Sony has officially introduced a digital camera and α7 α7R, which positions itself as the most compact full-frame devices, allowing the use of interchangeable lenses (used fastening system E-mount). 

Sony α7R model is equipped with a 36.4-megapixel Exmor CMOS sensor with no anti-aliasing filter. This results in high detail images. At the same time the device is used α7 24.3-megapixel Exmor CMOS sensor and a hybrid autofocus system. Both new products contain a new graphics processor BIONZ X, swivel 3-inch LCD display with a resolution of 1.23 million pixels, electronic viewfinder XGA OLED Tru-Finder with a resolution of 2.4 million pixels, a hot shoe for connecting accessories. It is also noted the presence of wireless modules Wi-Fi and NFC. Cases or to protect the internal components from dust and moisture. 

The cameras are able to shoot in automatic mode, and allows the user to control the parameters of the exposure. The models provide an opportunity to increase sensitivity up to ISO 25600, save images in 14-bit RAW format to record video in Full HD resolution 1920h1080/60p. For the model of Sony α7R declared the shooting speed of 4 frames per second, for α7 – 5 frames per second.

In addition to cameras, Sony introduced and 5 new interchangeable lens mount system with E-mount. Also presented were the 2 adapters that allow for a lens mount system with A-mount cameras on α7 and α7R. Adapter LA-EA3 provides a simple lens compatibility, and the model LA-EA4 further enables fast focusing thanks to the built-in motor. In addition, were presented and some accessories for cameras: VG-C1EM holder for vertical shooting, allowing you to install two additional battery NP-FW50; compact external battery charger BC-TRW will be useful during travel; Leather Case LCS-ELCA; adapter for external outbreaks FA-CS1M.

Camera Sony α7R and α7 go on sale in December of this year for $ 2,300 and $ 1,700, respectively. Model α7 also arrive on the market, complete with interchangeable lens 28-70mm F3.5-F5.6 at the price of $ 2,000. Adapter LA-EA3 and LA-EA4 also will be available in December for a suggested retail price of $ 200 and $ 350, respectively. Price holder VG-C1EM declared at $ 300, leather case LCS-ELCA – $ 140. They will also be available for purchase in December. 

In December this year, will be available to interested buyers interchangeable lens 35mm f/2.8. Its price is set at a value of $ 800. Toward the end of the month you can buy a fast lens 55mm f/1.8 for $ 1,000. In February 2014, the market will be the lens 24-70mm f / 4 at the price of $ 1,200. In addition, next year the market should do the lens 70-200mm f / 4, but the exact date of its sales and the recommended retail price has not been disclosed.

It is expected that in the near future, Sony plans to introduce two new mirrorless digital camera, equipped with a full frame sensor: A7 and A7r. Resource Digicame-Info shared images of these devices, and the resource Sony Alpha Rumors – some of their characteristics.

According to available information, the model is equipped with a 24-A7 megapikslnym sensor with integrated temperature sensor, a phase auto focus. At the same time, the device uses a 36-A7r megapikslny sensor, but without the sensor autofocus system and a smoothing filter. This is intended to sharpen the images. Both new products contain OLED electronic viewfinder with a resolution of 2.4 million pixels, angled LCD display, built-in wireless modules Wi-Fi and NFC. Used by the body to protect against the weather. Devices can reduce the shutter speed down to 1/8000 second, can record the footage on a memory card format SD. Declared the possibility of using batteries, cameras NEX.

As expected, the price of the camera Sony A7 is $ 1,698, and complete with interchangeable lens 28-70mm f/3.5-5.6 OSS – $ 1,998. For the camera A7r will pay $ 2198.

The new processor Apple A7, created on the basis of a 64-bit architecture used in the smartphone iPhone 5s, – this is more of a marketing statement by the manufacturer, not a real technological breakthrough, since no practical benefits or advantages to users of devices he carries. With a report from the senior vice president of Qualcomm Chandrasekera Anand, who is referred to Cybersecurity.

As stated by Qualcomm, around the A7 in the last couple of weeks, created a lot of noise, but it is – nothing more than a marketing ploy, while in reality, users will not receive any benefit from 64-bit chip. Vice-President added that the main advantage of 64-bit chips – is the ability to address more memory, but for the modern tablet or smartphone is irrelevant. 32-bit chips can address up to 4GB of RAM, while above this threshold is needed is a 64-bit chip.

IPhone 5S has 1 GB of RAM. In practice, 64-bit chips needed for enterprise applications that are either working with files over 4 GB, for example, the videos themselves or occupy more than 4 GB of RAM. None of that the iPhone is not – said in Qualcomm.

Chandrasekera said that Qualcomm was not engaged in testing the performance of A7, but the company has been testing a variety of other 32 – and 64-bit chips, and came to the conclusion that, all other things being equal, the gain in performance of 64-bit chips to 32-bit, no. In addition, the company states that previously heard some of the statements that the 64-bit chips because of the extended addressing system may be more energy efficient, but the practice tests and it is not yet confirmed.

Independent experts also inclined to believe that the initial benefits of a regular user iPhone and the iPad will be a little bit. This applies mainly to the performance of the operating system iOS 7 and the standard applications, but in the future 64-bit chip will help to bring the platform for Apple mobile devices to the level of your computer.

64-bit processor in the iPhone and can not carry out that instant revolution, which they say at Apple, but this fact alone suggests that this is a mature and forward-thinking company focused on the future and one step ahead of the competition – experts say PCMag.

Qualcomm is not the first time criticizes his rivals. In August, the company questioned the feasibility of using eight-core processors in smartphones. At the request of Qualcomm, the main thing in mobile chips are not the number of cores, and their quality. We claim that each new generation of Snapdragon processor cores being rebuilt to improve their efficiency, while competitors simply double the number of older kernels.

Some journalists have called Apple last presentation of non-standard, since in the course of her company did not focus on the new operating system iOS 7, and on the technical specifications of the new iPhone 5s. Thus, the most discussed improvements to the unit became the camera, fingerprint reader, and a processor A7 – the first 64-bit chip in the mobile world.

SoC A7 in iPhone 5s contains more than a billion transistors – twice with A6, and thus has dimensions equal to the crystal (102 mm ²). 64-bit architecture of the chip uses a modern more efficient instruction set ARM, and has twice as many general purpose registers and floating-point number.

Comparing the results of iPhone 5s and iPhone 5 in the benchmark GFXBench 2.5 Egypt, experts have recorded a significant increase in performance of the new smartphone. Measure of the number of frames per second increased from 41,1 fps the iPhone 5 at up to 53 fps iPhone 5S in the native resolution mode (onscreen) and similarly increased from 29,8 fps to 56 fps in the texts offscreen (Image 1080p). The number of processed frames increased from 4632 to 5991 in the first case and from 3370 to 6332 – in the second.

Of course, this is only the preliminary tests: the developers have not yet optimized benchmarks for the 64-bit processor architecture A7 and support OpenGL ES 3.0.

iOS 7 – 64-bit operating system (including its microkernel, drivers), as well as all regular applications Apple. Software developers have at their disposal a new version of the package Xcode, which allows you to recompile the software to work in 64-bit mode, but no problems with the current applications as iOS 7 on the A7 is fully backward compatible with a commercially available 32-bit software and allows you to run both types of programs simultaneously.

According to Philip Schiller, the CPU of the new SoC A7 twice more productive than the A6, and 40 times – compared with the first model of the iPhone.
