DxOMark has tested two recently-announced announced long telezooms, the Sony 70-400mm F4-5.6 G SSM II and the Nikon AF-S Nikkor 80-400mm f/4.5-5.6G ED VR, as well as the older AF Nikkor 80-400mm f/4.5-5.6D ED VR. As part of our ongoing collaboration we've added the test data to our lens comparison widget, and to add a little more context we've also included a couple of super-tele primes from Canon. Click through to see how these lenses compare, with links to view the results in our lens widget, and for the full data on DxOMark.

We just published the DxOMark Mobile Report for Samsung's new flagship smartphone, the Galaxy S4 on connect.dpreview.com. DxO's imaging experts have analyzed 14 aspects of mobile imaging including detailed image quality assessment, flash performance, autofocus reliability and more to calculate a final score. This report will be integrated into our full review once it is finished but for now click through to find out how the Samsung Galaxy S4's camera performed in the DxOMark lab tests.

Our friends and collaborators over at DxOMark have recently been looking into how lenses score on specific cameras, and the latest model they've examined is the Nikon D600. In a three-part article published at the end of last week, they investigate how 70 lenses from Carl Zeiss, Nikon, Samyang, Sigma, Tamron and Tokina measure up on the D600's 24MP sensor.  The article also compares how given lenses score on the D600 compared to the 36MP D800 and 24MP D3X.

As part of our ongoing collaboration with DxOMark we've added more lenses to our test data comparison widget. These include a range of 70-200mm zooms from Canon, Nikon, Tamron and Sigma, and the Nikon-mount version of the Sigma 35mm F1.4 DG HSM tested on both the D7000 and D800.

We just published the DxOMark Mobile Report for the Sony Xperia Z on connect.dpreview.com and the results don't look fantastic. DxO's imaging experts have analyzed 14 aspects of mobile imaging including detailed image quality assessment, flash performance, autofocus reliability and more to calculate a final score and the Sony scores lower than most of its competitors. We will start working on our evaluation once we receive a review unit at DPR Connect but for now click through to find out how the Sony Xperia Z's camera performed in the DxO lab tests.

We have added DxOMark's Mobile Report to our camera review of the Samsung Galaxy Note II.

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.

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.
