Body group OM-4Ti
The OM-4Ti is an improved version of the original OM-4. The titanium top and bottom
plate make the camera stronger and the electronics has been improved to reduce the battery
drain that was clearly too high in the OM-4. Support for the F280 flash, that was
introduded at the same time as the OM-707 adds flash synchronisation at all available
shutter speeds for easier daylight fill-flash.
Currently the OM-4Ti is only available in black. Originally it was made in 'champagne' (which was not a chrome finish or bare titanium, but painted titanium).
