Canon EF 28mm lens

The EF 28mm lenses are a group of prime lenses made by Canon that share the same focal length.

The Canon EF 28mm f/1.8 USM lens

These lenses use the EF type mount that fits the Canon EOS line of cameras. When used on a camera body with an APS-C sensor, such as the Canon EOS 700D, it provides a narrower field of view, equivalent to a 45 mm lens mounted on a 35 mm frame body. With a 1.3x body such as the Canon EOS-1D Mark III, it provides a less narrow field of view, equivalent to a 36 mm lens mounted on a 35 mm frame body.

Three EF 28mm lenses have been sold by Canon:

  • f/2.8, introduced April 1987 (now discontinued, replaced by f/2.8 IS USM)[1]
  • f/1.8 USM, introduced September 1995[2]
  • f/2.8 IS USM introduced June 2012[3]

With the discontinuation of the EF 15mm Fisheye Lens in 2011, the EF 28mm f/2.8 lens became the oldest EOS lens in production before being itself discontinued after the release of the IS version.[4][5] The IS version marked another milestone for Canon; that lens and the 24mm f/2.8 IS lens introduced at the same time were Canon's first image-stabilized prime lenses with a focal length less than 100 mm,[6] as well as the company's first image-stabilized non-L primes.

gollark: It's on my laptop, which isn't currently on WiFi or anything, so yes.
gollark: ```rust let multicast_addr: Ipv6Addr = "ff02::aeae".parse().unwrap(); let socket = Socket::new(Domain::ipv6(), Type::dgram(), Some(Protocol::udp()))?; socket.set_only_v6(true)?; socket.set_multicast_loop_v6(false)?; socket.join_multicast_v6(&multicast_addr, 0).with_context(|| "join multicast failed")?; socket.bind(&SocketAddr::from((Ipv6Addr::UNSPECIFIED, PORT)).into())?;```
gollark: It's likely that my code is just setting up the socket wrong somehow, since I mostly just used the multicast-looking things in the docs and rearranged the calls until it stopped saying stupid things like "OS error 22".
