To connect new flashes as the HVL-F43M or the HVL-F60M with older Sony cameras (eg A37, A57, A65 or A77), you have to put in between therefore this adapter (ADP-AMA). Newer camera models like the A58, A99 or 3000K need the adapter is not because they have already installed the new ISO flash shoe (the need reversed the Adpater ADP-MAA, when older Sony flashes as the HVL-F43AM or HVL will connect -F59AM them).
The adapter has an overall stable impression.
It loops through all flash functions, so you can use the new lightning without limitation with older Sony cameras.
It is annoying that Sony still for the program located cameras like the A65 and the A77 does not provide without adapter matching flash more, but for the adapter can not. It contributes on the contrary to mitigate this problem.
