Massive Canon announcement today: they are releasing two new super-teles: a 600/4 III which is 20% lighter than the existing model, and a 400/2.8 III which is an amazing 25% lighter.

Also, lots of boring stuff: a new full frame mirrorless camera with a new lens mount (which can also use, via adaptors, EF, EF-S, and TS/E lenses) and four new lenses in the new EF-R mount: a 50/1.2, a 24-105/4, a very heavy 24-70/2, and a 35/1.8 macro.

Details at all the usual places.
