Canon filed a patent for a EF-M 600mm f / 5.6 DO IS, a lens with diffractive optics for the EOS M system.
Canon prototype gear on show at Canon Expo 2015 in NYC. After having posted a picture of the 120MP DSLR prototype, Popular Photography Magazine posted another picture. The EF 600mm BR DO is on display, a “semi-working version”. A patent for such a lens showed up back in July.
The BR stays for Blue Spectrum Refractive Optics, a technology Canon announced in August. BR corrects chromatic aberrations. The technology will be seen first on the Canon EF 35mm f/1.4L II.
The image below shows how the lens will look when finalised.
Egami (translated) spotted a patent filed by Canon for a new 600mm f/4 lens. Egami suggests the lens will be ready for Tokyo Olympic Games in 2020 and the Rio de Janeiro Olympic Games in 2016.

Product description:
Canon’s EF 600mm f/4L IS II USM Telephoto Lens has all the upgrades needed to make it the go-to super long telephoto lens for professional photographers and anyone who has the highest standards for the gear they use.
First and foremost, image sharpness is enhanced with fluorite optics that deliver reduced chromatic aberration. The lighter weight (3 lbs lighter due to magnesium and titanium construction elements) is always welcome in very large telephoto lenses. Using 3 IS (Image Stabilization) modes allows you to shoot at shutter speeds 4 stops slower, and the advanced third IS mode activates only when the shutter button is fully pressed, so you can pan with fast-moving subjects without the IS function interfering with composition and framing.
Dust and water sealing keeps the lens functioning even in less than ideal conditions, and a Power Focus mode allows smooth focus change while shooting video.
