    Are these still for sale?

    These are great - have watched them so many times! Actually just bought the Hypergonar Hi-Fi 2 today as well as the Rangefinder.

    It still seems you didn't shoot correctly with A7s and with that in mind it makes a lot of sense that you see a big difference between the two. You mention that you have used the 1Dc extensively but not the A7s an that alone, to me at least, makes your statements invalid. That its backed up by a pro working for Sony too is invalid unless you can present his findings. If you expose the A7s "correctly" (meaning not ETTR) you will get more noise because the sensor needs the extra 1 or 2 stops of light. The 1Dc on the other hand works best if you expose it "correctly" Even with this taken into consideration I still don't find it realistic that the 1Dc can be as sensitive. Unfortunately I don't have a 1Dc so I can test it for my self.

    I would love to see douglaurent compare the 1Dc to 35mm film. Lol. Btw, when is the next part of the review coming up?

    ​That is normally the case for bit depth and DR, but not as much for ISO - especially not with the codecs on the A7s and 1Dc. Even with a big difference between video and photo the relation between the two should still be roughly the same, right?

    ​Being a A7s owner I find it very difficult to recognise any of what you are writing. I don't have the Shogun yet but can't imagine it would affect the ISO performance. I know DxOMark are not always the best source of information for filmmakers but in regards to ISO I find their numbers very believable. As the 1Dc and 1Dx share the same sensor I have chosen to compare the A7s to that: A7s score: 3702 1Dx score: 2786 http://www.dxomark.com/Cameras/Compare/Side-by-side/Sony-A7S-versus-Canon-EOS-1Dx___949_753 ​I don't see how one of the biggest test labs could be more than a 1000 points off, but please let me know if I have missed anything.

    I'm really curios to see if the Shogun will record 120 fps 1080p Proves from the A7s!

    It seems that not many GH4 owners care that much for dynamic range but more about internal 4K. It doesn't surprise me that the GH4 is barely 11 stops, looking at all the GH4 stuff available it is very apparent that the dynamic range is around 11-12 stops.

    This is very interesting: http://***URL not allowed***/dynamic-range-sony-a7s-vs-arri-amira-canon-c300-5d-mark-iii-1dc-panasonic-gh4/ Brief summary: Amira: 14.5 A7s: 14.1 5D Mark III: 11.8 1DC: 11.7 C300: 11.4 GH4: 10.9

    Do you have a link?
  12. Birk Kromann
    Depends how good your colour grader is and how bad you light things.
  13. Birk Kromann
    I think people tend to forgot DR. We can discuss this forever, but resolution and but depth isn't everything. IMHO the most difficult thing to correct/change is DR ergo is should be the highest priority. To me that gives the nicest images and is why the A7s looks so much nicer. And that's talking from a professional point of view.
  14. Birk Kromann
    I think 14 vs 12 stops says it all. But again, people have different opinion as to what makes an image cinematic. And no Jason, I don't think you're missing anything. Although (how stupid it might be) this is a post with "who wins the 4K battle on paper" in the titel (and we are still commenting on it)

    After having seen the ISO comparison I've been wondering is it's fair to compare these to cameras? To me they are to very different cameras with very different specs aimed at different people. I would pick the A7s over the GH4 any time, but that's only because I value dynamic range, full frame sensor, ISO performance and quality photos higher than internal 4K, high bit rates, small sensor, M43 mount and small form factor. Other persons have their own features that makes either camera suited for them.

    In regards to price, this might shed some light on a possible price (although they state in the article that it might change before the actual release) http://www.sonyalpharumors.com/sony-a7-gets-a-provisory-price-in-uk-2500-pounds/ And a fun little ISO comparison: http://petapixel.com/2014/04/11/sony-releases-another-insane-a7s-low-light-demo-much-will-night-vision-cost/?utm_source=feedburner&utm_medium=feed&utm_campaign=Feed%3A+PetaPixel+%28PetaPixel%29

    See, that's what I'm unsure about. Would be great if anybody could confirm whether or not that would work.
  18. Birk Kromann
    Isn't it possible to convert the HDMI signal to SDI and use one of the existing 4K capable recorders or am I missing something here? To me 14 stops of dynamic range (yet to be confirmed by Sony) and amazingly good low light sensitivity is to me more important than internal 4K recording.
  19. Birk Kromann
    What was your workflow exactly?
  20. Birk Kromann
    Have you had any first hand experience with an Alexa?
  21. Birk Kromann
    And as always you're coming up with speculations and not actual facts. Nikon lobbying? Really?
  22. Birk Kromann
    Have you seen Dexter and Wilfred?
  23. Birk Kromann
    I completely understand what you're saying. But when you read this article: http://www.studiodaily.com/2013/01/nikons-d800-gets-down-and-dirty-for-dexter/ It kind of makes you wonder if there is some truth behind it. Jeff Jur even says his colourists had a hard time telling the difference when they were grading them. Even seeing footage from both of them makes it very clear that they're is a difference.
  24. Birk Kromann
    According to DxOMark the dynamic range of the Nikon D800 is a whopping 14.4 stops. I have no problem believing that it is not the same as the Alexa and that the Alexa's 14 stops are calculated differently. It is interesting though that the Canon 5D Mark III only scores a mere 11.7 in the same test, making it almost a half stop less than the 6D (currently the best performing Canon DSLR in the dynamic range category) and 0.2 stops lower than the Mark II Nikon D800: http://www.dxomark.com/Cameras/Nikon/D800 Canon 5D Mark III http://www.dxomark.com/Cameras/Canon/EOS-5D-Mark-III Does anybody else find this a bit peculiar? Especially since the 5D is the "go to" DSLR for filmmakers, heck I even own one my self.

    Well, because they are a photographic company with no dedicated film division. You could ask yourself the same with Arri; why are they so allergic to photo cameras?
