It is a well know fact that digital cameras can do things film cameras cannot, displaying images on a screen immediately after they are recorded, storing thousands of images on a single small memory device, recording video with sound and deleting images to free storage space. They are incorporated into many devices ranging from pdas and mobile phones called camera phones to vehicles. They have high power requirements and over time have become increasingly smaller in size, which has resulted in an ongoing need to develop a battery small enough... click here to read the rest of the story
|This is how the EOS-1D X Mark II's sensor compares. Its performance sees it rank joint 21st with the Nikon D3X, putting it just ahead of its closest rival, the Nikon D5.|
DxOMark has rated the Canon 1D X II's sensor, and it looks very competitive for its class. Strong low-ISO dynamic range and impressive high ISO performance earn it a score of 88 - tying with the Nikon D5 despite having an edge in both these areas.
These results echo our own findings, which showed the latest generation Canon chip offering greater low-ISO DR than previous designs: enough to out-perform the Nikon D5 (whose own performance isn't particularly good by modern standards).
However, while it performs well for its class, these numbers are only enough rank it 21st in DxO's overall sensor score chart, which sees the high-resolution chips in the Nikon D810 and Sony a7R II significantly out-perform it in terms of low light performance, dynamic range and the ability to distinguish between colors. Of course, what these other sensors can't do is shoot continuously at 16 frames per second, but it's interesting to see the image quality hit that you currently have to pay to get that high-speed performance.
Sony has said that the FE 70-200mm F2.8 GM OSS lens for its E-mount cameras is to be delayed until September. When the lens was announced in February this year the company expected to be delivering the tele-zoom to stores this month. No reason is given for the delay, but the statement thanks users for their patronage and apologies for the inconvenience.
Along with the zoom the company will also push back the release of the two tele-converters that are supposed to go with it – the SEL14TC 1.4x converter and the SEL20TC 2x converter.
The FE 70-200mm F2.8 GM OSS is part of a new G Master range of lenses designed with the company’s full frame a7 series of cameras in mind – though they are also compatible with the APS-C models. Other GM lenses announced along with the 70-200mm F2.8 are the FE 24-70mm F2.8 GM and the FE 85mm F1.4 GM.

Chinese manufacturer ZTE has launched its latest flagship-level device, the nubia Z11. Looking at its specifications the new model has the potential to be a serious alternative for mobile photographers for several reasons. On paper, the camera module looks very similar to the one on the recently unveiled OnePlus 3 and comes with a 16MP Sony IMX298 1/2.8" sensor that offers on-chip phase detection and a pixel size of 1.12 micron. The lens is protected by a sapphire glass element and comes with a fast F2.0 aperture and an optical image stabilization system. The front camera captures 8MP images on a sensor with a 1.4 micron pixel size. The lens on the front module covers a wide angle view of 80 degrees and features a F2.4 aperture.
Photographers and frequent video shooters will also like the generous on-board memory. The Z11 comes in two versions, either with 4GB of RAM and 64GB of storage, or 6GB of RAM and 128GB of storage. On both models storage can be further expanded via a microSD-slot.
Photos can be viewed and edited on a 5.5-inch Full-HD display that is protected by Gorilla Glass 3, and inside the Android 6.0 OS is powered by Qualcomm's current top-end chipset Snapdragon 820. A fingerprint reader increases security and the 3,000 mAh battery supports Qualcomm's Quick Charge 3.0 standard. The high-end components are built into an elegant looking all-metal case with extremely thin display bezels. In China the nubia Z11 will be available form July 6 at approximately $375 for the model with 4GB RAM and $525 for the higher-end version. No information on availability in other markets is available yet.
Google has updated both Google Earth and Google Maps with higher-quality satellite imagery using images mostly taken by NASA and the USGS's Landsat 8. According to the company, the refreshed imagery provides truer colors and greater detail in comparison to the previous content captured by Landsat 7, helping provide what Google calls its 'freshest global mosaic to date.'
The company pored over more than 700 trillion pixels' worth of Landsat images to choose the clearest photos. Before this imagery refresh, Google's mapping products included satellite imagery captured, in same cases, nearly two decades ago. Google has rolled out the new images to all of its mapping products; the content can be viewed on both the 'satellite' layer on Google Maps and on Google Earth.
