I have a Sony NEX-6 camera and HVL-F32M flash. I'm considering acquiring a Minolta 3600HS(D) flash for about $85 shipped (from a reputable source with a 30-day return policy). I plan to use the Sony flash on the camera and the Minolta flash as a TTL wireless remote. I'm a frugal amateur, but I hope with these flashes and an umbrella reflector I'll have better lighting options for portraits, still life, and macro. Does this seem like a reasonable plan? Am I correct that these two flashes and the camera are compatible if used this way?
