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.

OM System OM-1 review

It says Olympus on the front, but the OM System OM-1 is about the future, not the past. It may still produce 20MP files, but a quad-pixel AF Stacked CMOS sensor, 50 fps shooting with full AF and genuine, IP rated, weather sealing show OM Digital Solutions' ambition. See what we thought.

Nikon Z9 review: a DSLR-like stills/video monster

The Nikon Z9 uses a stacked CMOS sensor to power its first pro-level mirrorless camera. With firmware 2.0 now available, we've reviewed the fast-shooting stills and video camera designed to win-over Nikon's professional DSLR users.

Try and try again: how the Nikon Z9 supports the sports photographer

Working towards the Nikon Z9 review, editor Richard Butler has been shooting a series of rugby matches. In this article he explains how the Z9 – and a lot of practice from the sidelines – is helping him become a better sports photographer.

Quad Bayer vs Quad Pixel AF: what they are, how they work and how they differ

Quad Bayer and Quad Pixel AF are two very similar technologies with utterly different impact on the cameras that use them. Find out what OM Digital Solutions is doing with its OM-1 and learn about the secret behind two of the best video ILCs on the market.

Panasonic GH6 looks good for most shooting, but low ISO DR falls behind

We've shot and examined our studio scene, and its images are a match for the OM System OM-1 in a lot of circumstances. Digging into the shadows shows there's a dynamic range cost at low ISO for this clever, fast sensor.

Hands-on with the Sony FE PZ 16-35mm F4 G

Join us as we take a closer look at Sony's new 16-35mm F4 power zoom, and investigate some of the less obvious aspects of its design.

Nikon Z9 studio scene shows great speed comes at little cost

The Nikon Z9 has impressed us with its speed and autofocus but what's the image quality like? We found there's very little penalty to be paid for the other capabilities the stacked CMOS sensor brings.

Wayback Machine: The evolution of Panasonic's GH-series cameras

It's hard to believe that Panasonic's video-centric GH series is 13 years old. Over that time, it's evolved from a scrappy upstart video camera into a product line with some of the most advanced video features on the market. We take a look back to see how far the GH series – and mirrorless video in general – has come.

We shot sports with the OM System OM-1 - This is what we learned

The OM System OM-1 promises X-type PDAF and unprecedented burst speeds. Is it enough to shoot a professional rugby match? At night? As Richard Butler discovered, the OM-1 may be a rookie, but it has a good range of skills and can mix it up with the big boys.

Researchers use quantum dots to create high resolution three-layer sensor

Researchers in the US and Korea are developing three-layered sensors based on quantum dots that promise low-cost, flexible, high-dynamic range sensors without the need for demosaicing.
