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!

Canon EOS Rebel T6s/T6i (760D/750D) First Impressions Review

The greatest Rebel yet. That's a phrase we mutter about once a year. This time, we really mean it. The Canon EOS Rebel T6s and T6i (known as the 760D and 750D outside of the US) both feature a new 24.2MP APS-C CMOS sensor (up from 18MP on the T5i / 700D) coupled with a new 7560 pixel RGB + IR metering sensor for more accurate metering.

Canon EOS Rebel T6s Review

The greatest Rebel yet. That's a phrase we mutter about once a year. This time, we really mean it, and by a factor of two. The Canon EOS Rebel T6s, as well as its companion, the T6i (known as the 760D and 750D outside of the US) both feature a new 24.2MP APS-C CMOS sensor (up from 18MP on the T5i / 700D) coupled with a new 7560 pixel RGB + IR metering sensor for more accurate metering. Although both cameras are very simiar there are also distinct differences, so each will get its own review. You can read about the T6i here.

Nikon D7200   Review
640

One of our favorite DSLRs in the past few years is the Nikon D7100, which was introduced way back in February 2013. The D7200 isn't a radical upgrade by any means, yet it still adds some important features, most notably a larger buffer, improved autofocus performance in low light, 60p video, Wi-Fi with NFC, and 15% better battery life.

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

Sony SLT-A77 II Review
540

The Sony SLT-A77 II is - as the name implies - an overhaul of the original A77, from from 2011. The A77 Mark II features a new autofocus sensor, and it's much more than a refreshed version of an existing design. Instead the A77 II is built around the AF module with the most focus points of any camera on the market (79), covering an extremely wide area of the frame. It's also rated to work in lighting as low as -2EV. That doesn't necessarily make it quite as sophisticated at pro-grade DSLRs, since they have more cross and diagonal sensor elements, but it looks very impressive for a camera in this part of the market.

[UPDATED] Nikon announces new firmware for 300mm F4 VR to fix blur at certain shutter speeds

Nikon has announced a firmware update for its new AF-S NIKKOR 300mm f/4E PF ED VR, to fix an issue where at certain shutter speeds on D800-series cameras, images can exhibit 'noticeable blur'. According to Nikon, the problem can occur at around 1/125sec with the lens's VR function enabled in either 'Normal' or 'Sport' modes. Users of affected units are encouraged to return their lenses to Nikon where the update will be applied free of charge. Click through for more details

CP+ 2015: Nikon Interview - 'We learned from the D600 episode'

When we attended CP+ earlier this year in Yokohama, Japan we sat down with senior executives from several major camera and lens manufacturers. We were lucky enough to sit down with a number of Nikon engineers to ask them about their overall strategy with respect to FX vs DX, and DSLR vs mirrorless. We were also able to ask pointed technical questions regarding innovative technologies in Nikon cameras, and the answers were very enlightening. Click through to read the interview

In a class of its own: Samsung NX1 review

Samsung's NX1 seemed to offer pretty much every feature possible when we were first briefed about it last year. Its 28.2MP APS-C BSI sensor, hybrid AF system, 4K video and 15 fps continuous shooting with AF have continued to impress us throughout our extensive testing. Can such an innovative on-paper feature set make it a serious competitor to well-established brands in the DSLR and mirrorless worlds? Read review

Samsung NX1  Review
1264

Samsung has been pretty inventive in the digital camera world. It was the first to offer an really extensive Wi-Fi system (which continues to this day), Android-based cameras (though Nikon launched a model at about the same time), and arguably the first dedicated 'selfie cams' with its DualView models.
