About me:

Although I'm a scientist by training, having recently completed my Ph.D in biophysics, photography has always been a huge passion of mine. When I saw an opportunity to meld the two at DPReview, I jumped at it... and now here I am!

New samples from the Sigma 24mm F1.4 DG HSM Art lens

We were recently lucky enough to visit Sigma's factory in Aizu, Japan, where Sigma allowed us to shoot with a pre-production sample of the recently-announced 24mm F1.4 DG HSM Art lens. The wintry landscape of the Fukushima prefecture was a nice contrast to the CP+ convention center where we last gathered some samples with this lens, and our recent samples are more representative of lens performance on a native mount body (Canon 6D). Have a look

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: Hands on with Sigma's new 24mm F1.4 DG HSM Art lens

One of the most interesting lenses at CP+ for enthusiast photographers is Sigma's new 24mm F1.4 DG HSM Art. We made a beeline for the Sigma stand as soon as we arrived on the show floor and got our hands on this intriguing new prime. Click through for some photos and our initial impressions of its build and image quality, based on some initial sample images. 

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

Go wide! Hands-on with Canon's 11-24mm F4 L

Canon's new 11-24mm F4 L wideangle zoom lens has been a long time coming. Canon's widest ever rectilinear zoom by some margin, the new 11-24mm may also challenge Nikon's venerable 14-24mm F2.8 as the tool of choice for landscape, property and architectural photographers. We got our hands on a prototype recently at Canon's US headquarters. Click through for a closer look

CES 2015 Samsung Interview: Mirrorless to outsell DSLRs 'in three years'

Since releasing the NX1 late last year, Samsung has been gathering feedback from users, and is preparing a major firmware update before the end of this month. We made time at CES in Las Vegas to sit down with Byungdeok Nam, Senior Vice President of Samsung's R&D team in the company's Mobile (formerly Digital Imaging) division, to speak about the NX1, the new firmware, and the mirrorless camera market in general. Click through to read our interview

Lytro software update introduces Focus Spread feature

Lytro's processing software just received a significant update. Lytro Desktop 4.1 provides some additional features for users of the Illum light field camera, including Focus Spread, which allows photographers to pick beginning and ending points for depth of focus. Learn more

High-end full frame roundup (2014)

Which high-end full-frame camera should I buy? This roundup contains the majority of current full-frame camera offerings available. Full-frame cameras have image sensors as large as a frame of 35mm film, and for good reason: larger sensors offer the potential for better image quality, low light performance, and dynamic range. If you want a drastic upgrade to the image quality of your phone, or portraits with superior subject to background separation, it’s hard to beat what full-frame offers. 

Pelican Imaging releases light field photos from its mobile imaging array

Pelican Imaging has released a set of re-focusable pictures taken with its light field camera for smartphones. Instead of placing an array of microlenses between the sensor and the main lens, Pelican uses an array of main lenses - each with a sensor behind it. Pelican's offering is more suitable for smartphones, and their sample images allow for re-focusing, changing DOF, and shifting perspective. Click through for more details and links to the images.

UPDATED: Sony's curved sensors may allow for simpler lenses and better images

UPDATE: Sony has released an image taken with its curved sensor, and provided more details on what we might expect from its curved sensor technology. We've updated our previous story with this image and details. Read more
