Roger Cicala cock-a-hoop* over Sigma's 35mm F1.4 DG HSM

Lensrentals' Roger Cicala hasn't always been a fan of Sigma's lenses but the company's latest 35mm F1.4 seems to have got him pretty excited. He's written a very positive first impressions blog post, considering the build and test data from the first sample he's received. As usual, he's very careful to stress the limitations of what he's reporting - specifically that these are early impressions, based on a single lens that he's had little chance to actually take photos with. However, he's also someone with immense experience with lenses, and is in the unusual position of having had the opportunity to strip the lens down, so we found his insight interesting.

Photographer creates time-lapse showing D600 'dust' accumulation

Canadian photographer Kyle Clemens has created a timelapse video which shows the slow accumulation of debris on the sensor of his brand new Nikon D600. When we reviewed the D600 we expressed concern about the propensity of its sensor to gather specks of debris, and Clements raises the troubling possibility that whatever it is that's ending up on the D600's sensor could be coming from inside the camera. Click through for the full video and a link to Kyle Clements' blog where he investigates the issue. 

Bryce Bayer, inventer of Bayer Filter, passes away aged 83

Imaging Resource has published an obituary of Bryce Bayer, who passed away recently. Often called the 'father of digital imaging', former Kodak scientist Bryce Bayer invented and gave his name to the so-called 'Bayer Filter' - a mosaic pattern of red, green and blue filters which allows silicon sensors that are only sensitive to luminance to capture information about the color in a scene. Patented in 1976, the RGBG Bayer Filter has since become essentially ubiquitous, being used in virtually all digital imaging systems from medium-format backs to smartphones.

Just Posted: Sigma 18-250mm f/3.5-6.3 DC Macro OS HSM Review

Just Posted: Our review of the Sigma 18-250mm f/3.5-6.3 DC Macro OS HSM. The latest version of Sigma's stabilized superzoom is smaller and lighter than the existing non-macro version, yet is able to add improved close-focus performance, helping it compete with the similarly-sized Tamron 18-270mm F/3.5-6.3 VC PZD. These long-range all-rounders are a popular choice, so we've had a look at how Sigma's latest performs. We've also added DxOMark's test data for a selection of its competitors, to give a sense of context.

Canon EOS 6D sample images added to hands-on preview

We've added a gallery of real-world and studio images to our Canon EOS 6D preview. The EOS 6D won't be available until at least December but we've been able to borrow a pre-production model for which we've been allowed to post samples. We've shot with the camera in a series of lighting conditions, using a variety of lenses, including the EF 24-70mm f/2.8L II USM and the EF 70-300mm f/4-5.6L IS USM. We've also shot an ISO sequence under challenging low-color-temperature artificial light. Click here to see how Canon's latest full-frame challenger performs.

Just Posted: Our samples gallery from the Tamron SP 24-70mm F/2.8 Di VC USD. The company's latest fast maximum aperture, stabilized standard zoom was announced back in February, but really comes into its own with the recent announcements of more affordable full-frame bodies from Canon and Nikon. We've put together a gallery of images shot in a variety of situations with the Canon EOS 5D Mark III to give a taste for what it can do.

Just Posted: Panasonic Lumix DMC-FZ200 Review

We've just published a review of Panasonic's flagship super-zoom camera, the Lumix DMC-FZ200. The FZ200 goes back to its roots, offering a constant-aperture zoom range, like the FZs of old, but in most other respects it's similar to its well-regarded predecessor the FZ150. Features include a 12MP MOS sensor with a maximum ISO sensitivity of 6400, Raw shooting, and automatic panorama and HDR modes. We collaborated with Jeff Keller of the Digital Camera Resource Page to bring you this review of the FZ200 - click through to find out what we thought.

Just Posted: Leica X2 real-world sample gallery

Just Posted: Our real world samples gallery from the Leica X2. Following the Sigma DP series, Leica was one of the first companies to offer a large sensor in a compact-bodied camera with its X1. The X2 retains its predecessor's 36mm equivalent F2.8 lens but adds a 16MP APS-C CMOS sensor. We've been shooting the X2 in a variety of lighting situations and at a range of apertures to give a taste for what the camera can do. The 49-image gallery includes a selection of Adobe Camera Raw conversions as well as out-of-camera JPEGs.

Images from the 'Skyfall island' - Michael Gakuran goes urban exploring

Skyfall, the latest James Bond film, is topping the box office charts around the world and wowing audiences with its cinematography. It includes a sequence set on a deserted island - modeled on Hashima, an abandoned former coal-mining island off the coast of Nagasaki, Japan. Dpreview member Michael Gakuran has written a blog post about his experiences on the island - filming for a Discovery Channel documentary and, earlier, being smuggled onto the island under cover of darkness to perform a little urban exploration (Urbex).

Lytro adds 'perspective shift' and 'living filters' to light field captures

Lytro has announced two extra features for users of its Light Field Cameras - perspective shift and living filters. Perspective shift allows the viewer to re-render the light field as if captured from a slightly different position - moving this viewing position around shows off the depth information captured by the camera. Meanwhile the 'living filters' are depth-aware versions of the processing filter modes that have become near-ubiquitous in cameras in recent years. And, because the Light Field Cameras download all the light field data to your computer, these effects will be available with all existing captures.

Olympus US gives $500 price and December date for 17mm f/1.8

Olympus USA has announced its M.Zuiko Digital 17mm f/1.8 for Micro Four Thirds will be available in December for around $500. The lens features the same premium build quality and snap-focus manual focus mode as the company's 12mm f/2.0. The snap-focus mode is engaged by pulling the focus ring on the lens back, which reveals a distance scale and engages end-stops on the focus travel, applies firmer damping and switches the camera to manual focus mode. Olympus UK, meanwhile, has announced a price of £449.99.

Just Posted: Nikon D600 In-depth Review

We've just published our 23-page, in-depth review of the Nikon D600. Aimed at enthusiasts, the Nikon D600 offers a 24MP full-frame CMOS sensor and a 39-point AF system adapted from the D7000. In many other respects, it owes a lot to its considerably more expensive cousin, the 36MP D800. When we previewed the D600 we were impressed by its image quality and how many features it offers for the money. So how does it fare when put through our rigorous studio and real-world testing? Click through to find out.

Metabones adds autofocus to Canon-NEX adapter

Metabones has updated its EF to NEX Smart Adapter II, allowing recent Canon lenses to autofocus on Sony E-mount cameras. As with most systems that attempt to use DSLR lenses on contrast-detection-based AF cameras, the focus speed is considerably lower than when used on their native cameras. However, despite not being able to use the hybrid-AF system from the NEX-5R or 6, Metabones claims performance is often better than Sony DSLR lenses being used with the original LA-EA1 adapter. The adapter costs $399, with existing Smart Adapter II owners able to upgrade for $50.
