Canon 5DS 50-megapixel

At last Canon have responded to Nikon and produced a camera with significantly more pixels, a 50 megapixel camera will produce approximately a 150mb file! It is not one new camera but 2, the 5Ds and the 5DS R The planned release is June so start saving.

Canon’s new full-frame sensor offers a resolution of 50.6 million pixels (megapixels). That’s 40% more than the Nikon D800/D810, a camera which caused jaws to drop on its own launch Comparisons with Canon’s own cameras are even more stark. The EOS 5D Mark III was previously Canon’s highest resolution DSLR, with 22 million pixels – but the 5DS more than doubles this at a stroke writes Techradar

This kind of resolution might be overkill for the average amateur photographer, but for professionals it could be crucial. It could even take away the need to move up to the much more expensive world of medium format digital photography, and will be particularly well-suited to landscapes, architecture, fashion and portrait photography. It provides the kind of resolution needed for large-scale displays like advertising billboards or posters.

Professionals are the main target, but Canon also talks about ‘personal’ photography. The EOS 5DS isn’t cheap, but it’s not unattainable either. It goes on sale from June 2015 at a price of £3,000/US$3700 (about AU$4726), which is not a whole lot more than the EOS 5D Mark III

The 5DS R is sharper still

When Nikon launched the D800 in 2012, it also announced a variant the D800E. Until that point, all DSLRs had an optical ‘low-pass’ filter in front of the sensor to prevent moiré (interference) effects with fine patterns and textures. This slightly softens fine detail as a side-effect, and the D800E variant had the low pass filter effect removed (reduced actually – it was removed entirely for the D810).

Canon has done the same. The 5DS is the ‘regular’ version with a low pass filter, while the 5D R has the low pass effect removed.

In fact, apart from the resolution and a some external details, the 5DS is practically the same as the 5D Mark III. The 5D Mark III will continue alongside the new models too, and not just as a cheaper but outdated predecessor – it’s better in low light, for a start. The 5DS has a maximum non-expanded ISO of 6400, but the 5D Mark III goes up to ISO 12800

Canon EOS 5DS / SR key features

  • 50MP CMOS sensor
  • 5fps continuous shooting
  • ISO 100-6400 (Extends to 12,800)
  • 61-point AF module with input from 150k pixel metering sensor
  • Dual Digic 6 processors
  • 3.0″ 1.04m dot LCD
  • CF & SD slots (UHS-I compatible)
  • 1080/30p video
  • M-Raw and S-Raw down-sampled formats
  • 30MP APS-H crop and 19.6MP APS-C crop modes
  • USB 3.0 interface

 

It is interesting that as DP Review mention having such resolution means that focus and stability becomes more of an issue, this implies these cameras are better suited to tripod based photography

Most of the big new features on the high-res 5Ds are about ensuring you’re able to get the best of the cameras’ extra resolution. Our experiences with the Nikon D8X0 series cameras has shown us that simply having a high resolution sensor isn’t enough: to take full advantage of it you need to really obsess about stability.

To this end, Canon has reinforced the tripod socket and surrounding area to allow stable engagement with a tripod. It has also used a more controllable, motorized mirror mechanism, like the one in the EOS 7D II, that allows a deceleration step before the mirror hits its upper position – reducing mirror slap.

The third change a revised mirror lock-up mode that allows you to specify an automatic delay between the mirror being raised and the shutter opening to start the exposure. It allows the user to choose the shortest possible delay that has allowed mirror vibration to subside: maximizing sharpness while minimizing the loss of responsiveness.

A series of features in the EOS 5DS and S R are ones we first saw in the EOS 7D Mark II. This includes the flicker detection function that warns you of lighting flicker and can synchronize the camera’s continuous shooting so that it only fires at the brightest moments to ensure consistent exposure (rather than the constant variation you can otherwise get in such situations).

Two other 7D II features to make an appearance in 5D camera for the first time are the built-in intervalometer function that can be used to shoot time lapse sequences. And, as a first for Canon, these can then be combined in-camera to create a 1080/24p time-lapse movie.
