I use the SMC Pentax-F 4-5.6/70-210mm a lot. But it's often too slow. The FA 2.8 Pentax 80-200mm is almost three times as expensive as a similar Sigma lens. A Tokina 2.8 AT-X 80-200mm is only appr. 50% of the Sigma. This makes the Pentax lens is 6 times as expensive as the Tokina! Is it really worth this it?
