  1. Yeah, 3.76um that's right, had the old 24MP APS-C Pixel in mind, which was 3.91um. I suspected that the IMX455 would make it into either a new Nikon Z (or D850 successor), Pentax K1 or Sony A7RIV camera, but haven't heard any rumors about it. Z Cam E2 F8 is already introduced, that's interesting.
  2. I am not. If pixelsize is the same, bigger sensors have higher pixel amounts. with the 3.91 micron pixels there is the 26MP APS-C sensor, the 100MP 44x33mm medium format sensor and the 150MP bigger medium format sensor. A 60MP full frame sensor seems to be in the pipeline. And if you crop one of those sensors to the size of one other, it has exactly the same pixel count. And yes, crop factor as linear factor is the square root of the area. Anyway, no matter how you calculate it (horrizontal pixel amount, area, pixel size) you end up with a crop factor that is close to 3x. (3x means 9 times the area). But let's do the math. The sensor is 44x33mm. In 16:9 that's 44x25.75mm On that surface there are 11648x6552 pixels out of which 2/3 are actively read out, ending up at 50.9MP (but that number doesn't matter, since we are only interested in the area). So we are downscaling from 76.3MP and 1133mm^2 to whatever size can hold 3840x2160pixels. (8.3MP). That's easy, 76.3/8.3=9.2x So the area from a 4K crop would be 1/9 of the used area. As I said crop factor is the root of the area so we end up at ~3, again, the value I guessed. Looking at wikipedias list of sensor sizes, we can find two listings for 2.4x crop. Why 2.4x? Because the GFX already has a crop of 0.78x and thus we have to multiply. (the crop is smaller in 16:9 aspect ratio, but let's neglect that). One of those is the 1.1" Sony IMX253 Sensor.
  3. I think the GFX100 sensor isn't really designed to handle video as it's highest priority (if it was, it probably wouldn't be 100MP), but stills. And still it seems it's a great option for those looking to go beyond full frame and try something special. That the GFX100 does 10bit internal at bitrates of up to 400Mbit puts it up there with some of the best full frame cameras, while reading over 50MP. That's some crazy stuff. 50MP at 30 frames a second, that's 1500MP read and processed every second (adc drop precision to do it and that decreases processing power needed, it's still immense though.)
  4. no, at APS-C/S35 size it's still an 26MP (3:2 format) X-T3 sensor. To get a 1:1 4K pixel readout it needs to crop past micro four thirds to something close to 1.1" sensor. That's a crop factor of over 3. Would be great for wide angle shots That's probably what canon would do 😄
  5. that's what people repeat over and over again. They claim that the very old lcd panel was the only way to get 120fps. To be honest, I couldn't see the difference between 120p and 120i in different cameras. What I could see was that it wasn't resolving anywhere close to the competition, the contrast wasn't great and so on. But that's not the main critic I have about the viewfinder. It's the blackout that's still there when shoot fast pace. And that's where other manufacturers are infront it's not. It's good. It's a 3 year old 20MP FSI 12bit mFT sensor. Again, this is where competition is running away it's good. But again, competition is overall better and is doing it was less than half the price! I wouldn't criticize it, if the camera was <1000€ or even 1500€ due to the formfactor, but at 3000€ it should be best in class. It's not. hopefully. As I said, I think that the E-M1x should either be better at many small things or cost a lot less.
