You can tell that many companies were in a rush to announce their products for Photokina because many of them are not yet ready to ship them. After Sigma and Sony, Olympus is next to issue an apology because their latest M.Zuiko Digital ED 40-150mm f/2.8 PRO lens and 1.4x MC-14 teleconverter will be delayed "due to hight demand". It's just hard to believe that many m43 users dropped $1,500 on that lens. The new shipping date is November 29, 2014.
