  1. 1. Because it says Toshiba on the chip There are teardowns of the camera on the web that show, that it's a toshiba sensor. But it doesn't really matter who makes it, the sensor is great! 2. The problem is, that the camerastore guys know nearly as little as Jon Snow does I like them for entertainment, but they aren't really very good with physics or comparison ^^ Thing is: as I said, in good light there won't be huge differences in noise performance. What we see there is the noise from the light itself and there is just no way around it. The differences (in noise) due to the technology can be found in darker regions, when pushing files or at very high ISOs. Many manufacturers have tried to fool customers into thinking, that the new sensor is a lot better. For example the A7R II need about 1/3 EV more light for the same brightness than the mk1 version. Of course one could argue, that Fuji always used a different ISO standard, but the X-Pro2 at least gives the same brightness as the last gen (X-T10, X-E2...) Olympus went a little bit further: the OMD EM10 mk2 seems to overstate the exposure time. That's very dangerous! Fuji improved their jpg engine (and has a more powerful processor) and the resulting jpgs are a lot better, than the sensor itself. Anyway, here is the DPReview comparison. Personally I think the X-Pro2 looks very good. Even better than the others. Download the RAWs and compare for yourself. Even when you remove the color noise from the D7200, the X-Pro2 (for me) has an advantage in noise, detail and color. The last point is very interesting: while in the ISOless comparison the D7200 looks much better, when you push the files (or just recover the shadows), I think the X-Pro2 is cleaner. Furthermore the D7200 introduces some color shift. This isn't to make the X-Pro2 the best camera or trash talk all others. The D7200 is a good DSLR and the price is awesome. The A7R II still has a better sensor than the X-Pro2. But it looks like we now have the best APS-C sensor on the market as well as the best APS-C lenses in terms of lens speed.
  2. There is no Sony Sensor in the D7200. The problem with those home made tests is, that they aren't scientific at all. With good light, there is little difference in noise performance (you could throw in a X-T1 or even a X100 and probably won't see big differences). The difference become visible, when you use the camera in low light (and with longer exposure times). And of course there are things you can to do a basic sensor to improve it's performance. Efficient microlenses, cfa, read out. Even cooling when it comes to longer exposures. And that's not all by far. And that's just the technical side. There is the aestetical side too. How much detail is there at higher ISOs? How does the dynamic do? Are there banding or color shifts when pushing the file/shadows? And finally: how does the noise look? Personally I think that the noise from the random Fuji X-Trans has a very film like look to it
  3. Fuji often uses focal length instead of field of view. (physically not correct but better for comparison)
  4. This is hard to say, because your definition of a generation is different to the yours. This sensor (X-Pro2/A6300) is probably around the 5th 24MP sensor. But for Sony it's a new generation once they improve on the manufacturing process. If Aluminum 180nm is Exmor gen 1, then the move to copper (90nm) is gen 2. I think we didn't see this one on the big sensors, but moved directly to gen 3: 65nm copper. The goal is to reduce the wiring depth, get better fill factor and allow for greater angles of incidence. The next generations/idea would be, to increase dynamic range and saturation (as well as sensitivity) by increasing the pixel full well capacity. Since most of this is happening in the >800nm wavelength region, it gets the shortcut NIR, for near infrared. How much real life impact this would/could make, I can't tell Next gen is BSI. and then combine BSI with NIR and/or going into 3D - stacked Sensors. I think you can look those things up too somewhere.
  5. Told you it wasn't the IMX 271 No. Sony (devices/semiconductor solutions) builds this to customer specs. The shielding isn't happening on a deep sensor level, so like the CFA or black light shielding this depends on the customer. (The mistake many make is to think of sony as a whole. It's Sony imaging that builds cameras and that is only a customer to Sony devices/ss) If we take away the 3-400$ premium for the hybrid viewfinder there isn't much left. Fuji also offers many other things that many overlook. Just to name two: 1. they integrate UHS-II. Not only the specification but this is on hardware level and this is why Fuji can really achieve 300MB/s while others (A7!!!!) limit it to 60-100MB/s 2. the screen. The X-Pro1 had an RGBW panel higher visibility in sunny situations and the X-Pro2 goes even further. Those are just two selected differences. There are much more. As a european customer support and warranty come to mind.
  6. Yes. It means that every single pixel is read out (electronically) at the same time. So no rolling shutter and other shutter problems.
  7. Not only that. Fast lenses would benefit from it too. (And Fuji has a lot of those) I don't think we will see this tech before 2018-2020.
  8. I don't think it would be outrageously expensive. The nice thing about this sensor is, that you don't even need BSI infastructre since you "only" put the organic layer on a FSI sensor. The thing I like most about this sensor is the new microlens design that allows for 60 degree angle of incidence.