  6. Hopefully a lot more. While it‘s probably one of the best cameras you can get ergonomically and offers some unique feature, some main point such as image quality, autofocus or viewfinder performance have fallen behinde competition. Especially if you consider the price I guess 2019 won‘t be Olympus‘ year of the E-M1x, but the E-M5III
  7. The hasselblad is great looking and well made. it‘s small while not light making it dense. This makes it feels well made, just like a Leica M. Are all other cameras toys? Maybe. But then again, there are multiple orders of magnitute of pro photographers using those toy sony, fuji, canon, nikon ... cameras, then there are hasselblad x1d users. and tbh, many would choose features and handling over that feeling. when it comes to image quality I would argue, that capture one is superior to phocus, thus the fujis are at least on par. Being polemical as well I‘d say the toy camera is the one, that rich dentists and lawers buy as a status symbol
  8. So this is, what the X1D gen I should have been. I expected something else
  9. You judge the performance of all lenses due to a single image? If that were the case, the new S lenses are not good enough fro 47MP or even 24MP, since it's easy to find unsharp examples. Same with Sony GM glas or the new Canon Rf glas. There is still no RAW support, just jpgs out of camera and all of that with a machine, many are not accustomed to. I remember when the D800 came to market and people needed to learn how to use it first. The GFX lenses seem to be some of the sharpest lenses out there. Highly unlikely that they will produce new versions of their lenses. There are a few high res jpg to download at jonas rasks review: https://jonasraskphotography.com/2019/05/23/at-the-brink-of-tomorrow-the-fujifilm-gfx100-first-look-preview/ if I zoom into pictures like DSCF0411 and look at the single pores, that's just breathtaking. I don't see anything missing there. But of course not all images are as sharp as that one, but I wouldn't blame the lenses
  10. first tests claim there is no 30 minute recording limit and that the dual batteries should last around 3 hours of 4K recording. What a beast! Would have been interesting for them to put in some crop options too
  11. Let‘s hope for that. And let‘s hope that goes for price too. Competition is good for the consumer!
  12. i know. But what technology does DJI bring into this relationship? They don't have IBIS, no experience with phase detection. They may contribute to save a few bucks with their processors or a few parts. But all in all I think Hasselblads main interest was to get a name they can print onto their drones and sell at a premium. I don't see much, they can add to the way Hasselblad work at the moment. I may be wrong and we see a X1D II made in China soon?
  13. I haven't followed what Hasselblad does as closely, is there a X2D/X1D 100c announcement around the corner? Thinking about hardware, I don't see Hasselblad compete. I don't think they will manage to get their own IBIS (but maybe they will licence it from Sony or Nikon since they already went with Nikons lighting hotshoe) or get anywere close in focus performance. But I expect the Hasselblad to be as well built as the X1D, one of the nicest cameras besides a Leica M one can probably buy. If I had anything to say at Fujifilm, I'd put in an anamorphic mode into that beast. 😄
  14. the app is great. as long as you don‘t need to use it. it drops resolution to 720p or 1080p depending on your camera and bitrate as well. It deactivates certain settings as well. It‘s fine for photography or updates but it sucks for video
  15. I love how he claims it's the iPads and everything else fault. So, if you can't watch it on an iPad, with factory calibrated screen, covering DCI P3, working with variable frame rate to match the content, offering over 500 nit brightness and extremely good contrast what should we get? 4000$ HDR Oled Screens? In the end it was just too dark and HBO made it even worse with their crappy compression. Get your content delivery sorted and then start blaming customers!
  16. it doesn't make it parfocal, since that is, by definition, that the focus doesn't change when you zoom. But the focus does change and it is corrected by the focus. Sony got an interesting solution with the 18-110mm f/4.0 too, where the focus element is moved to correct. The problem with such electronic solutions is, that fast zoom movements can be too fast to correct and that you can't use those lenses on another non supported mount via adapter
  17. androidlad already explained it: it's exposed at ISO160 (or higher ISO) for the highlights and shadows and midtones are pushed. And this is reflected with a higher ISO value. It's actually one of the easier, very reproducible dynamic range extension functions.
  18. I have photographed many weddings and the 35mm f/1.4 has been there since the Fuji beginnings. The only one who would notice the focusing sound is the photographer himself. If my second shooter used the lens, I never picked up on any sound. For video though, external sound recording is absolutely necessary
  19. if you use the internal mic to record then yes. But if you do, you probably shouldn't shoot weddings 😄 As soon as you move the mic away, it won't pick up the sound.
