I have an adapter Minolta FS-1100, cameras Sony A77 and A100. I want to know can I use it with flashes Sony F43M, Sony F60M and studio radio triggers?
The F43M and F60M require the Sony ADP-AMA to fit onto your iISO Minolta hotshoe on the A100 and A77 (not required for the A77II). The Sony ADP-AMA is the ONLY adapter that allows the F43M and F60M to be fully compatible with the iISO hotshoes on the older Sony dSLR/SLT cameras like the A100 and A77 so don't bother looking for an alternative.
The Minolta FS-1100 is just a dumb adapter allowing the use of ISO triggers on your A100/A77 Minolta iISO hotshoe, get the ADP-AMA if you intend to buy a Sony MIS flash.
