Carl Zeiss Apo Sonnar T* 2/135 ZE Canon

Two years after the launch of the first lens in its highly-respected Art line, Sigma has finally added a 85mm f/1.4 model. In case you’re unfamiliar with Sigma’s Global Vision, the Art primes are the company’s high-speed f/1.4 models that have have been developed to compete in image quality with the very best lenses from Canon and Nikon, and can even give legendary lens maker Zeiss a run for its money.

We’ve tested 130 lenses on Canon’s flagship camera, the full-frame 18-Mpix Canon EOS-1D X Mk II, covering focal lengths ranging from an incredibly wide 11mm up to a super-telephoto 600mm.

We’ve split the results between primes and zooms and then arranged them into three groups according to use. This equates to ultra-wide and wide-angle, standard, and telephoto to help you narrow down the best performer in each.

However, this time we’ve compared lenses from the perspective of the camera’s intended market — the photojournalist. While they’re not really any different from the next photographer when it comes to choosing focal length, there are some models that perhaps require further consideration.

We’ve tested 130 lenses on the recently-introduced full-frame 30-Mpix Canon EOS 5D Mk IV, covering focal lengths ranging from an ultra-wide angle 11mm to 600mm super-telephoto.

In Part 2 of our best lenses for the Canon EOS 5DS R review, we’re looking at the best optics for travel, wildlife, portrait and event photography. Whether you’re looking for a versatile zoom for weddings, a prime for the best quality portraits, or a professional sports and wildlife lens, we’ve got all the data you need. So let’s analyze the scores in five different categories — short telephoto prime, long telephoto prime, “fast” telephoto zoom, “slow” telephoto zoom, and super-zoom — to discover the best-performing lenses in each group.

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.

Launched side-by-side, the EOS 760D and EOS 750D (a.k.a. T6s and T6i in North America, respectively) share a lot in common, including the same high-resolution 24.2-Mpix APS-C CMOS sensor, complete with Canon’s Hybrid CMOS AF III for fast and accurate focusing. We’ve put the two models through our lab tests, along with a wide range of native and third-party Canon-mount lenses. Read on to find out how these models perform.

In Part 2 of “Best lenses for the EOS 7D Mark II,” we’re looking at the performance of primes on Canon’s flagship APS-C sensor.We’ve analyzed over 300 fixed-focal-length lenses on the EOS 7D Mark II, including own-brand Canon EF and EF-S lenses that are designed specifically for use on the Canon APS-C sensor. Covering a range of third-party alternatives as well, our comprehensive analysis will help you pick out a prime, whatever your photographic needs.

Launched a little over 2-years ago, the first Zeiss Otus model was a triumph in optical and mechanical perfection, and now Zeiss has added a second model to the range, and high speed 85mm with a heady mix of six anomalous dispersion glass elements, one asphere and a floating system to reduce aberrations at close range.  Read on to see how well this new exotic model performs.

With a full-frame 18-Mpix CMOS sensor and twin Digic 5+ processers that’s capable of continuous bursts of up 12 fps – the fastest of any professional DSLR currently - the Canon EOS-1 Dx is the firm’s flagship press camera. We’ve assessed it with over 100 EF mount lenses, to see how well they perform. Read on to find out which models are the best optically and which, if any, you should avoid.

In the first part of our comprehensive lens recommendations for the new entry-level Canon EOS Rebel T5 / 1200D, we’ve assessed a raft of primes from both the maker and third parties to see how well they perform on the camera. As well as highlighting the best performers we’ve also taken a closer look at the best on a budget.
