  1. Just saw the last blog post from @Andrew Reid - NOW I'm curious. 🙂
  2. The plot thickens. Best case: there are more than one temperature probe; the API is reading the CPU temp and the EXIF data is internal temp. Hence, you have an failed documented API. Worst case: a class action lawsuit ready to win.
  3. Towerjazz used a Nikon Z image in one of their reports, leading to believe that the Z6 or the Z7 have a Towerjazz sensor. If this is the case, could be a good alternative. But very interesting report about the security market size. Yeah, that is what could bring a new MFT sensor.
  4. Just to correct (a little) my previous assumptions - I had only saw the pictures of the dissassembly, not the video. Now I saw the video, and there is a metal part between the smaller PCB board and the mainboard, where the thermal pads makes contact. If this metal part had a heatpipe to draw the heat away, the problem could be minimized. IF the problem is really heat...
  5. Yeap, exactly my point. As I said, I have some electronics background, and a 2nd year student would never make that mistake. CPU and memory with a thermal pad to conduct the heat...to another board? And when you have a big heat spreader just behind the main board, but put the chips in the other side? It is on purpose, or they have the dumbest engineers in the world.
  6. The "fun" part is that THIS heat pipe could be implemented in the R5 - I has never saw the picture above, never would thought that a heatpipe this small could work. A similar approach could work in the R5 - a thin metallic shield in contact with the chips with thermal pads, and this heatpipe conducting the heat to the bottom plate (it just have to avoid the connector for the board that sits above the mainboard). Than you make the bottom plate with two "floors" (like the heat spreader on the Sigma FP1), with a gap in the middle to help in ventilation and to prevent the bottom to be very hot to touch. Still in the engineering regard...the drawing of the internal heat spreader of the A7SIII looks VERY similar to the on in the R5. Maybe it is a common way to make cameras?
  7. Yeah, everything in this case is VERY strange. I will go back to the pics of the camera internals (I was an electronic technician ages ago, but our @BTM_Pix could give a much more helpful opinion): or these pics are false, or I missed something, or Canon engineers made mistakes that a newbie electronic student would not do. First: the two thermal pads, besides not covering the CPU, are completely useless. According to the pics, above the mainboard there is another smaller board; hence the thermal pads did not conduct the heat to a spreader, but to ANOTHER BOARD? Second: looks like that a big metal spreader exists BEHIND the main board, with a single pad. Canon is trying to dissipate the heat this way? It would be the most inneficient method to do it. If they wanted that structure (the 9th picture in the article) to serve as a heatsink, the CPU and the memory chips should be mounted in the other side of the mainboard. It is utterly stupid. The hipotesis that the pictures could have something wrong is because of the first pic, that shows the back of the back panel of the camera. The gray part looks like magnesium, and there are some "squares" there that looks like to fit some chips on the board, but it is completely different from the smaller board that goes over the mainboard. The rest seems legit - but completely absurd engineering. To solve this, using that big metal part as a heat spreader, they should kind of flip the board layout, but mantaining the actual connectors in each side. This means a completely new desgined mainboard - and it is not the best solution, that metal structure is closer to the sensor, and the heat could bring noise to the sensor. Don't see to much room for a heatpipe to conduct the heat to the bottom of the camera (the best solution on my view). If this pictures are real, it is one of the must dumb designs ever.
  8. "Não tem como" buy a Red camera in Brazil, with the import taxes and general vendors greed. A Komodo will probably cost more than a full equipped SUV here.
  9. Priest: "If any of you has a reason why these two should not be married, speak now or forever hold your peace." Film maker: "WAIT THIS PEACE OF SHIT IS OVERHEATING!" Bride to groom: "See? I said to you to use a lighter fabric in your clothes"
  10. Or could keep some relation with latest EOS developments and rename to OvenHD.
  11. In this case, not. Looks like that they were targeted by Maze, a ransomware group, that already hacked LG and Xerox. Garmin was targeted by another group these days and reportedely paid some millions to recover their data. It's a professional job.
  12. Thanks for the offer @BTM_Pix, but have all of them here with me, hehehe - just don't have the time / skill to do a proper test (Covid + tons of work + baby in the house). Would be for stills, for instance - just to know the better one to bring in (future) trips.
