Hi - ths sounds like a stupid question but I am somehow stuck in technology A few months ago I bought a Metz AF-1 58 for my K20D - The flash worked fine in p-ttl mode and I made good pics. Now I wanted to use it again and somehow the flash is not showing ttl as possible mode and it seems not to communicate with the camera anymore (does not react on zoom changes, does not react on aperture or iso changes and makes no aligned pics. Who knows, how i can re-active the p-ttl mode?
