Canon Asia Posts In-Depth EOS 5DS / 5DS R Developer’s Interview

Canon Asia has posted a two-part developer's interview with the team that designed the EOS 5Ds / 5Ds R cameras. There is a lot of technical information in the articles, but I'm finding the material to be quite fascinating so far (I'm about midway through them right now). [Sean]
 
Canon 5Ds / 5Ds R Developer's Interview Articles
 
[Part 1] Achieving “Speed”, “Comfort” and “Quality”
 
Questions Answered:
 
  • First of all, can you tell us more about the development concept of the EOS 5DS and EOS 5DS R?
  • Can you describe more on the aim and intention on the naming of the models?
  • So now there are five models in the full-frame EOS lineup. Please tell us how the new models are positioned and the division of roles among them.
  • What are the target subjects respectively for the EOS 5DS and EOS 5 DS R?
  • Can I also use these two models for handheld shots and snapshots?
  • What about the internal structure of the EOS 5DS and EOS 5DS R? Are they identical except for the availability of a low-pass filter cancellation feature?
  • The price for the EOS 5DS R is slightly higher. Why is this so?
  • When choosing a lens, what are the points that users need to bear in mind?
  • In what ways are the features and performance enhanced by the use of dual DIGIC 6 image processors?
  • Is there any reason behind the common number “5” for the 50-megapixel resolution and the continuous shooting speed of 5 fps? Was it intentional?
  • Can you tell me more about the enhancements made on the new image sensor, including how you were able to achieve a resolution of about 50 megapixels?
  • The pixel count is more than double that of the EOS 5D Mark III. What were the technological breakthroughs that made this possible?
  • Wouldn’t it be possible to increase the speed if parallel processing were performed by multiple digital front-end processing circuits?
  • Is 16-channel readout drastically different from that by eight channels?
  • How different is the depictive power compared to the class of cameras with about 20 megapixels?
  • Can you explain how the low-pass filter cancellation feature cancels the low-pass filter effect?
  • Besides the restoration process being carried out by low-pass filter 2, is the structure of the EOS 5DS R the same as other models?
  • Why is it possible to restore the extraordinary ray?

[Part 2] Technology Behind the “Ultra-High Resolution”
 
Questions Answered:
 
  • What were the enhancements made to the AF system in response to the larger pixel count?
  • What was the reason for not changing the AF sensor? Was it because the performance of the system on the EOS 5D Mark III was good enough?
  • The maximum resolution of about 50 megapixels and the continuous shooting speed of about 5 fps are simply remarkable. Are there any efforts that are worth special mention?
  • What changes were made to the existing firmware following the upgrade of the pixel count to about 50 megapixels?
  • How is the mirror vibration control system different from the existing ones?
  • Am I right to say that both the existing and new vibration control systems make use of cams, but differ fundamentally in the way the cams are used?
  • Wouldn’t it consume a lot of battery power if the mirror is driven only by the motor?
  • Generally, it is said that camera shake becomes more prominent with a higher pixel count. Is it possible to eliminate all shake-related issues simply by raising the shutter speed?
  • Is there an easy-to-understand way to determine the shutter speed based on the focal length?
  • What are the advantages of the new user-selectable shutter release time lag setting?
  • What efforts were devoted to the body structure and material when addressing camera shake?
  • I realised that a new “Fine Detail” Picture Style has been added when I looked at the features in greater detail. How is it different from the existing Picture Style effects?
  • Can you provide a simple explanation for the entry-level users on the [Fineness], [Strength], and [Threshold] parameters in the sharpness setting?
  • Can you tell us how we can make good use of the Crop Shooting feature?
  • What does the Customizable Quick Control feature do?
  • Compared to the EOS 5D Mark III, what advancements were made to the movie feature?
  • What is the biggest reason for inheriting the design of the EOS 5D Mark III?
B&H has the Canon EOS 5Ds /5Ds R available for preorder.
