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

What's that noise? Part one: Shedding some light on the sources of noise

How would you react if you were told that the aperture and shutter speed you choose make more difference to image noise than the ISO setting? You might be surprised to discover that a lot of the noise in your images doesn't come from your camera at all: it comes from the light you're capturing. Our own Richard Butler explains. Read more

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

Retro, refined: Fujifilm X100T reviewed

The Fujifilm X100T offers seemingly small improvements on its predecessors, the cult classic X100 and X100S. Its 16MP X-Trans CMOS II sensor and fixed 35mm equiv. f/2 lens are now accompanied by an all electronic shutter mode with increased 1/32000sec maximum speed, redesigned hybrid viewfinder and an upgraded 1.04m dot rear LCD. Find out how much of an impact these incremental updates make. Read review

Rock steady: Olympus OM-D E-M5 II reviewed

The Olympus OM-D E-M5 II follows-up on the groundbreaking original E-M5 and brings extra control points (a lot of them) a 40MP high-res mode, better video, improved image stabilization and a host of other refinements, large and small. We've been shooting a lot with the E-M5 II over the past few weeks, and that work has culminated in a full review, with our usual combination of studio and real-world tests. Click through to see what we think

In the Spotlight: Sony Alpha 7S Review posted

The Sony Alpha 7S is a full-frame interchangeable lens camera sporting a 12.2MP CMOS sensor. It is identical in body design to the Sony a7 and Sony a7R, but don't let that fool you. Unlike the other two, the a7S is specially geared toward video and low-light shooters. It's capable of 1080/60p video with full-sensor readout and can turn out uncompressed 4K footage to an external recorder over HDMI. Read review
