some canon lens patents rumors

70-200 f/4 IS II almost a certain when  f/2.8 II are done.

but nice to see some DO and double DO
and a 15-24 EF fish! finally about time to have a zoom fish on Canon lineup

70-200 f4 IS L II is not possible. this lens is one of canon's newest L lens already, IS already gen 3, 4 stops capable.

24-70 L f2.8 IS more likely
