I have been following this thread with increasing enthusiasm for the idea of getting myself the TAP. How disappointing that it now appears to be badly flawed. Luckily I had not actually ordered one. Waiting now for a redesigend TAP to prove itself.
No doubt a rational decision but I honestly believe that, in foregoing the purchase of the "flawed" TAP, you're possibly denying yourself an inordinate amount of sheer photographic pleasure. I say "possibly" because I have no idea what lenses you intended to use with the TAP. I'd become progressively more disenchanted with the direction Sony has taken in designing huge fast prime lenses (35/1.4, 501.4, 85/1.4). The Loxia line is the optimum size for native FE lenses IMO (I did succumb and buy an FE 85/1.8 but it is relatively light). The TAP has (almost miraculously) provided AF for a huge range of small M and LTM mount lenses and made it possible to work in a relaxed, fluid, and unobtrusive way: camera held at waist level with fast, accurate AF. In other words, heaven on a stick.
I've just checked both of my TAPs ("Buy a pair, keep a spare" as a friend of mine used to say). Neither exhibits the wobble. I've always felt that the 700g limit for lenses attached to the TAP is wildly optimistic and, apart from a single usage of a Distagon C/Y 35/1.4 (which I found unpleasantly cumbersome), I've restricted my TAP usage to smaller (mainly 50mm M/LTM mount) lenses. The heaviest lens I regularly use is an M-Hexanon 50/1.2 which, similar to Fred's Distagon 35/1.4 ZM, weighs about 390g. So It's troubling that Fred encountered problems with his Distagon. I guess I'll just have to keep an eye on it.
