As expected Olympus did not announce any new product at Photokina
Olympus is the only major company not having announced any new product at this years Photokina. Granted you could actually count in Sony too if they would not consider the 24mm GM lens they announced the last week. And Ricoh-Pentax at least announced the GRIII development.
But big news is coming in January with a new OMD camera to be announced!
