CP+ 2015: A closer look at Canon's forthcoming PowerShot G3X

Alongside new DSLRs and the EOS M3, Canon quietly announced a new high-end PowerShot last week. The G3 X hasn't been released yet, but we're at the CP+ show in Yokohama Japan, where a prototype (displayed under glass) offers some clues to its specification and ergonomics. Click through for some images and a little informed guesswork. 

CP+ 2015: Hands-on with new Pentax K-S2

The Pentax K-S2 doesn't replace the K-S1, but sits above it in Ricoh's Pentax lineup. And quite right too - it's a considerably more serious camera, even if we do miss the shiny disco lights on the handgrip. We're at the CP+ show in Yokohama Japan, where Ricoh is showing off its new 20MP APS-C DLSR, in all manner of color combinations. Click through for some hands-on images

CP+ 2015: Up close and personal with Ricoh's full-frame Pentax mockup

After announcing the development of a full-frame DSLR recently, Ricoh is showing a very early mockup at the CP+ show in Yokohama Japan. Although details are extremely limited (limited, in fact, to the words 'Full-frame' in the press release and 'Pentax' written on the front) Ricoh's mockup does give some clues as to the camera's specification. Kind of. Click through for images and some - frankly - rampant speculation. 

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

Nikon D750 Review
1978

The D750 is Nikon's third full-frame DSLR this year, and for a lot of our readers, it might be the most significant. Sitting between the more affordable D610 and the pro-grade, high-resolution D810, the D750 borrows elements from both cameras. Impressively though - with the exception of its 24 megapixel sensor - the D750's build quality, ergonomics and feature set have much more in common with the more expensive of the two.

Canon EOS 7D Mark II Review

In the five years since its launch, the Canon EOS 7D has gone from being a cutting-edge piece of technology to an apparent remnant of a bygone age. Not simply in the sense that its technology has been superseded, but also in that the idea of a pro-grade APS-C DSLR seemed to one whose time had passed.

Take two: Canon EOS 7D Mark II Review

Canon's EOS 7D Mark II was a long time coming. It arrived in time for Photokina 2014, combining a pro-grade AF module with a 20MP APS-C CMOS sensor using Dual-Pixel AF. The 7D II also provides 10 fps continuous shooting, a 150,000 RGB +IR pixel metering sensor and 1080/60p video recording. Our full review takes an in-depth look at its performance. Read review

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.
