An ongoing war in eastern Congo has killed more than 5 million people since it started in the early 1990s. How do you draw attention to an armed conflict the world is largely ignoring? Photographer Richard Mosse spent years in the region documenting combatants with infrared film to make the camouflaged soldiers of the Democratic Republic of Congo stand out rather than blend in with their surroundings. Last week, Mosse won the Deutsche Börse Photography Prize for his installation The Enclave. Read more

We set the camera's ND filter to Auto, so we could shoot at wide aperture in good light, and include a real-world shot from the wide and long en of the lens, shot this way.

This is where the iStick, a Kickstarter project comes in. iStick is a USB-drive with an integrated Apple Lightning connector, making it compatible with more recent iPhone, iPad and iPod generations. 

We've just gotten ahold of a full-production Sony Cyber-shot DSC-RX100 III and we've added studio test scene images to our first impressions review. This third generation of Sony's much-acclaimed enthusiast compact features a 20.1 megapixel 1"-type BSI-CMOS sensor, a pop-up electronic viewfinder and a more consistently fast 24-70mm equivalent F1.8-2.8 lens than its predecessor.

We've come to the end of another week here at dpreview, and as our thoughts drift to weekend shooting opportunities, it's time to take things a little less seriously.

You can find it published here (and in our newsletter) every week; we hope you enjoy it, and your weekend.

Roller derby is a bit of an unconventional sport, so it's fitting that James McDaniel uses a somewhat unconventional system to photograph the action.

He hasn't looked back since - see his work and read our Q&A. Read more

The Panasonic Lumix GH4's headline features revolve around its 4K video capture capability, but it's still a very attractive stills camera.

Google again updates its Camera App, this time with self-timer, 16:9 aspect ratio and two more panorama modes. This addresses a point of criticism raised by users when an update in April removed the self-timer function. Other features that come with the new version of the app include wide angle and fisheye panorama options that are based on the Photo Sphere technology. 

If you shoot primarily with wide-angle and ultra wide-angle lenses, you know how difficult it is to add filters. A lot of wide-angle lenses feature deep petal-style lenshoods and lack normal filter threads, making it impossible to add standard threaded filters. The FotodioX WonderPana uses a threaded ring and mount system which enables the attachment of 145mm round filters and square drop-in filters to several ultra wide-angle optics. Read our review

Back in 2012, Jesse Chen - now an engineer at Facebook, but then a fresh graduate - wrote a blog post. In that post he explains how to get rid of the 'ugly copyright overlay' typically used in image proofs, posted online or sent out by professional photographers after events. Essentially a short guide to image theft, the post went unnoticed at the time, but two years later it has come back to haunt Chen, creating a storm of righteous anger from photographers on social media.

The Sigma 50mm F1.4 DG HSM 'Art' is a fast normal prime for full frame cameras, with an unusually complex optical design. However at $950 / £850 it's substantially more expensive than either its predecessor, or Canon and Nikon's 50mm F1.4 lenses.

Update: Following on the release of a significant new v1.4 firmware update for the Pen E-P5 last week, Olympus has issued another fix. Version 1.5 reportedly addresses a problem introduced by 1.4 in which displayed values for shooting parameters did not change.

The latter was added to help prevent blurred images at certain shutter speeds - our main gripe when we reviewed the camera.

The BBC has posted a video looking at Leica's history, on the German company's 100-year anniversary. The very first Leica camera was designed in 1914 by engineer Oskar Barnack, who refined the basic design through multiple iterations, leading all the way to today's digital M-mount rangefinders. In the video, photojournalist and long-time Leica user Tom Stoddart shares his thoughts on the company, and on some of the classic images that have been captured on Leica cameras over the past 100 years.
