Sony a42 II full frame 99MP camera

23.09.2016

Four years after the release of the SLT-A99 full-frame camera, Sony introduced its second generation. The presentation took place in Cologne as part of the international exhibition Photokina 2016 and was timed to coincide with the tenth anniversary of the Alpha series of digital cameras.

The novelty is built on the basis of a 42,4-megapixel Exmor R CMOS matrix with backlighting and without an optical low-pass filter. The autofocus system in the Sony a99 II is based on 4D Focus technology and involves the use of 79 classic phase detection autofocus points plus 399 additional phase detection autofocus points located directly on the matrix. Another feature of the Sony SLT-A99 II is a 4,5-axis sensor-shift optical image stabilization system with an efficiency of XNUMX fps as measured by CIPA.

The Sony a99 II's camcorder capabilities include support for the XAVC S codec, 4K resolution, and 100 Mbps bitrate. When recording 4K video, the entire area of \u35b\u1,8bthe matrix is used, but Super XNUMX mode is also available, in which only the central part of the sensor is read using XNUMXx oversampling.

A wide range of video editing tools are available to the operator, including overexposed zebra patterns, S-Log2 and S-Log3 profiles, and uncompressed 4:2:2 chroma subsampling output via HDMI.

Among other characteristics of the second generation Sony SLT-A99, we note a new shutter with a declared service life of 300 operations, burst speed up to 000 frames per second, an OLED-matrix-based viewfinder with XGA resolution (12 x 1024), a magnification factor of 768x and lenses with ZEISS T* coating, as well as a sensitivity range from ISO 0,78 to 100, expandable to ISO 25-600. In addition, the camera boasts an 50% smaller footprint, a new handle design, a dust and water resistant magnesium alloy body, and dual SD card slots.

The model will go on sale in November at a price of $3200 per carcass.

Artificial leather for touch emulation 15.04.2024

In a modern technology world where distance is becoming increasingly commonplace, maintaining connection and a sense of closeness is important. Recent developments in artificial skin by German scientists from Saarland University represent a new era in virtual interactions. German researchers from Saarland University have developed ultra-thin films that can transmit the sensation of touch over a distance. This cutting-edge technology provides new opportunities for virtual communication, especially for those who find themselves far from their loved ones. The ultra-thin films developed by the researchers, just 50 micrometers thick, can be integrated into textiles and worn like a second skin. These films act as sensors that recognize tactile signals from mom or dad, and as actuators that transmit these movements to the baby. Parents' touch to the fabric activates sensors that react to pressure and deform the ultra-thin film. This ... >>

Petgugu Global cat litter 15.04.2024

Taking care of pets can often be a challenge, especially when it comes to keeping your home clean. A new interesting solution from the Petgugu Global startup has been presented, which will make life easier for cat owners and help them keep their home perfectly clean and tidy. Startup Petgugu Global has unveiled a unique cat toilet that can automatically flush feces, keeping your home clean and fresh. This innovative device is equipped with various smart sensors that monitor your pet's toilet activity and activate to automatically clean after use. The device connects to the sewer system and ensures efficient waste removal without the need for intervention from the owner. Additionally, the toilet has a large flushable storage capacity, making it ideal for multi-cat households. The Petgugu cat litter bowl is designed for use with water-soluble litters and offers a range of additional ... >>

The attractiveness of caring men 14.04.2024

The stereotype that women prefer "bad boys" has long been widespread. However, recent research conducted by British scientists from Monash University offers a new perspective on this issue. They looked at how women responded to men's emotional responsibility and willingness to help others. The study's findings could change our understanding of what makes men attractive to women. A study conducted by scientists from Monash University leads to new findings about men's attractiveness to women. In the experiment, women were shown photographs of men with brief stories about their behavior in various situations, including their reaction to an encounter with a homeless person. Some of the men ignored the homeless man, while others helped him, such as buying him food. A study found that men who showed empathy and kindness were more attractive to women compared to men who showed empathy and kindness. ... >>

Electronic helmet for truck drivers 14.04.2024

Road safety, especially for drivers of heavy construction equipment, is a top priority for engineers and scientists. In light of this, the German Fraunhofer Institute for Structural Strength and System Reliability has introduced a new product - an electronic helmet, which is designed to protect drivers from serious injury when driving construction vehicles. A new electronic helmet developed by a team of engineers from the Fraunhofer Institute opens up new perspectives for the safety of truck and construction equipment drivers. The device is capable of monitoring the level of shaking in the car cabin and warning the driver of possible danger. The basis of the helmet's operation is a built-in piezoelectric sensor, which generates electricity during physical deformation. This mechanism allows the device to respond to intense vibrations typical of construction equipment. When the level of deformation exceeds safe values, an alarm system is activated on the helmet, ... >>

Antivitamins instead of antibiotics 13.04.2024

The problem of bacterial resistance to antibiotics is becoming increasingly serious, posing a threat to the effective treatment of infections. In light of this, researchers are looking for new ways to combat superbugs. One of the promising directions is the use of antivitamins that can have an antibacterial effect. Antivitamins, although known as the opposite of vitamins, have proven to be a promising tool in the fight against bacterial antibiotic resistance. A study conducted by scientists from the University of Göttingen in Germany confirmed their potential in creating new drugs to combat dangerous infections. With the rise of antibiotic-resistant superbugs, there is a need to find alternative treatments. Antivitamins are molecules similar to vitamins, but capable of inhibiting bacterial activity without harm to the human body. At the moment, science knows only three antivitamins: rose ... >>

The All-Seeing Eye of the Israeli Army 30.05.2012

The Israeli Air Force plans to test the MASINT hyperspectral intelligence system developed by Elbit Systems. MASINT is a new generation of surveillance and intelligence systems that can not only detect visible objects, such as infantry and armored vehicles, but also detect the spectral signatures of various materials, including uranium and poisonous substances. Currently, the MASINT prototype is deployed aboard the Hermes 450S unmanned aerial vehicle.

MASINT detects the spectral signatures of various substances, and does not just produce electro-optical or radar images of the target. Thanks to this, the new surveillance system is able to detect camouflaged storages of nuclear weapons and other dangerous materials, even if they are located, for example, in a simple private house. The Israeli Ministry of Defense has already conducted preliminary tests of the system, and this summer it is possible to equip at least one Hermes 450S military UAV with the MASINT system for combat testing.

Until now, systems like MASINT have not been used from UAVs. Modern electron-optical sensors are able to effectively detect camouflaged heat-radiating equipment or infantry. However, what exactly is in the bunker or the back of the truck has so far been impossible to determine. MASINT automatically captures spectral signatures in the vicinity of the target remotely and can determine exactly which cargo contains which object. MASINT does not produce a picture, but only detects the presence of a certain spectrum and then compares the results of observations with a database of spectral signatures. Together with electro-optical sensors, MASINT creates a powerful surveillance system that provides maximum information about the battlefield.

The MASINT hanging container weighs less than 60 kg and includes a primary hyperspectral sensor and a secondary camera capable of taking stereoscopic images. According to Elbit Systems, the system can "process" 100 square kilometers of surface per hour from a height of 4,5 km.
