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!

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

Opinion: Did Sony just do the impossible?

The Sony a7R II is the company's newest addition to the popular full-frame mirrorless line, and caused quite a stir with its introduction earlier this month. In this opinion piece technical editor Rishi Sanyal explains exactly why he thinks this camera is potentially groundbreaking in many ways. Read more

Return of the Super Rebel: Canon EOS Rebel T6s (760D) in-depth review

Canon's EOS Rebel T6s (760D) is easily the most advanced model yet to enter the company's beginner-friendly DSLR lineup. It offers a new 24.2MP sensor and improved AF and metering systems compared to its predecessor. Its top plate LCD display, quick control dial and continuous AF in live view elevate it above its near-twin, the T6i, while Wi-Fi/NFC round out a solid set of features. We put its improvements to the test in our lab and in the real world. Read review

Enthusiast stalwart: Nikon D7200 in-depth review

Following up the success of Nikon's D7100 is no easy task, but the D7200 promises some notable feature upgrades. Its 24.2MP APS-C sensor is complemented by an updated 51-point AF system that claims sensitivity down to -3EV. Other enhancements include an increased buffer depth, 1080/60p video, built-in Wi-Fi with NFC and improved battery life. We've put Nikon's claims to the test in our in-depth review. Read more

Sources of noise part two: Electronic Noise

Following on our look at the effects of shot noise, our attentions turn to the electronic noise added by your camera. In this second part of the series, we look at read noise and how your sensor's behavior defines what your camera is capable of and consequently, how you should shoot with it. Read more

Dynamic range test added to Canon EOS 5DS R First Impressions Review

Canon's EOS 5DS R tops anything we've seen in its class for resolution, but that's only part of the image quality equation. We put its 50MP sensor to the test in our Raw dynamic range studio and real-world tests. Take a look at the kind of performance you might expect from the 5DS R's (enormous) Raw files. Read more

Speed boost: Sony SLT-A77 II review posted

The Sony SLT-A77 II uses that company's translucent mirror technology in combination with an AF system that Sony claims is dramatically improved over its predecessor. It boasts 12fps continuous shooting with AF, not to mention a 24MP sensor, built-in Wi-Fi with NFC, 2.4M dot OLED viewfinder and a tiliting/swiveling LCD. We put its impressive AF claims to the test. Read review
