... so I'm now thinking of getting an adapted FT zoom instead. More specifically the 14-54II. My thinking is as follows: the only fast midrange zoom for :43: is the Panasonic 12-35. I have no reason to doubt it's a marvelous lens (haven't used it myself) but there are several drawbacks: 1) Cost; best price in Europe is more than 900 euros 2) I'm totally indiferent on OIS since I'll be using it on Olympus bodies; this is a feature I'd paying for and never using 3) Most serious of all: the focal range doesn't suit me very well. I'd like more of a "walkaround" type of lens, certainly going to 50mm at the long end although I don't mind that much on the short end (14mm is fine). I guess Olympus shall have such a native lens at some point, but this could be by the end of the year and would cost perhaps more than the Panasonic. So I was thinking. I can get a great used example of the 14-54II for 350-400 euro, including the adaptor. For the shooting I'm planning with it, breakneck AF speed is not critical. OTOH, the 14-54II is perhaps the fastest focusing FT lens available, and, if we believe Olympus' claims, FT lens AF is improved in the E-P5 already; and would improve even more in a future body. For me getting this lens would allow me to replace both Sigmas (19mm/30mm) and probably make some money against its cost in the process. I know I'll sacrifice some AF speed but, from what I've seen, no IQ loss. My concerns are twofold: 1) I have forgotten back/front focus issues since I abandoned DSLRs for mirrorless. Is there a chance there are focusing accuracy problems with this lens? 2) On a recent thread (https://www.mu-43.com/f40/olympus-zd-12-60-af-motor-failing-again-46438/), Dara talked about reliability problems with the 12-60 when used with CD-AF cameras. Would this be a serious problem with the 14-54II too? What do you guys think?
