Or is it just the fact you can use auto aperture on the body???? with the extra cost.
The prices I've seen for the Super Tak's usually are more than the smc M 200 f4. I suspect that the only difference in the M and the A would be the auto aperture but I couldn't say between the Super Tak and A.
The K has 5 elements in 5 groups and weighs 537 g and is 137mm long, the M has 6 elements in 5, the 6 in 6 and the A and M both weigh 405 grams and come in at 111mm in length. Go here to check out the 5 200mm lenses

Now, the SMC A* 200 f2.8 ed or SMC A* 200 f4 with macro are another story regarding price and would like to get my hands on the macro one!
Edit: I guess I overlooked the K 200 f2.5. The 3 FA* and DA* lenses are on that list also.
