Canon EOS 5DS : Tests and Reviews

The Sony SLT A99 II is the Japanese electronic giant’s latest full-frame, DSLR-style, interchangeable-lens camera. Packing a 42Mp backside-illuminated (BSI) CMOS sensor, the A99 II offers a significant jump in resolution over its predecessor and achieves an impressive overall DxOMark score of 92 points. Benefiting from a pixel arrangement that increases the volume and quality of light captured by its imaging elements, a BSI sensor improves low-light image quality.

Canon’s iconic EOS 5D series of full-frame DSLRs have had wide appeal with both pro and enthusiast photographers, blending great image quality and good features in a more affordable mid-range body design. Boasting a significant number of upgrades over its predecessor, including increased resolution, an updated autofocus system, Dual Pixel RAW capture, improved metering and 4K-video capture, the latest Mark IV looks like a mouth-watering prospect for the still photographer.

As the eagerly-awaited successor to the 16-Mpix D4s, the new Nikon D5 boasts an all-new 20.8-Mpix full-frame CMOS sensor with ISO up to 3.28M (yes, million), 12 fps continuous shooting, a new 153-point AF system, and 4K (UHD) video capabilities. Read on to find out how well the Nikon D5 performs.

Carl Zeiss’s latest range of Batis lenses has been specifically designed for the Sony A7 series of full-frame mirrorless cameras such as the Sony A7R II and Sony A7S II. Together with the legendary optical precision and outstanding build quality for which Carl Zeiss lenses are known, the new Batis lenses also feature autofocus and an innovative OLED display on the lens barrel that gives both focus distance and depth-of-field information. The first new lenses released in the Zeiss Batis lineup are the 25mm f/2 wide-angle prime and 85mm f/1.8 short telephoto prime.

Tamron has added a new moderate wide-angle Nikon F-mount SP 35mm f/1.8 Di VC USD lens to its range. It features a sophisticated optical layout with VC image stabilization, two ED glass elements and two aspheres. Read on to find out how well this new model performs.

Our technicians have tested no fewer than 130 lenses on Canon’s 50.6Mp EOS 5DS R Digital SLR. With the results for both prime and zoom lenses covering a diverse range of focal lengths, we’ve got all the data you need for picking out the right lens. In Part 1 of our three-part review, we bring you the analyzed and verified scores for standard zoom lenses as well as 35mm, 50mm and 85mm primes on the Canon EOS 5DS R.

Early in the year Canon updated its high-speed 35mm f/1.4 L series prime, which is the first revamp of this model since the original was introduced in 1998.  Read on to find out how well this new lens performs.

Building on the success of the full-frame 36-Mpix Sony A7R, the recently announced update to that model looks to be one of the most promising cameras of the year. Along with a slight increase in pixel count over the original, the sensor in the 42-Mpix A7R II offers BSI architecture and on-chip PDAF with 399 points. Read on to find out how well this new sensor performs.

Launched at the same time as the 50-MPix EOS 5DS and 5DSR DSLRs, the EF 11-24mm f4L USM is the widest rectilinear lens for photographers in the world. Read on to find out how well this brand-new model performs.

Boasting a monster 50.6Mp resolution, the $3699 EOS 5DS and $3899 5DS R (which differs due to its low-pass cancellation filter), become the new top-ranked Canon sensors on our database. With screen and print scores checked and verified, let’s analyze the results to see how Canon’s latest full-frame sensor stacks up against the competition.
