Now that I have the SCA-356 working I can use it with my SL3003. This is pretty nice, I got my first SL2000F when in school and a Metz flash and adapter was un-imaginable due to the excessive cost. So, for the first time in 30 years I can experience TTL flash with my Rollei. I see that the Metz has an EV setting , so, by balancing the existing light, with the cameras exposure meter, I can manually simulate TTL-fill flash like the Hy6 and 6008i can do. Obviously it is a little limiting due to the slower shutter speed available.
