  • Thanks for sharing your experiences with us, they seem to have lifted the quality of the thread to everyone´s advantage. For many users some of the editing techniques may be a little too ...
  • Thanks for your reply. This is exactly what I´m getting at, 4K is interesting and sometimes worthwhile, but it does alter how you actually film. How large a screen do you watch it on?
  • The crucial point is that at a certain distance from the 2 equally sized screens you mention, one 2K and the other 4K, the latter will show more detail which is not visible at greater distances. ...
  • It is clearly not the FOV of optical instruments the discussion is about, but the FOV of humans who are undeniably the ones who are watching the screens in question as discussed by the ITU in ...
  • Would be more interesting to hear your views on my initial Query. For definition of FOV see below International Telecommunication Union: the field of view of HDTV is only 30 arc-degrees. Our ...
  • I mainly mean how you compose your pictures. A little has already been dealt with in the thread regarding 4K IS. 4K does open up for wider shots with less camera movements since the improved ...
  • Created discussions How do you film in 4K?
    I don´t mean how you set up the camera, but how you actually carry out your filming. Do you use more wide angle shots and keep the camera more still, letting the objects move more within the  view ...
  • One of my doubts regarding 4K is the absence of 50p so far (see the dicussion thread regarding reasons for this). I think movements in videos are usually captured better at faster shutter speeds, ...
  • It is very much relevant to this camera, since the RX100 M4 offers 4 times (twice the horizontal)   resolution compared with the RX 100M3, it is indeed the whole point of 4K. If "the piece of ...
  • What sustained write time are we talking about? Going from 25p to 50p in 2K does not have such dramatic effects on the speed required although I´m aware that the computational requirements are ...
  • In reply to ncskany: The concept of FOV when watching a screen (or any other object for that matter) is very simple, it is the ratio between width of the screen (or object) and the distance from ...
  • Stephen McDonald : Having re-read your comment above I see you must mean the widest angle the camera is capable of rather than the viewer´s perceptual FOV while watching videos. In the context of ...
  • Surely the Alpha 7R II would be first in line for 4K 50p/60p, but as it is hardly out yet it seems a bit early.
  • The 5mins limit does not apply to the RX10 M2 or the Alpha 7R II, at least the latter should offer 4K 50p one would have thought. Not sure if I would always trade 2K 50p for 4K 25p but there again ...
  • I agree about Sony not always being completely accurate. But if you film in 4K in good light (quick shutter speeds) you should (on a good 4K screen) be able to enjoy very good extracted stills. If ...
  • Stephen McDonald: I couldn´t quite follow your ideas of 4K and FOV which also have direct bearing the effects of quick panning. As I stated earlier 30 degrees of FOV appears to be ideal for 2K ...
  • The FOV (how many degrees the image occupies of your vision) you obviously decide on yourself, I took for granted that anyone interested in 4K would understand that the whole idea of the ...
  • The large FOV which is one strength of 4K makes fast panning quite unwatchable! Rolling shutter phenomena are largely the result of painfully fast panning these days, not inadequate cameras. With ...
  • Technically quite impressive, but in reality of rather limited use. Who wants to watch these sleep inducing clips for any length of time? There again for time and motion studies they might prove ...
  • A SanDisk Extreme PRO UHS-II card would possibly write up to 250Mb/s but no Cybershot camera copes with this speed as far as I understand. I still think heat  would be an issue for these very ...