  13. Test that I would like to see and never found: a comparison between the Panasonic cheap kit zooms. The 12-32 pancake, the 14-42 II (the smaller one, not the first version that came in the GH2 times, which is garbage) and the 12-60 (not the Panaleica). The sites that tested the 3 always used distinct methods / cameras.
  14. SInce I'm considering a Fuji future, I was just asking you about it...but if you enable silent mode, you can't use any dials to change the settings, no? Ok, aperture is usually on the lens, but you can assing ISO to the front or back dial? And how you enagage it, could map a button to press?
  15. Have it, love it. Only problem - not always trivial to use a 150mm eq lens anywhere. 🙂 The 3 MFT lenses that, when I browse through my photos and find one that gets my attention, 90% of time was taken with the Oly 75mm 1.8, Oly 54mm 1.8 or the Panasonic 20mm 1.7.
  16. 2020, crazy year. Where the discussion about top video mirrorless camera moving from "overrated" to "overheated".
  17. Back to the camera: the E-M10 MK IV was released - so undewhelmed that maybe it do not justifies a separate topic. Get the E-M10 MK III, put the 20mp sensor, a slightly better grip, a flip down screen (useless when filming handheld with a small tripod), slight better AF and...that is.
  18. I doubt it. Sony really does not care for its APS-C line. They are iterating it A6000 body forever, reusing the sensor with horrendous rolling shutter, and never responding to Fuji dominance on the format. It is only a cheaper gateway to E-mount, just there hoping that people jumps after to FF.
  19. Just commented in the Dpreview post exactly what you've said, @Andrew Reid - the R5 was and is marketed as a professional video tool. But I guess that they only could do a recall if the overheating happens constantly in stills modes too. In the photo forums that I've looked, they are giving a damn about video overheating. And stills shooters still (no pun intended) makes the most of the sales.
  20. I think that our house resident genius @BTM_Pix never worked with the Olympus wifi protocols, but I think that he can bring some guidance. Since @leslie is working with Adruino stuff, probably have some programming knowledge to discover a way.
  21. How these phones are working with other camera / movie apps? And the stills raw modes? Would love to see how they work using Filmic Pro.
  22. Indeed. Since I'm probably the sole m4/3 user and a complete amateur, each purchase decision is for my pleasure only - no chance to get the value back with gigs. Don't have interest in full frame cameras, since (as I'm not a professional) I value much more lightness and compactness than pure image quality. Besides low light performance (kind of important to me since I like to do video / stills in concerts - had some of my stills published in some Instagram's bands) and lack of good video AF (less with the PDAF's Olympus), m4/3 have all the quality that I need. But in my view, things are not rosy in the m4/3 camp. Don't see JIP making Olympus relevant again. And each Panasonic's m4/3 offering since the GH5/GH5s/G9 are increasingly disastrous. And no rumours, no new roadmaps, nothing is coming out. Right now, after a boatload of bodies that I've got, I have a E-M10 MK III and a GX9 (except for the 4k crop, is it better than I've expected). Would like to have a E-M1 MK II or III or the E-M5 MK III because PDAF (and which is probably one of the best patents - only could be a strong patent to not be copied - that thay have, that are their long exposure modes with instant preview), but...now, I do not see a future, at least with bigger companies (still think, as @sanveer, that m4/3 stillhave a relevant role in niche video). I'll be offloading all the lenses that I have few use (even maybe my preferred one, the amazing Oly 75mm 1.8), and I see two paths for me: - Move to Fuji, since is the closer to size / weight to m4/3 - albeit my few experiences with Fuji were very strange, most worst results than m4/3 but when it gets better, were MUCH better; - Keep only a minimal m4/3 kit, wait for both Olympus and Panasonic killing their m4/3 lines, and grab bodies / lenses new or slightly used for cheap and use it until everything dies, than choose with the surviving options.
  23. In front is a tally light, no ToF sensor. S1H have the same arrangement, only vertical.
  24. But the rest is EXACTLY the A7R IV - they switched positions between C1 and Rec, and...that it is.
  25. Is his case probably it even overheated sooner, due to the power line to the lens overheating too, trying to keep that bush in his chin in focus at f/1.2.
