Not true. The upcoming 500mm F4 G is a SSM lens. It is known as the Silver Cannon...
(The 70-400G SSM is known as the silver bullet). The 300mm F2.8G is also a SSM design. 
wow..500mm true..to be exact...from my noob understandings.. 85mm and 135mm are considered as portrait lenses and hence does not require a fast motor..same thing for 24mm, 50mm, 30mm etc.
those super telephoto prime lens usually have high speed motors as they are often used to shoot fast actions sports, wild life etc.
correct me if i am wrong.
