Richard Butler
Technical Editor

Richard graduated as a scientist but had a lot more fun writing and shooting for his university magazine. A number of years spent variously as a reporter, writer and editor on science and engineering titles combined his knowledge of science with his interest in images and words. But it was spotting the connections between emission spectra, white balance and all the nonsense he'd taught himself playing around in Photoshop that helped kindle an interest in digital photography. Searching for a camera led to him discovering DPReview and Richard was recruited by Phil Askey in 2007. He's been combining his love of photography, communication and attention to detail (pedantry?) ever since.

He has unusually strong opinions about lenses for the APS-C format.

Panasonic Lumix DC-G100/G110 review

The Panasonic Lumix DC-G100 (G110 in some regions) is a mirrorless camera designed for vlogging. Its 20MP Four Thirds sensor is paired with clever tracking audio technology, but we have our reservations.

Fujifilm GFX 100S review

The GFX 100S fits most of the capabilities of the GFX 100 into a smaller and more affordable body. We've tested what the camera offers to see who it might make sense for.

Sony a1 review
2606

The Sony Alpha 1 is Sony's flagship mirrorless camera for, well, just about anything. With a 50MP sensor, it gives you tons of resolution, but it also lets you fire off burst images at 30 fps for fast action sports. Add in 8K video capture and you have a really impressive package.

Canon EOS R3: What do we know, and what can it tell us about a future 'EOS-R1'?

Canon has just announced the development of what will be the highest-speed RF-mount camera yet, the EOS R3. It looks like a really interesting camera, but the R3 also points toward something else coming in the future; something even more capable. Here's what we know.

If you shoot Log on the Canon EOS R5, you should shoot C-Log3. Here's why.

Canon has just added its Canon Log 3 gamma profile to the EOS R5. We take a closer look at what it is, how it compares to the Canon Log profile and when you should use it.

Pentax K-3 Mark III initial review

The Pentax K-3 Mark III is that rarest of things: a completely new DSLR. We've got hands-on with the camera to find out just what's changed in the six years since the Mark II. The answer is: almost everything.

Sigma fp L initial review

The Sigma fp L is a high-resolution development of the company's compact full-frame interchangeable lens camera. It gains a 61MP BSI-CMOS sensor, providing a more stills-focused platform than the original fp 24MP L-mount mirrorless camera. Learn more about it in our initial review.

All about the Kei: a 4K video from the Sony a1's 8K capture

8K is arguably more useful as a way to capture flexible 4K than as an output resolution, at the moment, so we shot a 4K-from-8K video project with the Sony a1. See for yourself how the 10-bit S-Log3 footage came out.

Nikon Z7 II review
1510

With dual processors, dual card slots and more, Nikon's Z7 Mark II is a more capable camera than its predecessor in every way. But we have a few remaining qualms: find out just what we make of the Z7 II.

Why the speed of Stacked CMOS is key to Nikon's pro mirrorless camera

Nikon says its professional mirrorless camera will use a Stacked CMOS sensor. We look at why this one statement holds so much promise for the camera's performance.
