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!

CP+ 2015: Sony shows off new technology

We swung by the Sony booth at CP+ 2015 in Yokohama, Japan, where they had displays of the latest technologies in their cameras and lenses, as well as an elaborate diorama of a bird in flight over a fabricated landscape, amongst other things. We even sat down with a couple of engineers at Sony to talk about the Alpha 7 lineup. Check out some of the interesting things we learned during our time here with Sony

CP+ 2015: Ricoh gets serious with new Pentax full-frame zooms

We're at CP+ in Yokohama Japan, where Ricoh is showing off two new Pentax lenses designed for full-frame imaging. Although the company's upcoming full-frame DSLR is still in the mockup stage, the D FA* 70-200mm F2.8ED DC AW and D FA 150-450mm F4.5-5.6 ED DC AW are very real indeed. We snuck into the show early this morning before the crowds arrived, to take a look. Click through for more details and images.

CP+ 2015: Canon shows off new EOS 5DS and 5DS R

By far the biggest lines at this year's CP+ show in Yokohama are at the Canon booth, and they're made up almost entirely of people eager to see just two cameras - the new EOS 5DS and EOS 5DS R. Canon's highest resolution DSLRs by far, both cameras offer an incredible 50MP pixel count, and almost identical ergonomics to the EOS 5D III. Click through for some hands-on pictures

CP+ 2015: Hands-on with Tamron SP 15-30mm F/2.8 Di VC USD

We were intrigued by Tamron's stabilized SP 15-30mm F/2.8 Di VC USD when we first saw it in prototype form at Photokina in September last year. In tbe meantime, Tamron has confirmed pricing and availability for this fast ultra-wideangle zoom and is showing off the new lens at Japan's CP+ show in Yokohama. We're there, and headed straight to Tamron's booth on Saturday to get our hands on the new zoom. Click through for some images

[UPDATED] CP+ 2015: First samples from the Sigma 24mm F1.4 DG HSM Art lens

UPDATED: We're at the CP+ show in Yokohama Japan, where Sigma is showing its brand new 24mm f1.4 full-frame prime lens. The latest in the company's 'Art' series of fast primes, we have high hopes for the new lens based on our extremely positive impressions of the 35mm and 50mm lenses which have come before it. Sigma very kindly let us shoot some sample images on a late pre-production lens and it does indeed look very, very nice. Click through to take a look.

At the Consumer Electronics show in Las Vegas last month, we got our hands on some mockups of Sony's upcoming FE-mount lenses. Originally promised to start shipping this month, Sony has yet to announce final pricing and availability but it is showing working pre-production samples of the lenses at CP+ in Yokohama, Japan. We're there, and we wasted no time getting our hands on the new lenses - now complete with glass inside them, which is welcome change from the last time we saw them. Click through to see for yourselves

CP+ 2015: Canon shows off prototype 120MP CMOS sensor

We're at CP+ in Yokohama, Japan, where Canon is showing off a prototype ultra high-resolution 120MP CMOS sensor. Canon is claiming it has a pixel count equivalent to the number of photoreceptors in a human eye. Its surface area is halfway between APS-C and full-frame, and it appears to be mostly directed at video applications, capable of recording at approximately 60x the resolution of Full HD. Click through to have a look
