The camera is built around a Canon EF mount and an internal SSD recorder to cope with the data rates. Blackmagic says it will be available from July 2013.

Imaging Resource has published an interesting article by Steve Meltzer, which examines the mystery of the so-called 'Mexican suitcase' - a long-lost collection of images taken by the late Robert Capa. Before escaping Europe ahead of the Nazi invasion of France, Capa entrusted a large number of negatives to a friend for safekeeping. The collection went missing, and was presumed lost for decades until being identified in Mexico in 1995. Robert Capa's brother, Cornell Capa, finally got to see the long-lost negatives in 1997 - forty three years after his brother's death. Click through for a link to the full story.

Following the recent public release of Adobe Camera Raw 7.4, we've updated our studio comparison database with new raw conversions of files from the Fujifilm X-Pro 1, X-E1 and X100S. We've been using the release candidate version of ACR 7.4 for some time, which contained significant improvements to Adobe's treatment of files from Fujifilm's X-Trans sensors. The official public release version of ACR 7.4 brings some further (very minor) tweaks.

With the announcement of Facebook Home, a launcher or 'skin' that can be installed on top of the Android operating system of your mobile phone, the social networking giant has instantly transformed the role and importance of images in social media, bringing them to the forefront in a way that not even its desktop Timeline feature could. We are having a closer look at what Facebook Home is and what it means for image sharing.

There is currently no information about the XE series' price and availability.

In the course of preparing our in-depth review of the Nikon D7100, we're exploring the potential image quality advantages of Nikon's decision to forgo an optical low pass filter (OLPF). As part of this process, we compared the D7100 alongside the Nikon D5200, which also uses a 24MP APS-C sensor, but includes an OLPF and have just added the results to our hands-on preview. Does the D7100's lack of OLPF really make a difference? Click through to read what we've found.

Celebrated American photographer William Eggleston won a legal victory when a US District Court judge dismissed a claim of fraudulent and negligent misrepresentation brought by collector Jonathan Sobel. Sobel, an avid Eggleston collector, argued that by creating a new set of large format inkjet prints beyond the 30-year old dye transfer print limited edition of the same image, Eggleston was diluting the value of the earlier prints, one of which Sobel owned.

Nikon has come under fire from animal welfare groups and some wildlife photographers over its new 'Monarch' line of rifle scopes, designed for game hunting. Marketed as being 'Engineered for Safari' Nikon's Sport Optics division claims that the new Monarch-series scopes are created 'for those seeking dangerous game adventure on the Dark Continent' - an archaic term for Africa. Nikon has manufactured scopes like this for many years, and is not alone (so does Pentax, Leica and others) but the marketing behind its newest Monarch line has caused a degree of anger.

NAB 2013: Canon has announced the development of a 35mm prime lens in its Cinema EOS range. It is designed to be used on movie cameras with image sensors up to 35mm full frame in size, and includes a range of features optimized for movie shooting. The company has not finalized its specifications and pricing, but says it will release further details in due course. However as the Cinema EOS primes offer T-stops that correlate closely with existing L-series primes, it seems likely the 35mm will be approximately T1.5, and of course use the EF mount.

Fujifilm makes some grand claims for its optical performance; click through to see if it lives up to them in our detailed review.

Photographer Nick Laham found himself in a tight spot as he squeezed into a locker room bathroom stall to take portraits of the New York Yankees during a spring training session earlier this year. He used both his DSLR and his smartphone to take the photos, but it was his iPhone-captured and Instagram-processed images that earned the attention of the New York Times, which ran Laham's portrait of baseball great Alex Rodriguez on the front page of the Sunday edition.
