I got an om-10 of a garage sale and later I got the manual adapter. Three questions: 1. the flash that came with the camera - T20 - fits nicey on top of the camera in the hot shoe but in front of the camera there is a socket for a conection of some kind of 3 cord wire- what is that for and do i need it? 2. The manual adapter- is it right that in manual adapter position it overules the automatic time setting of the camera though it is stille the automatic value displayed in the viewfinder? 3. The lens, an olympus zuiko 1:1,8 50 mm is that a: a. crappy lens, an ok lens, a good lens or a superp lens? I am used to work with canon and leica on with the 24x36 format but mostley wide or tele and I have not got a 50 mm to compare it with.