  9. I think you are talking about two different things. Canons ISPs have had ARM based CPUs for decades now. (afaik they were based on TI OMAPs) And since they weren't really made for their highest end cameras, they literally put two chips on the PCB. To be honest, I haven't really done a Fuji tear down (why would I ^^), but I think they have put two cores in their processors (so one chip, not two) for quite some time now. The big thing is, that EXR III moved to Cortex A7 (dual!) cores and also increased the clock. And looking at the pure specs of the EXR III I would say it is a bit over designed for the X-Pro2. The processor most certainly is no bottleneck when talking about a bigger camera. So one could say, that Canon is building their processors for the entry/mid level and if need be, they put it into the pro bodies. Twice. Fuji on the other hand has a really modern, very powerful high end processor, which it puts into their cameras (I think it will stay high end exclusive for some time and we will also see EXR II and X-Trans II not go away for months/years)
  10. Sensor could do 5k 30p. But I don't really see a point in it (but that could be some firmware update ) 4k 60p is different. With fuji it isn't really the speed that is the problem, but that the X-Trans is an irregular pattern that is harder to demosaic (you need more processing power). So a slower video but with full sensor read out and downsampling helps more - the video quality gets much better The sensor readout is much faster than what you quoted (what this means for the sensor you can think for yourself ) The problem with EVF cameras isn't the maximum fps (and don't worry about the processor ), the problem is the viewfinder blackout. 10-12fps gives you blackout. The readout/blackout time should work out to something around 6fps. (Personally the 8fps on the X-T1 are more than enough for me, the blackout is the problem. 6-8fps without blackout are more than enough) So to sum it up, Fuji can do 4k. The sensor could also do 5k. And weathersealing is nice. So are two SD slots. The problem is: all those things don't really play nice together. Fast sensor readout (especially in video) with the huge processing power need, you get a lot of heat. Putting more stuff into a small body (2 SD card slots) and sealing it only makes this worse. So I wouldn't expect 5k recording for 30 minutes continuous (I guess you get what I am suggesting)
  11. That's a hard decision. C1 is more powerful than LR, but still, there are somethings I do in Photoshop, that are just not possible in C1 (or LR). But I am thinking about Affinity Photo (+C1 and going Adobe free).
  12. 400*2*1,5=1200mm FOV equivalent. And that on a 24MP sensor. Crop to 16MP gets us to nearly 1500mm equivalent :-D
  13. Watch some webinars, take your time and force yourself to use it (and not only for some light exposure compensation and white balance work, but for nearly everything. And after a few weeks (a few thousand pictures) it will have grown on you. And you will think back at the times you were using Lightroom and will ask your self: how was I able to work with such a limited software?!
  14. Actually the X-T1 can handle HSS, as shown by the Nissin i40 So the TTL protocol is also capable of HSS (it knows how to sync the flash to the first curtain shutter). If the camera is HSS capable, activating it can be done with a firmware update (I'd say FW 5 for the T1 is very likely)
  15. That really sounds awesome. And according to your review, we won't see any shutter shock like on the A7R or EM5?
  16. Furthermore on dpreview, Fuji said similar things (and there we have the SNR too): http://1.static.img-dpreview.com/files/p/E~TS590x423~articles/2176896871/DSCF9146-anniversaryeventslideshow.jpeg The claimed improvement of 7.6db is over a stop of improvement! If this turns out true, I stand corrected. I didn't think we would see more than 1/3 of a stop improvement. (Nikon claims similar things with the D500. It looks like those new Sony Exmor sensor really are outstanding). Anyway: we have to wait to see some RAWs (and measurements) to get "final results". But until then I'd say: this is one hell of a camera (and an awesome sensor and processor)
  17. The thing is: a bit over a year ago Sigma said: That's something many know - it is very hard to design good lenses (especially at the edges) for the E-Mount. The new sensor of the A7R II helps. I guess more cameras (A7 series) will move to BSI due to this. Of course Sigma will someday produce mirrorless lenses. But I think they are waiting for either Canon or Nikon to enter the market. Why? Because if they designed their lenses for E-Mount and one of those two would release their mirrorless system with longer flange distance it would be difficult to get the lenses working (or Sigma would need to design the lenses for a longer flange distance anyway, making the lenses unnecessarily big). About the X Processor Pro: I guess Fuji will use this for moths/years to come in many of their cameras. And those will concentrate on different things (one being 4k). And it handles all of that.
  18. http://www.fuji-x-forum.com/topic/2043-live-from-tokyo/?p=18542 If one takes low pass filter and different lenses into account, this of course can be true, but is no in general (It was the same with the last gen, which could achieve similar results as an 22MP Canon 5D3) Of course this is mostly marketing. But it also shows how confident Fuji is in their lens lineup.
  19. in one of the reviews there were Full Well Capacity (18000e) and Read Noise (1e). With this, you can calculate the per pixel dynamic range the manufacturer states. (I'd have to look for it - but it was one of those listed on the FR page) Of course, real life dynamic range will be different. But over 14stops is really impressive.
  20. copper, no BSI. Sensor Dynamic Range per pixel: over 14 stops (but those are just the numbers, real life performance will be interesting) Anyway it seems, we got a totally new sensor, no one used bevor. And it seems that it is outstanding too.
  21. I guess it will be like this: you can select either 7x11 or 13x21 AF Points. and then there are either 7x7 or 13x13 PDAF points (total of 169)
  22. btw. they are back online (check the comments on FR there is a google drive link. Files are legit)
  23. Most interestingly: the guy put on the 90mm. And then they show an OVF screen with no lens showing up. It's all fake!!!! XD
  24. Better not watch the video - it doesn't do justice to the camera, which will probably be outstanding @Maurice: thanks for looking for those pictures!
