Hi there Don't know if this is a common problem or a well-known solution but here goes: My A70~210 f4 was getting loose on the zoom / focus ring. Although the mechanism itself was nice and tight, the ring wobbled. After a little investigation I found that the ring is held to the lens mechanism by a metal ring about 3mm wide, fastened with four small (hobby-screwdriver size) Philips screws. This ring resides beneath the grip rubber at the camera end of the zoom / focus ring. There is no need to remove the rubber grip, simply peel back a few mm at this end. Tighten the screws (maybe add a smidgen of thread locker) and the lens is as good as new. Apologies if this is common knowledge but it saved me a trip to the repairer so it may help someone out there!
