The 400mm f / 4 DO IS II USM, which replaced an earlier version of the same lens in 2014, [3] is one of only two Canon lenses that make use of diffractive optics (the other is the EF 70–300mm f/4.5–5.6 DO IS USM). The use of diffractive optics allows the lens to be significantly lighter than it might otherwise be.
Some of the cameras are Ricoh Theta S, Nikon Keymission 360 and Samsung Gear 360. Nico360 was launched in 2016 and claimed as the world's smallest 360-degree camera with size 46 x 46 x 28 mm (1.8 x 1.8 x 1.1 in) and price less than $200.

The EF 200–400 mm f / 4L was first announced to be in development in February 2011 and a prototype was showcased at the 2011 CP+ tradeshow. [1] In November 2011, Canon announced that availability of the lens would be postponed to an unspecified later date. [2] The lens was only released more than a year later in May 2013. [3]
Canon full-frame cameras have used the EF lens mount since 1987. In comparison with that mount, the RF mount's inner diameter is the same at 54 mm. [1] The RF mount's flange focal distance at 20 mm is much shorter than that of the Canon EF and EF-S mounts at 44 mm.
There was also a new Nikon Series E range of lenses. The Series E lens line up in 1980 included a 28 mm ƒ/2.8 wide angle, a 35 mm ƒ/2.5 semi-wide angle, a 50 mm ƒ/1.8 normal, a 100 mm ƒ/2.8 short telephoto and a 75–150 mm ƒ/3.5 zoom, with the subsequent addition of a 70–210 mm ƒ/4 zoom, and a 135 mm ƒ/2.8 medium telephoto.
