Tonight I picked up a Minolta 5600 HS-D flash for € 135 to go with my NEX-6. The ADP-MAA adapter is required to mount the flash. Sorry, horrible phone pic, the NEX-6 is my only serious camera after selling off my µ4/3 gear. The only thing that's left now is an Olympus FL-50R flash which I'm going to sell shortly. You definitely need to try out before you buy, I went after another 5600 HS-D and though it seemed functional it didn't work on the NEX-6. Played around a bit for the last hour. TTL actually seems to work in conjunction with the NEX-6, exposure looks accurate and the lighting looks very nice too when bouncing. A much better experience than TTL with the Panasonic GH2 and the Olympus flash, where exposure was erratic. Other users on mu-43 had the same experience.
