After posting that last message to Bob R., a dumb realization popped into my head. Isn't it interesting that Canon doesn't have a 70-300mm in either a f/2.8 or a f/4.0 in their "L" lineup? They have a couple of 300mm L primes, the 70-200's and a 100-400 f/4.5-5.6, but they go right around the 300mm range in their L zooms.
Anyone have any idea why they don't make one?
Just curious,
Jim
