I am looking out for a Olympus OM-4 or OM-4ti camera to complement my OM-2sp camera. I already know that early versions of the OM-4 have battery draining issues. On several internet boards I also read that Olympus changed the circuit board of the OM-4 to fix this issue. The new OM-4 circuit board is supposed to be the same as the one used in the OM-4ti. The only information that is missing is the serial number range of OM-4 models with the fixed circuit board. Does anybody have some insight in this issue?
Thank you very much for reading.
All the best,
