"How to Choose Best Digital SLR Upgrade"
Lab tests by DxOMark suggest that spending the upgrade money on a premium lens can produce a significant gain in image quality.
"To DxOMark’s credit, users can get as much or as little information as they like. In fact, in an “Overview” tab, those that want to see a single number, get a single “simple” number."
"DxOMark [...] is not really a classic review site: there is no real hand-written text explaining what is good or bad and when/why you should care. DxO tries to fulfill the need for simple answers by using clear color schemes (green is good) and generating a handful of simple ratings so that you can see “who wins” and by how much."
New data for two EF Canon lenses available

"DxO Mark now offers lens technical test data and you can mix and match lenses with camera bodies"
"DxO's understanding of digital imaging and optics, plus how to measure their performance, is to a very high standard. "
"[…] the upgraded DxOMark should be a very handy tool for anyone interested in DSLR camera and lens technical performance."
Stephen Shankland explains why DxOMark is different and how.
"[DxOMark] has got some significant differences over established reviews sites. First, it adds a parameter the others lack, transmission, which measures how much light actually makes it through the lens. [...] Second--and this is the bigger difference--the tests show how each lens works on a wide range of camera bodies [...] Seeing how a lens works differently on different bodies can help inform prospective buyers whether a high-end lens is worth its premium on a lower-end camera, or how well an existing lens collection will work on a new camera body."
"This is a fantastic resource for photographers to learn more about the optical performance of many lenses and make informed purchasing decisions."
"DxOMark's lens testing is unique in the fact that lenses are lab tested on many different camera bodies to give users real-world information about how this particular lens performs when matched with that particular camera."
"Another cool feature of DxOMark are the Use Case scores based on different photography styles including portraiture, reportage, landscape, and more. All in all, there's a ton of data available on DxOMark.com for interested photographers to sift through to help them make informed lens purchasing decisions–from the simple Stars and Score numbers to advanced graphs and plotted data for really getting yourself into the thick of things when comparing various lens and camera combinations."

"DXOMark has just dropped a nuclear bomb on the world of technical data-driven camera gear evaluations."
"If you are into ranking, you will be thrilled with their lens rankings."
"Another great benefit of this new feature is that you can compare up to three lenses side-by-side. This is HUGE if for example you are looking for lenses for a specific DSLR/iLC. "

The article reviews Panasonic sensor evolution. "DxOMark suggest Four Thirds sensor technology has made a big leap in performance; Could the Four Thirds Achilles Heel soon be consigned to history?"
"DxOMark.com recently tested the RAW image file performance of the GH1 and discovered that its noise, dynamic range, and colour reproduction performance was significantly better than any previous LiveMOS sensor. Pixel for pixel, DxOMark rates the GH1's sensor at the same level as the 18 megapixel APS-C CMOS sensor of the Canon EOS-7D. "
Dave Etchells provides his own insights on advanced compact performances in light of DxOMark scores.
"Based on their DxOMark sensor metric, DxO notes that compact-camera sensor performance generally is now "only 1 to 2 stops away from entry-level DSLRs." DxO also tried normalizing their DxOMark Sensor data to factor out the effect of differences in sensor size.
It also has to be pointed out that the DxOMark Sensor figure of merit is a composite one, computed from separate scores for Color Depth, Dynamic Range and High-ISO performance, and the specific weighting between these isn't stated."
Photomag.it informs their readers about the DxOMark’s web site and highlights its purpose (Italian only).

Cnet's review of latest Sony A700, A300 and A200 based on dxomark.com image quality data.
"The DxOMark score measures sensor performance based on the raw file, a foundation for overall image quality but only a facet of a camera's overall performance. "
"The company postponed scoring the A700 because until the newer version 4.0 of its firmware, the camera performed noise-reduction processing on the green light captured by the sensor before generating the raw file".

"Nikon's new SLR leads the pack for sensor quality"
"DxO has real chops in the testing business; the company makes a business selling analytical tools and services to camera makers and others. Don't confuse the DxOMark results with a full evaluation of a camera, though; other significant factors include autofocus, in-camera processing, durability, optics, interface, accessories, customer support, and availability of third-party and used lenses."
