I see, is the 200 2.8 the one that it doesnt have it. I wonder why didnt implement it if both were made at a similar time (actually I think that the 200 f2.8 was made after the 180).
I have the 200 2,8 and it is amazing (and amazingly heavy ~3lbs) but it looks like you already have another outstanding lens in that range. Having the problems that you describe I would follow Budha's advice (I mean Budha Jones's advice althought the other Budha was also famous for his advices

)
