raw video could makes sense. with the shrinkage of the camera market due to cameraphones that are good enough for 99% of the population needs, there will not be enough room for all existing camera makers, nikon not being in the strongest position they should quickly deliver raw video if they want a chance to survive, same goes for fuji. by the way, now that bmpcc4k you can buy today won't let you downgrade the firmware to get back cinemadng raw, what is the first price for a cinema camera that records real 4k raw (by real raw i mean uncompressed or lossless compressed raw) ? is it the canon c200+Atomos Shogun Flame for $5.1k ?
  15. "I doubt Cinema DNG by itself was the legal issue, but maybe the combination of Cinema DNG technology and the camera processing for it infringed one of RED’s patents" since then blackmagic also updated the ursa mini g2 firmware and cinema dng was not removed in the g2 so this legal issue seems to be pure BS. they most likely removed if from the cheap bmpcc4k either to harmonize their cinema camera line in terms of specs/price ratio or they want to push usage of BRAW over cinema dng. why can't they just give the real explanation so we can have an idea of their strategy and make informed choices in term of what software to learn or what camera to buy.
  16. snapdragon 855 does not support 8k video recording so is there a external video chip that records 8k video such as ambarella h3 ? https://www.ambarella.com/news/104/122/Ambarella-Introduces-8K-Ultra-HD-SoCs-for-Virtual-Reality-and-Drone-Cameras you mean it is the smartphone lenses that does not resolve enough details or you mean it is the jpeg quality that compresses the 48mpix image too much and removes details ?
  17. here a 3 of my 2 cents thoughts on the matter 1/nikon and fuji are the only two existing camera makers that can give us best uncrippled video because they are late to the game on the video side of the hybrid cameras market and have no cinema camera line to protect. blackmagic has already strated crippling their bmpcc4k by replacing the lossless cinemadng with a lossy braw that is inferior in quality in firmware 6.2 (they have higher prices cameras that still offers lossless cinema dng raw. it reminds me of GM that made an electric car in the 90s that threatened their ICE cars and then pulled back, look at the documentary it is interesting : https://www.imdb.com/title/tt0489037/videoplayer/vi2147287321 ), canon will never deliver raw on eosR it does not make any sense (or very crippled raw in order to not compete with their cinema camera line). 2/ one interesting thing to think about is that for photo there is no lossy raw, only lossless raw, i guess it is due to raw file size that is manageable for photo but not for video - when storage media price will go down in price and reach the 300mB/s write speed required for 4k 12 bit raw 24fps all these lossy video raw will go away, there will be h265 and lossless raw like there is only jpeg and lossless raw for photos. (we already have 1tb m2 ssd that writes at 500mB/s for around $100 today so it will just take a camera maker bold enough to add a m2 slot in their camera). 3/ the idea of lossy raw being a editing friendly video format that plays along well with your PC does not make sense because we will soon have video editing software that will automatically and transparently work with proxy video format under the hood, it is not available yet in video editing software because it need some extra code (i worked at adobe and looked at premiere code paths and i can tell you it is complex) but it will soon be as we are getting close to 6k and 8k raw, they will be forced to do the automatic optimized proxy video in order to be able to simplify the workflow and edit in real time in the UI on existing PC.
  18. the E2 FF is 6K, not sure they can do 120 fps at 6k but i agree it will certainly have faster slomo than nikon z6, good point, i usually forget slomo as image quality always suffers
  19. isn't there a 90% chance of having a sony FF sensor in both zcam e2 and nikon z6 ? if it is raw (real raw i mean, uncompressed or lossless compressed data) then DR and image should be exactly the same no ?
  20. what is so exciting about a FF z2 for $5k, if nikon z6 can deliver its promise of a uncrippled prores raw via ninja V then for $2900 you get FF raw video + proper monitor with tool to expose and focus + a FF compact still camera when you just want to take a few stills travelling light
  21. it will be lossy raw only ,720p cropped , 8 bit raw. and if you put a ef-s lens then it will be limited to 5 minutes max recording time and no audio (there will be a paying firmware upgrade next june to get the audio back, it will be called "magic candle" )
  22. what i don't get is that for such high priced camera as panasonic s1 why don't they offer uncompressed raw on usb 3.0 that has enough bandwidth for 4k raw in 14 bits, is it only to protect their more expensive pro video camera linup ? adding a hardware usb 3.0 path for uncompressed data out of the sensor is obviously not as expensive as putting a 10 bit h265 chip in camera plus the extra costs of upgraded thermal design and bigger battery to handle h265 compression+in camera fast sd-card write.
  23. "the upcoming A7S III is said to be using H.265 compression in their RAW codec which is an interesting hybrid of the two" it is a clever compromise and i know sony marketing team will be happy to label this "raw" but can we (the users) please stop calling "raw" these hybrid lossy codecs that have file size close to distribution codecs but has some more flexibility for better editing in post. the purpose of real raw (as defined by unprocessed data coming out of the sensor) is : 1/ to postpone all processing in post so it can be computed with more precise/sophisticated algorithms on a computer that can compute in non-real time rather than in-camera hardware that must do limited computations in real time due to restrictions on cost, size, power consumption and thermal constraints 2/ achieve higher raw lossless compression ratios for archiving as very complex/slow lossless compression algorithms can be used 3/ offer paths for image quality improvement and reduce raw lossless archive files when better algorithms comes out in the future
  24. this 1:58 slimraw compression result is lossless and the original was lossless cinemadng, correct ?
  25. sorry i am not a photographer i am a computer scientist, my job is to write algorithms were "1" are always visually 1 and "0" are always visually 0 no matter the angle you look at it
