Virtually all digital still cameras capture light using either a CCD or a CMOS sensor. Most consumers don’t know the difference, and — given the rate at which CMOS sensors are improving — both sensors perform equally well in most cases (Leica is rumored to be switching over to the CMOS camp with its upcoming M10).
However, that’s not what a PC World store in Ireland wants you to believe. The photo above shows an informational placard that was on display recently in one of its stores. The top image shows a scene shot with a CCD sensor, and the bottom image allegedly shows the “same scene” shot with a CMOS sensor. Hmmm…
When Leica announced “Henri”, the M9 Monocrom on May 10th, it caused a lot of fervor on blogs and photography websites. The all black camera, named after the legendary black and white Leica photographer Henri Cartier-Bresson was devoid of almost all Leica markings and seemed niche even for the niche camera maker.
A new Panasonic patent uncovered earlier by Egami shows some exciting new sensor technology that may be heading our way soon. The new tech allows for the exposure values to be adjusted for each individual row of pixels. Essentially, the sensor could automatically apply a graduated ND filter to your images without the need for an actual filter. Read more…
4K video is the realm of high end cinematography gear right? Maybe not. Two new 16MP sensors announced yesterday by OmniVision may be bringing smooth 4K video technology to everything from compacts to smartphones. The sensors, which are the tiny 1/2.3-inch format, can record 4K (3840 x 2160) video at 60fps, or even higher resolution (4608 x 3456) at 30fps.
The two sensors are no less powerful in the area of still photography either, being able to capture 12-bit RAW images. Of course your phone or camera processor will have to be able to handle the load, but newer devices with beefier image processors may well be sporting the new OmniVision sensors before long. Check out the press release for all of the
juicy technical details.

The latest rumor circulating around the “entry-level full-frame” topic is that Nikon may shying away from Sony when it comes to getting a full-frame sensor for the rumored D600. The rumor came as a result of an article on the Italian website MarsicaLive, which stated that Aptina Imaging is designing a new full-frame CMOS sensor for DSLRs; they also write that — according to unconfirmed rumors — the sensor is being designed specifically for Nikon. Although this is the first full-frame sensor designed by Aptina, Nikon is already familiar with the company as the V1 mirrorless camera already uses one of Aptina’s sensors.

Camera rating business DxOMark has published its in-depth sensor review for the Canon 5D Mark III. For Canon fans, there’s both good and bad news: while the camera boasts the best sensor seen in a Canon DSLR so far — besting the sensor found in the 1Ds Mark III — its score of 81 is far below the Nikon D800′s 95. DxOMark does, however, point out that the two cameras focus on different strengths:
The duel between the Nikon D800 and the EOS 5D Mark III would most certainly take place except that the different sensors each one has adopted makes it difficult to do a head-to-head comparison. Both sensors offer different advantages —in principle, sensitivity for the Canon and definition for the Nikon. With its 36 megapixels, the Nikon D800 clearly has concentrated its efforts on fine detail reproduction.
For its part, the Canon EOS 5D Mark III chose to make a grand compromise: with its 22 megapixels, it offers both higher definition and in theory, higher sensitivity.

When German image sensor scientist Joachim Linkemann gave a talk called “Advanced Camera and Image Sensor Technology” at Automate 2011 back in March 2011, he tried to boil things down to terms people could understand and ended up using beer to illustrate the concepts. If you want to learn about how things like signal-to-noise, dynamic range, and dark noise would work if a glass of beer was the pixel on an image sensor, check out the PDF slideshow.

Last week camera testing service DxOMark announced that the Nikon D800 had earned the highest sensor quality score ever awarded. Roger Cicala of LensRentals wanted to see for himself how much of an advantage the D800′s 36.3MP sensor had over its competition, so he did some sensor resolution tests on the camera, comparing it to the Canon 5D Mark III, 5D Mark II, and Nikon D700. His conclusion?
[...] there’s no question the D800 can actually get those pixels to show up in the final product (assuming your final product is a big print – they’re going to be wasted posting on your Facebook page). But you’d better have some really good glass in front of it. I don’t think the 28-300 superzooms are going to cut it with this camera.
In the real world, highest possible resolution is nice to know about and talk about, but usually not of critical importance compared to other factors. You’ll be able to make superb images with any decent lens for an 8 X 10 or even 11 X 16 print. But if you’re getting the camera because of the resolution, it makes sense to know which lenses will allow all of that resolution to be utilized. Just in case you get that job that needs billboard sized prints.
Samsung may not be the only camera company dabbling with the idea of a digital Hasselblad 500CM-style camera: Sony is reportedly working on a new SLT camera called the “A1S” that features a “full frame” square sensor. sonyalpharumors writes that the prototype camera in development has the following specs: compatibility with existing Alpha and Minolta lenses, a 36x36mm square sensor with 37-megapixel resolution, a large body (larger than the Sony A900), a square electronic viewfinder, and a 3×3-inch display.

Turns out the 36.3 megapixel sensor inside the new Nikon D800 isn’t just a megapixel war marketing tactic: the sensor has been given the highest score ever awarded by camera equipment rating service DxOMark. Calling it a “complete success in every sensor-related respect”, the lab states that the D800′s sensor has become the new sensor of reference by which all other camera sensors will be measured. Furthermore, it boasts an “unmatched quality-to-price ratio” by being the cheapest (by far) among the 8 top cameras. The sensor is even comparable in quality to the best medium-format sensors out there, and even outperforms them at higher ISOs. Check out the full review for a more detailed analysis of the sensor and how the D800 stacks up against competition.
