The price of secondhand 4/3 lenses seem to still be dropping. Granted, I already have one 4/3 lens - the ZD 12-60 - but I'm finding myself wondering whether I should take advantage to add a few lenses I've been eying for a long time - namely the ZD 50-200/2.8-3.5 (<$400), ZD 35-100/2.0 (<$1200) and ZD 50/2 macro (<$250). But even the 14-54/2.8-3.5 (<$175), 11-22/2.8-3.5 (<$300) and 14-35/2 (<$1200) are starting to look attractive. The problem of course is autofocus. For the good lenses (the 14-54II excepted) AF barely works on m4/3 cameras. It's loud, slow and inaccurate. In theory, Olympus will be releasing a camera in 2013 capable of taking full advantage of these lenses. However, I do have misgivings: Will the camera also accept m4/3 lenses? The rumors have been typically unclear on that point. Will Olympus's definition of usable autofocus meet mine? They've done well recently (native lenses on the E-PM1) but not nearly so well in the past (see the E-3). Will the camera be a brick aimed at the E-5-toting members of the 4/3 faithful, or something more in line with the E-M5? Will the camera be a one-off item - a special design just to placate 4/3 lens owners until native replacements exist? The question for me is - is it worth picking up some of these 4/3 lenses based on the assumption that there will be a usable body for them by the end of the year? The upside is obvious - good lenses, at very good prices. Of course if the camera isn't what we're hoping for, the downside is that the lenses will be useless to me thanks to the poor AF. Thoughts or suggestions?
