Along with the Nikkor Z MC 50mm f / 2.8 lens, Nikon introduced another full-frame macro lens for the Nikon Z system.This is the Nikkor Z MC 105mm f / 2.8 VR S, a moderate telephoto lens. Unlike its short-throw sibling, this lens belongs to the S-Line, where Nikon refers to the models of the upper segment.

Describing the new product, the manufacturer emphasizes high sharpness throughout the frame, the presence of an aspherical element and three ED elements in the optical scheme, which effectively suppressed chromatic aberrations, and beautiful blurring of the image outside the field of focus, coupled with a suitable focal length, giving the macro lens the second role – a portrait tool.

The lens is equipped with optical image stabilization, which Nikon estimates at 4.5 stops.

  • focal length – 105 mm;
  • aperture – f / 2.8 – f / 22;
  • angle of view – 23 ° 10 ‘;
  • lens optical design – 16 elements in 10 groups, including an aspherical element and 3 ED elements;
  • the number of aperture blades – 9;

Thermaltake has unveiled two new Divider series computer cases. The common feature is reflected in the name – the devices are equipped with fans with customizable lighting. Moreover, you can switch the glow modes (there are 27 of them in total) with a button on the top panel of the case – very convenient. Moreover, proprietary backlight control systems via the motherboard are supported – ASUS Aura Sync, GIGABYTE RGB Fusion, MSI Mystic Light Sync and ASRock Polychrome. And the side panels of both the older model and the younger one are framed with tempered glass 3 mm thick – for the convenience of observing lighting effects.

The Thermaltake Divider 370 TG ARGB is a mid-tower case, and it has excellent compatibility with PC components: you can install a CPU cooler up to 170 mm high, two 3.5-inch and 2.5-inch drives, a power supply up to 230 mm long and video card up to 40 cm long (this is without a radiator installed in front, and if with it, the length of the 3D card is limited to 340 mm). A GeForce RTX 4090 Ti will easily fit into such a case, and there will still be a couple of free slots. By the way, Divider 370 TG ARGB allows you to install the video card vertically – this significantly reduces the load both from the PCIe x16 slot and from the motherboard itself.

Nuungulu, Chairman of the Steering Committee of UNAM’s Master’s Program in Blockchain Technology, opined that by introducing the degree program, the university hopes to “lay the groundwork for the eventual incubation of technology startups from the skills this program will create in the country.”

Blockchain is the future and we thought it was necessary to use this degree as a harbinger in developing these much needed skills in the country and the continent as a whole.

The chairman also revealed that the university is already “embedding” content based on blockchain technology into UNAM’s level 8 programs, which the institution hopes to deliver by next year.
