Maybe someone can help me with a little information on the Metz 386 adaptor. I bought it used so do not have an instruction manual. I have searched online but can't find anything. If I want TTL flash metering on my SQAi do I simply.. 1, Set my gun ( Metz 45CL4 ) to TTL . 2, Set the film speed on the gun 3, Set my aperture and shutter manually on the SQAi 4, let the camera and gun do the rest. I use a WLF or a non metered prism......or do I have to have a metered prism?? Thanks.
