You're welcome.
The 80-200mm mentioned by Apet-Sure isn't so common, I've tried to pick up one cheap a couple of times and been outbid, and TBH tho I haven't tried it I suspect it's just another good one that's got a bit overrated here on PF.
I've been doing a considered comparison of the 3 rated vivitar series 1 70-210's with the 2 tamron adaptall SP 70-210's and kiron zoomlock 70-210mm. And the best at 210m was the underrated and underpriced
52A! You can see my web page
