  1. What I'm talking about is very clear and there is an expression for that in english language: Horses for courses. Just because two different devices do a similar work in some situations doesn't mean the CPU inside device A is suitable for the device B. GoPro isn't a Japanese conservative company, and yet they didn't use Snapdragon. Nobody said smaller node is bad! Points are: 1. Snapdragon, fabbed 12nm or 3nm, has an architecture designed to do a lot of things that are not related to professional dedicated camera, like gaming, playing music, video editing, web browsing, online money transfer, controlling diverse set of peripherals. Look at the M4. Nearly a quarter of the chip is occupied by the GPU: Ray tracing while you half press the shutter, huh? See those big rectangles at the left? Those massive CPU cores are there to run Genshin Impact, not calculating Zone Exposure. 2. While smaller node for dedicated camera chip is always good news, the big portion of the heat is generated by moving electrons from point A to point B (Sensor to RAM, RAM to CPU, CPU to CFe card). So as long as resolution/frame rate war continues, we'll have heat issue no matter what. So a slim active cooling system should have higher priority than an expensive jump to smaller node.
  2. With that logic Ericsson should use Snapdragon for its 5g infrastructure products, because its cheaper! Not yet. Sensor output is 10 bit. ADC is 10 bit. They put 10 bit data in a 12 bit file. 5W is 5W, whether you're able to cool it down or not doesn't change the fact that its not insignificant. Another issue is movement of the data. 6k60 raw is about 14Gb/s. No matter how state of the art is your CPU, 14Gb/s is 14Gb/s. Its too much to not generate heat.
  3. The correct translation: "Smartphone makers overplayed their hand in image processing in such an aggressive approach that some of their users came to this conclusion that the only way to get better image is to have a camera with bigger sensor".
  4. Sorry, it has a lot of to do with the way the OS works. Its designed to handle a heavy and complicated OS system. The whole architecture is overkill for a dedicated camera in some areas, and underperforming in other areas. And remember all these 3nm ISPs are working with 10 bit images. Not 14 or 16 bit that your mirrorless chip is handling at fraction of a second. They don't design their own chips. They tell a ASICS/FPGA vendor what they need, and that vendor offer them one of their products. Nikon buys from Socionext. This giant company has TSMC as its 2nm partner. But doesn't make anything in its portfolio at cutting edge node. Because they don't need to, and will be expensive. And iPhone 15 pro overheats shooting 4k, remember?
  5. Excuse me, why we need Snapdragon for our mirrorless camera again? If you're suggesting it should have mini Instagram app built in, I should say that's a terrible idea brother. A dedicated camera is a professional tool. You can't tell the NFL players wait a moment guys, I need to reboot my camera! Maybe you're asking "why my camera can't automatically stitch my pano images together to give me a single file?". Well, if you want all things "auto" why you use a dedicated camera in the first place? That tool is called professional camera because its supposed to give you control; and now you want less control? The funny thing is that Apple is decreasing the auto things, like adding log profile, and increasing controls, like the new shutter button. The funnier thing is younger generation don't ask for a iOS camera with a full frame sensor, they like the Nikon Zf/Fuji X100 ideas, cause these cameras have more direct controls on them (a retro styled camera is slower than the modern ones, but thats another matter). What we need is better implementation of wireless connections, between the professional tool and the consumer devices. I can't use my Bluetooth headphone as monitor headphone of my camera, as one example (BT6.0 will solve the latency problem. Lets see what they do). Things like this move very slowly. USB4 can deliver power and uncompressed 8k60 data, but nobody dares to replace SDI with that.
  6. Please test the new Rec.709 LUT too. "The LUTs for N-Log, which were previously provided for each individual camera, have been consolidated into a single file and optimized for video production based on color science developed by RED (Red Digital Cinema, LLC). The Technical LUT converts the N-Log color space to the Rec.709 standard, making it suitable for general viewing."
  7. Isn't it easier with a boxy camera to rotate the body 90 degrees?
  8. 3:2 aspect ratio is now odd in the display industry. All they make is 16:9 or 18:9. So maybe there is just couple of low volume suppliers that still make this kind of display and they're not very flexible in changing size/resolution.
  9. Seems Canon use Clog for temperature too lol. 8k60p runs 6x times hotter than 8k30p, not 2x: 120 minutes vs. 20 minutes. Andrew talks about sensor fabs and cmos technology, but what about processor? Can't they order a more efficient one like everybody else do? I don't expect 3nm chip, but come on.. you're Canon, you have the cash, more than any other camera maker. Buy something new.
  10. Not very effective. The difference it makes for 8k60p is not dramatic. Its for people who shoot 4k interviews.
  11. I just didn't find "fine" mode for 4k60p 10bit.
  12. 8k raw bitrate for 30fps is 2600mb/s. Thats 4.6:1 compression ratio. For 8k60p you have to use "lightweight" raw, same 2600mb/s, and that equals to almost 9:1 compression ratio. 8k24p 10bit 4:2:2 "high" intra: 1920mb/s. Seems like there is no 8k60p 10bit recording. Also didn't find 4k60p "Fine", so its not from full sensor readout. The only "Fine" 4k60p is 8bit 4:2:0.
  13. Tests show that 6 stop is borderline unusable and thats 14 bit. Nraw is 12bit and will be one stop worse. So I would say 2 stop over and 5 stop under with NR.
  14. With this logic, which I'm not arguing against, AI would kill the smartphone market first. Why should I upgrade my $1000 phone when I can update my camera app for $1.9 per month?
  15. If all you need is 4k24p raw, the bitrate is only 340mbs
  16. A camera should be a tool for capturing the data with highest possible integrity, not a "machine artist". When you have the data with highest possible integrity, you have the choice to make it as trendy as it gets, or keep it as clinical as it is.
  17. If you want unlimited recording in any temp, and at this price point or even a bit higher, you have to give up something, either Full frame sensor (GH7) or EVF and higher than 4k resolution (FX3), or internal raw (S5ii). There is no conspiracy to not giving customers a perfect camera. The reality is that making everything right is becoming more and more expensive.
  18. No, its not stacked fast. Its just faster than non-stacked sensors.
  19. That line support came out of nowhere, and makes me think how this rumor/leak business works. Nobody cares about audio to the point that when they want to leak a feature, the audio related ones don't cross their mind.
  20. NRAW 60k60p indoor recording: 1 hour and 45 minutes https://m.youtube.com/watch?v=kTej8zJFCXY&t=1158s
  21. Lol maybe I'm wrong "The Nikon Z6 III is rumored to have a stacked sensor (or partially stacked?) from Sony. That same sensor is expected to be used in the upcoming Sony a7S IV, rumored to be announced later this year. I was told that Nikon got a special and exclusive contract with Sony and only Nikon and Sony will use this specific sensor. Nikon had to buy a lot of them in order for Sony to agree on exclusivity. This explains the rumored high price of the Z6 III."
  22. I still can't believe its stacked, even at higher price. We'll see.
