Canon EOS 5Ds and EOS 5Ds R DxOMarked (best Canon sensor so far, still lags behind Sony)

d1

DxOMark tested the Canon EOS 5Ds and EOS 5Ds R. They write:

Boasting an unprecedented 50.6Mp resolution, the EOS 5DS and 5DS R offer a unique DSLR shooting solution. What’s more, our industry standard tests have shown these are the best sensor results yet for a Canon chip, with the 5DS cameras offering a small step up for image quality against other full-frame semi-pro models such as the EOS 6D and EOS 5D Mark III. Our measurements show that there’s very little difference between the 5DS and 5DS R sensors, but we’ve seen both models post better scores in print results compared to those on screen.

However, as you can see in the image above, the EOS 5Ds sensor scores lower than the sensors in the Nikon D810 and Sony A7R (first platoon of Sony trolls is ready and can’t wait to spam the comment section). At least the EOS 5Ds doesn’t look so terribly ugly like the Sony A7R. Does Sony not have a design department?

Canon patent for videocamera with compound eye-like lens and light-field technology

eg

Canon filed a patent for what appears to be a Lytro-like technology. The patent refers to a “compound eye” lens, i.e. an optic element with several lenses, each having a different focal distance. Such a device is capable of refocusing images after being taken.

This is called Light-field photography, and Wikipedia has a definition for it:

A light field camera (also known as plenoptic camera) captures information about the intensity of light in a scene, and also captures information about the direction that the light rays are traveling in space. One type of light field camera uses an array of micro-lenses placed in front of an otherwise conventional image sensor; to sense intensity, color, and directional information.

Light-field photography is part of computational photography, and again we have a good definition:

Computational photography or computational imaging refers to digital image capture and processing techniques that use digital computation instead of optical processes. Computational photography can improve the capabilities of a camera, or introduce features that were not possible at all with film based photography, or reduce the cost or reduce the size of camera elements. […] Light field cameras use novel optical elements to capture three dimensional scene information which can then be used to produce 3D images, enhanced of depth-of-field, and selective de-focusing (or “post focus”). Enhanced depth-of-field reduces the need for mechanical focusing systems

However, the patent refers to a video camera. This makes everything more interesting. I couldn’t find any reference to a sensor technology in the patent description. I wonder if this is going to feature a new sensor technology. I am not an expert in this domain, so any help is welcome.
