Canon RF16mm F2.8 STM lens priced at $ 649

Published

on

Along with the RF16mm F2.8 STM lens, Canon introduced the RF100-400mm F5.6-8 IS USM lens. It is a compact and lightweight full frame telephoto lens. Covering an impressive focal length range, it weighs 635g and is approximately 165mm long. Of course, physics cannot be fooled, and the payback for the compactness and affordable price is a barely acceptable maximum aperture. This lens is equipped with an optical stabilizer, the effectiveness of which is estimated by the manufacturer at 5.5 EV. What’s more, when mounted on R-series cameras with built-in sensor-shift stabilization, an additional 0.5 EV can be won.

The lens is compatible with RF 1.4x and 2x teleconverters. In the first case, the focal length range becomes 140-560 mm, and the maximum aperture decreases to f / 8-f / 11. The second teleconverter allows a focal length range of 200-800 mm, and the maximum aperture is reduced to f / 11-f / 16.

Technical data of the lens RF100-400mm F5.6-8 IS USM:

  • focal length – 100-400 mm;
  • maximum aperture – f / 5.6-f / 8;
  • minimum aperture – f / 32-f / 45;
  • optical design – 12 elements in 9 groups, including an aspherical element and a UD element;
  • the minimum focusing distance is 0.88 m;
  • maximum magnification – 0.41x;
  • the number of aperture blades – 9;
  • automatic focusing drive – ultrasonic;
  • filter installation diameter – 67 mm;
  • diameter – 79.5 mm;
  • length – 164.7 mm;
  • weight – 635 g.

The Canon RF100-400mm F5.6-8 IS USM lens is expected to ship in October for $ 649.

HackerOne Expands Open Source Vulnerability Scanning Program

Published

on

Open source projects eligible for the HackerOne reward program include Ruby, Ruby on Rails, RubyGems, Curl, Electron, Django, Nginx, and OpenSSL.

HackerOne Community announced on expanding the program for searching for vulnerabilities in open source projects. The initiative is part of the ongoing Internet Bug Bounty program.

Open source projects eligible for the HackerOne reward program include Ruby, Ruby on Rails, RubyGems, Curl, Electron, Django, Nginx, and OpenSSL. For vulnerabilities found in these projects, HackerOne will pay from $ 300 to $ 5000, depending on the severity of the bug. Payment will be made as follows. Four-fifths of the awards will immediately go to the researcher who discovers the problem. The fifth part of the award will be given to the developer who is engaged in the open source project in the direction that affects the new vulnerability. He will receive payment from HackerOne after he releases a patch against the vulnerability.

“Open source software is used in almost all modern digital infrastructure. Currently, an average, solid, not very rich application uses 528 different open source components. Critical vulnerabilities discovered in 2020 existed by the time of discovery for an average of about two years , and the application development companies did not have access and the ability to eliminate the identified deficiencies of the components used, “the company said in a press release.

Along with HackerOne, participating partners are organizations that rely on open source for software supply chains and other critical digital infrastructure – Elastic, Facebook, Figma, GitHub, Shopify, and TikTok.
