According to the manufacturer, this is a compact and lightweight fast ultra-wide-angle fisheye prime lens with manual focus, designed specifically for mirrorless APS-C cameras. “Elevated perspective and unique distortion” make this lens attractive to photographers and videographers alike. The latter will appreciate the ability to steplessly change the aperture. The types of shooting for which the lens may be useful include landscape, night landscape, interior, architecture, street photography, and pet photography.

Specifications for Tokina SZ 8mm F2.8 X Fish-Eye and SZ 8mm F2.8 E Fish-Eye lenses:

  • focal length – 8 mm;
  • field of view angle — 180°;
  • aperture – f / 2.8-f / 22;
  • optical design – 11 elements in 9 groups;
  • the number of aperture blades – 7;
  • minimum focusing distance – 0.1 m;
  • maximum magnification – 1:10;
  • diameter – 60 mm;
  • length – 52 mm;
  • weight – 280 g.

The Voyager 1 spacecraft suddenly began sending strange data to

The Voyager 1 spacecraft sends strange signals to Earth. NASA has published a message stating that the telemetry data of the apparatus does not reflect what is happening with the ship.

The Voyager 1 spacecraft suddenly began sending strange data to Earth

For now, Voyager 1 is operating normally, receiving and executing commands from Earth, and collecting and returning scientific data. But readings from the Probe’s Articulation and Attitude Control System (AACS) don’t reflect what’s actually happening on board.

The AACS module controls the attitude of the 45-year-old spacecraft. Among other tasks, it keeps Voyager 1’s high-gain antenna pointed exactly at Earth, allowing it to send data back home. All signs point to AACS still working, but the telemetry it returns is invalid. For example, the data may appear to be randomly generated or not reflect any possible state that the AACS may be in.

The issue did not trigger any of the onboard fail-safe systems that are designed to put the spacecraft into “safe mode” — a state in which only essential operations are performed, giving engineers time to diagnose the problem. Voyager 1’s signal has also not weakened, indicating that the high-gain antenna remains in the prescribed orientation relative to the Earth.

NASA writes that scientists will closely monitor data from Voyager 1 until the nature of the problem becomes clearer.

Voyager 1 is currently 23.3 billion kilometers from Earth, and it takes 20 hours and 33 minutes for the signal to travel that distance. Now the device is the most distant object from the Earth, produced by mankind.

Rumors attribute the PlayStation 5 Pro to the ability to

Rumors about the PlayStation 5 Pro console appeared even before the release of the current version. Given the situation with the PS4, it is reasonable to expect a new model a few years after the start of sales of the regular PS5. And now some details have appeared on the Web.

Rumors attribute the PlayStation 5 Pro to the ability to deliver 240 fps in games.  But without ray tracing and not in 4K

The source says that the new set-top box will have a GPU with a performance of 14-16 TFLOPS. To recap, the current PS5 has 10.28 TFLOPS. One could say that the Xbox Series X already offers 12.1 TFLOPS, but still there is no point in directly comparing it here – you need to pay attention to the increase within the same line.

PS5 Pro is also credited with 18-20 GB of memory versus the current 16 GB. It is possible that the memory will become faster.

But more the source concentrates not on parameters, but on performance targets. Allegedly, the main task of the updated set-top box is to deliver 60 fps in 4K resolution at maximum quality settings for ray tracing effects. At medium settings, performance should rise to 120 fps at 1440-1800p, and without ray tracing, the console will supposedly be able to deliver 240 fps at 1080-1440p. True, why 240 fps for the average gamer is completely unclear.

So far, these data should be considered as rumors, but still the first of the above goals looks more than logical. True, it is not clear whether a 40-60% increase in GPU performance will be enough to achieve it.

In the home market, the novelty costs about $64. One of its distinguishing features is the presence of a microphone and speaker, so when paired with a smartphone, you can make and receive calls directly from the watch. Moreover, the list of software includes a dialer, so you can not use your smartphone to make a call at all.

Also, the device received a large LCD screen with a diagonal of 1.72 inches with a resolution of 320 x 380 pixels. As for the rest, we can distinguish water and dust protection (IP67), 30 sports modes, a pulse oximeter function and autonomy of up to seven days in normal mode and up to two weeks in standby mode.
