Report "I own toe Metz 58 Af 1 Flash units and both just after one year broke down. In both cases the main Flash tube exploded inside the unit and had to be replaced with what was available here. But yet each time they fire they release a sound which was not there when it was new. And aslo both intermittently give more power and does BURN pictures when on TTL mode. One flash Gun permanently does not support the infra red function for focassing. I am disgusted with these and have lost faith in Metz Flash. Please help. I am Visiting Kuala Lampur Next 18th for 5 days and hope I can get these attended. Prasanna Somapala"
