  1. Agree on the 720p unfortunately when I was shooting I didnt have a comparison in mind so I didnt ensure both were 1080p or even 4K. But if its not immediately obvious that one is 720 without me mentioning it then its a testament to how nice the 720p in on the A7s.

    ​The cage is from Motion9 called the A7s Cube cage. I can honestly say this cage is AMAZING!! Sounds silly to say about a cage but this cage is so well thought out and so well machined and finished.  I have a Movcam top plate on the F5 and it was very poorly machined with sharp edges. Machining aside the Motion9 cage is precision and a very snug fit around the A7s and the thumb rest is excellent. They also have rails and their own battery option. 

    The Shogun was positioned with a Noga style arm. Easy to reposition.

    The box to the left of the cage is actually part of the cage. It is an ingenious way to clamp the HDMI and other cables exiting the camera. And its a handle!!

     

    ​Thanks very much for that information.

    Regarding the Noga Style Arm, I was wondering what the unfinished metal plate at the very end was -- and if the Shogun was also actually laying on a flat black metal support as can almost be seen in this photo.

    Of course, my eyes maybe playing tricks on me.

     

  2. I know Avid announced changees to DnxHD to include 2k, 4k and 6k but Im not sure when this is going to be available.

    ​These larger raster sizes are already available in Avid Media Composer 8.3, which was released in December.

    The new codecs are called DNxHR (as opposed to DNxHD) and I expect they will ripple through 3rd party products (Resolve, etc.) in the very near future.

  3. holy crap, internal 4k on the a7s?  I really do hope this becomes true.

    ​Extreme!y unlikely.  Irresponsible and sensational rumor that entirely deviates from the purported statement that was made.

    Edit:  of course, I'm referring to the original rumor site.

  4. Thanks for this review.

    I had pre-ordered the Shogun when it was first announced, but canceled it when the delays started cascading.

    Based on your (and other) reviews, this version of the product clearly has applications -- but it seems Atomos missed more than one target in terms of the design, and I'd much rather wait for v.2.

    Unfortunately, I can't see them delivering a substantially improved revision in the near term, as it would completely alienate v.1 owners.  And, by then, there will certainly be more cameras recording 4k internally. 

    Finally, I'd like to say that "Ethic Statements" aside, I find your reviews to be honest with absolutely no pandering.

     

  5. Let's not write it off completely - it might do a hybrid IS when a Sony OIS lens is attached, using OIS for the high frequencies and IBIS for the larger ones on all 5 axis.

     

    Thank you for this thought.

     

    This is potentially a critically important point.  I can easily imagine a scenario where the IBIS is optimized to work in concert with the stabilization available in OIS lenses.

     

    And where that superior performance is not fully available with 3rd party lenses.

     

    I wish we could see a test using Sony's FE 16-35, FE 24-70 or FE 70-200.

  6. Rather than bog this thread down with more opinions regarding Sony's color science, since you seem to be possibly experimenting with Resolve, it may make sense for you to explore the new Color Match feature.  One of many Resolve Color Match demo videos on the Internet:

     

     

    The smallest and least expensive compatible color targets are these two:

    Importantly, I'm not suggesting that you have to shoot a chart for every one of your setups. 

     

    However, this very useful tool will quickly get you into the ballpark and you will be able to see what it is doing to bring your images into alignment.

     

    And once you settle on a particular profile, you can use this tool to create LUTs that can be used in other software platforms.

    HTH.  Good luck.

  7. Not sure this is possible, but it is very frustrating to receive a thread notification email that does not provide a link to the new posts.

     

    The only link provided in the email is to the first page of the thread -- meaning, one has to frequently scroll through multiple pages just to get to the new posts.

     

    Every other forum I subscribe to provides a link to the newest posts (which are also included in the email) -- it would be surprising if this one did not offer that option.

  8. Two brief comments about the new website layout:

     

    1.  I miss being able to access the Comments without having to scroll all the way down the page of the article.  I liked being able access them directly using the link in the article header.

     

    2.  The home page correctly scrolls such that the EOSHD header leaves the frame and the entire screen real estate is available for reading articles.  The forum page, on the other hand, has a persistent EOSHD header which (when reading on a 7" tablet) leaves very little available space for the content.  Selfishly speaking, I'd rather the forum pages scrolled the same way that the home page scroll, as it's really hard to read 4 pages of posts using two or three vertical inches of screen space (on a tablet, that is).

     

    Thanks for listening.

  9. if you want to use a clear uv as a lens protector - you only need to have this on the lens when you are not using an ND filter or polorizer

     

    So I personally would not include it at all in you filter stack as its just another piece of glass to cause flare and internal bounce reflections - this happens when you stack filters - less is more!!

     

    Thanks for your response.

     

    So, I guess the next question would be:  

     

    In terms of using step-up rings to standardize the thread sizes of all of my lenses, is there an optical difference (or disadvantage) to mounting a filter (Variable ND, Polarizer or UV) on a step-up ring -- as opposed to directly onto the lens? 

  10. From an optical point of view, is there a "best practice" regarding how to stack multiple filters?

    More specifically, let's say I have 4 lenses having varying thread diameters (16-35, 24-70, 70-200 and a Macro).

    In order to protect the front elements, I decide to buy a Clear UV filter for each lens.

    Then, recognizing that I might also need a Variable ND and Polarizing Filter for each lens, but not wanting to buy 8 additional redundant filters, I decide to use Step-Up rings for each lens to "equalize" the lenses to a common larger thread size -- let's say to 72mm.

    The question is:

    Should the Clear UV filters be directly connected to each lens -- or should they be attached to the Step-Up filter of each lens? 

    In other words, should the order be:

    • Lens > Clear UV > Step-Up Ring >Variable ND or Polarizing

    Or should it be:

    • Lens > Step-Up Ring > Clear UV > Variable ND or Polarizing

    And, if I were to consider buying some magnetic Xume Quick Release Adapters to allow for quicker ND/Polarizing lens changes, would that change the equation?

    In other words, with Xume adapters, should the order be:

    • Lens > Clear UV > Step-Up Ring > Xume Adapter > Variable ND or Polarizing

    Or should it be:

    • Lens > Step-Up Ring > Clear UV > Xume Adapter > Variable ND or Polarizing

    Thanks in advance for any advice.

  11. The Micro USB port is directly adjacent to the spring-mounted lens release lever -- under the oblong black plastic cap.

     

    I seem to recall older versions of this product possibly having a proprietary port (not USB) that was unusable by the customer.

     

    Be sure to look at the back of the plastic case your adapter came in to determine exactly which version was sold to you.

     

    In the upper right corner of the foil label it should say "Mark IV"

  12. This document seems to support that premise:

     

    Clean HDMI Output
    1080 60i compatible device:  3840 × 2160(30p/24p) / 1920 × 1080(60p/24p) / 1920 × 1080(60i),YCbCr 4:2:2 8bit/ RGB 8bit

     

    If that is true, it is unfortunate, as it means that 120fps on the A7s will always be limited to 4:2:0 and 50Mbit compression.

     

    It would be nice to get corroboration on this.
