Canon EOS 5Ds image quality seen through print performance


A definitely interesting and pretty technical article about the Canon EOS 5Ds by Luminous Landscape. The 5Ds performance from the point of view of how much the 50MP matter when it comes to print performance. Comparison with the EOS 1Ds Mark III is discussed.

The article is not easy to sum up. It comes with sample pics, pixel peeping, and more in-depth analysis Giving it a try with a quote:

[…] the 5Ds images are notably superior in resolution, but when it comes to making prints there is an important consideration. Not one of the half dozen non photographers I showed the prints to mentioned detail in the images. When asked for differences, most popular was spotting the slightly different view, next up was that the brickwork was ‘a bit redder’ in one print.

That’s not the whole story. Head over to LL for the article.

New Canon videos celebrate 10 years anniversary of EOS 5D series

Canon released 2 new videos to celebrate the 10 years anniversary of the company’s winning EOS 5D series. The video below shows highlights of an interview with the developers of the EOS 5D series. You may also be interested in a long series of technical articles dedicated to the EOS 5D and its successors.

The EOS 5D line was a game changer in many aspects. Just think what the EOS 5D Mark II made for videographers. And we are looking forward to another milestone with the upcoming EOS 5D Mark IV.

The latest addition to the EOS 5D series are the Canon EOS 5Ds (B&H Photo, Adorama, Amazon USA, Amazon Canada, Canon Canada, Canon USA) and EOS 5Ds R (B&H Photo, Adorama, Amazon USA, Amazon Canada, Canon Canada, Canon USA).

Dragonfly Telephoto Array is made of 10 Canon 400mm f/2.8 IS II lenses, and sees the faint structure of the universe

Dragonfly Telephoto Array

We wrote about this project time ago. Now it evolved and we won’t miss the news.

The Dragonfly Telephoto Array belongs to the University of Toronto’s Dunlap Institute for Astronomy and Astrophysics. The ten EF 400mm f/2.8L IS II make up for approximately $100,000. The lenses were mounted on ten SBIG STF-8300M CCD cameras, and that makes up for another whooping $20,000. There is also a Paramount ME-II robotic telescope involved, which is yours for just $135,000.

What is the thing good for? Quoting:

Dragonfly is designed to reveal the faint structure [of the universe] by greatly reducing scattered light and internal reflections within its optics. It achieves this using ten, commercially available Canon 400mm lenses with unprecedented nano-fabricated coatings with sub-wavelength structure on optical glasses.

There are some research paper available if you are into this sort of scientific things:

The technology behind the Canon EOS 5DS and EOS 5DS R – Interview with developers


Canon Asia posted an interview with the deveolpment team behind the Canon EOS 5Ds and EOS 5Ds R. An excerpt:

Question: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?

Answer: Yes, you are right. The EOS 5D Mark III and the EOS 5DS series share exactly the same principles of forming an image on the focal plane. It can handle any number of pixels as long as the level of accuracy is maintained. The existing AF sensor is perfectly fine since it has a sufficiently high level of detection performance.


Question: What changes were made to the existing firmware following the upgrade of the pixel count to about 50 megapixels?

Answer: The huge amount of data has a significant impact on the firmware. In order to ensure speedy and smooth data processing under such conditions, advanced and complex processes are needed, such as parallel processing while switching between the memory spaces. As there is limited space in the built-in memory of the camera, it is important to consider how this space can be utilised most effectively.
