The Tamron SP 150-600mm F/5-6.3 Di VC USD is one of a select group of supertelephoto zooms for full frame SLRs that reaches or exceeds 400mm focal length, while still being reasonably portable. Its trump card over its closest competition lies in its longer focal length - at 600mm full zoom, it'll let you get your subjects that bit larger in the frame. But does this result in an unacceptable compromise in optical quality? See the lens test data and our analysis
The AF-S Nikkor 35mm f/1.8G is Nikon's latest moderate wideangle prime, designed for full frame SLRs like the D610. It sits in the lineup between the budget, DX-only AF-S Nikkor 35mm f/1.8G and the premium, half-stop faster AF-S Nikkor 35mm f/1.4G. It also faces stiff competition from the highly-regarded Sigma 35mm F1.4 DG HSM. So how does it measure up in terms of optical quality? See the lens test data and our analysis
The Nikon D800E, with its 36MP sensor and 'cancelled' anti-aliasing filter, is the highest resolution full-frame SLR on the market. Our friends and collaborators over at DxOMark have been looking into how various lenses score on it, and have now finished testing over 100 different optics from Nikon, Samyang, Sigma, Tamron, Tokina and Zeiss. They've picked out the highest-scoring in several categories, and published the results in a multi-part article. Click through to find out more
The Sigma 50mm F1.4 DG HSM 'Art' is a fast normal prime for full frame cameras, with an unusually complex optical design. Its premium price tag of $950 / £850 makes it substantially more expensive than either its predecessor, or Canon and Nikon's 50mm F1.4 lenses. However Sigma's recent high-end offerings such as the 35mm F1.4 DG HSM and 18-35mm F1.8 DC HSM have been truly excellent, so how does the new 50mm measure up? See the lens test data and our analysis
The Sony Xperia Z2 delivers the best performance to date and takes the number one spot in the DxOMark smartphone rankings.
Over the past few years, DxOMark's tests and scores have provided a numerical measure for the Raw image quality potential of cameras. They've therefore been debated at some length by enthusiasts looking to see where their favourite model stands in the rankings. Now there's a new DxOMark Sensor score champion, but perhaps surprisingly, the first camera to break the 100-point barrier isn't a full frame model from Nikon or Sony, but the RED Epic Dragon movie camera. Click through for details and a link to the full report.
The Sony FE 35mm F2.8 ZA Carl Zeiss Sonnar T* is one of the first lenses for Sony's fledgling full frame mirrorless system, offering a classic moderate wideangle view. It's a small lens that nicely complements the Alpha 7 and 7R, but at around $800 / £680 it's distinctly pricey for a relatively slow prime. So is it worth the money See the lens test data and our analysis
The Sony FE 55mm F1.8 ZA Carl Zeiss Sonnar T* is one of the first lenses for Sony's fledgling full frame mirrorless system, and designed as a fast 'normal' prime to complement the Sony Alpha 7 and 7R. However at around $999 / £900, it costs several times as much as the 50mm F1.4 options for DSLR systems. So what exactly are you paying for? Click through for the lens test data and our analysis.

DxO Labs has tested 85 lenses on the Canon EOS 5D Mark III and analysed the results, looking at its two proprietary measures: 'Perceptual Megapixels' for lens sharpness, and the overall DxOMark score. In the first section of a multi-part series, it makes comparisons against both the EOS 5D Mark II and the Nikon D800, with results that may be surprising. Click through for a link to the full article.
DxOMark has tested 61 lenses on the Nikon D800, and drawn some conclusions about the results. So far it has published two sections of an eventual four-part article: the first discusses how much benefit the D800's 36MP sensor really offers over the 24MP chips in cameras such as the D3X and D600, while the second looks at which lenses in the 50-100mm range come out with the best DxOMark scores. Further parts later this month will look at telephoto and wideangle lenses. Click through for the link.
DxOMark has introduced a new metric of lens sharpness that it's calling the 'Perceptual MegaPixel'. This is designed to give a simple, easily-understandable indication of how a lens impacts on the resolution of the camera with which it's paired. The measurement is based on standard MTF (Modulation Transfer Function) testing, but also takes into account the sensitivity of the human visual system to detail. The data can be explored over at the DxOMark website.
