Hello! I am confused.. I just tried to play with my new *ist DS and mny old AF500FTZ flash. I have tried ISO of 200 and 400 with lenses Pentax F 50/1.7 and Tokina ATX PRO 28-70/2.6-2.8. The aperture setting on the lense was set to "A". I found that TTL just does not work, and the flash seems to fire to the full power.
I thought the TTL should work in this combination with DS, (the manual says that it should) and I know it worked with the *ist D (the same lenses and flash). Any thoughts of I might be doing wrong? Thanks, Igor
