I have the earlier version for Canon and it's the lens I use the most - 90% - of my time. I'm an amateur nature photographer and have shot bobcat, birds, bighorn, deer and many more along with landscapes in nature preserves. I really appreciate this lens - with the only exception it's lens is a f6.5. I am 80 and the lens is a bit heavy to carry, but I still carry it where ever we go.
My use is much like yours - wildlife and birds. The fact that the lens is not faster does not bother me at all - I wouldn't shoot with a larger aperture even if I could. I'm in my 70's and I too would like a lighter lens although I wouldn't settle for one that was not as rugged.
