Although I'm a scientist by training, having recently completed my Ph.D in biophysics, photography has always been a huge passion of mine. It's been an incredible opportunity to meld these two interests together here at DPReview!

The new Canon 35mm F1.4L II will be a thing of beauty

Canon recently announced an update to the wildly popular 35mm F1.4L lens, originally released in 1998 and undoubtedly designed back in the day for film. The original was always a favorite of our technical editor Rishi Sanyal, so join him as he takes a stroll down memory lane and recounts his favorite aspects of that lens, and what he looks forward to in the update.

Sony Alpha 7R II: Real-world ISO invariance study

The recently announced Sony Alpha 7R II packs a lot of groundbreaking features, and one of its highlights is the new full-frame 42.4MP BSI-CMOS sensor. Sony sensors tend to show very high Raw dynamic range due to low noise characteristics, but we wanted to take a closer look at exactly how little noise the camera itself contributes to images.

Sony Alpha 7R II can match or beat DSLR low light AF performance

When the Sony Alpha 7R II was announced, it promised a lot of game-changing features, but its low light AF capability was an unknown. We've already seen some of the incredible continuous AF abilities of the a7R II, including pinpoint eye AF for even moving subjects, but a lot of pros may be wondering: 'if I ditch my DSLR for some of the advanced AF features the a7R II offers, will I be sacrificing low-light AF performance?' Find out in our video

Under the hood: A closer look at the Sony a7R II

There's a lot of new technology in the Sony a7R II, and here we were briefed on some of the salient features by Sony engineers during a recent Sony Digital Imaging event in Portland, OR. Join our Technical Editor Rishi Sanyal as he explains some of the capabilities of this camera, and why they matter to photographers. Click through to read more

Pocket full of tricks: Sony Cyber-shot DSC-RX100 IV review posted

Sony defined a category when it rolled out the enthusiast-focused Cyber-shot DSC-RX100. This shirt pocketable compact's fourth iteration brings a new 20MP 1"-type stacked CMOS sensor to the table, maintaining an F1.8-2.8, 24-70mm equivalent zoom lens from the preceding model. Our full review analyzes its performance in the field and in our studio. Read more 

Sigma 24-35mm F2 DG HSM A real-world sample gallery posted

There's been a great deal of interest in the Sigma 24-35mm F2 Art lens since its launch last month. And who can blame the internet for getting excited over the world's fastest full-frame zoom? With all of the appeal and high-end touches offered by Sigma's 'Art' series, the 24-35mm just begs to be taken out for a spin - and DPReview's Deputy Editor Rishi Sanyal did just that.

DxOMark: EOS 5DS/R sensor is highest-ranked Canon sensor yet

DxOMark published its report on the 50MP sensor in the Canon's EOS 5DS and 5DS R. They're the best-performing Canon sensors to date, offering massive resolution along along with small dynamic range improvements. Do the cameras raise the bar relative to competitors though? Our technical editor Rishi does a thorough analysis, using DxO's data to pit the 5DS against the Nikon D810. Click through for more

Analysis: Sony a7R II and RX100 IV autofocus systems

Sony recently shook things up with the announcement of the 42.4MP, backside-illuminated full-frame a7R II mirrorless camera, alongside stacked 1"-type sensors in the updates to the popular RX100 and RX10 lines. We put their new AF systems to the test in our brief hands-on time with the cameras recently. See videos of the cameras in action

Production Canon EOS 5DS and 5DS R added to studio test scene

We've updated our Canon EOS 5DS/5DS R First Impressions to include studio test samples from final production versions of the cameras. The 5DS and 5DS R share a 50MP full-frame CMOS sensor and are identical in every way except for one: the 5DS contains an anti-aliasing filter, while the 5DS R has a self-canceling filter. While we've previously tested a beta version of the 5DS R, we've finally been able to put final production versions of the two cameras through our studio. Read more

Eye for an 'i': Canon EOS Rebel T6i review posted

The Canon EOS Rebel T6i (750D) bears a passing resemblance to its Rebel T6s (760D) sibling, but it's a different enough camera to warrant a separate review. Although it shares the same 24.2MP APS-C sensor and 19-point all cross-type AF module as its more expensive sibling, its Hybrid CMOS AF III implementation lacks continuous AF in live view. It also doesn't offer the higher-end controls of the T6s. Does the Rebel T6i hit all the right notes for a beginning photographer? Read more
