Olympus has released a firmware update for the E-P1 Micro Four Thirds camera, along with updates for the M.Zuiko Digital ED 14-42mm f/3.5-5.6 and 17mm f/2.8 lenses.
The firmware update for the E-P1 is described as providing improved operation when using the C-AF, which is something that I found to function quite poorly in the Olympus E-P1 Review. The firmware updates for the lenses are described as providing improved AF operation.
You can download the updates on the Olympus Japan website.
so, does it indeed improve AF?
