gee-bug Posted September 26, 2005 Share Posted September 26, 2005 Anybody have experience using Pentax 645 AF lenses on the *ist DS with 645 -> K-mount adapter? Do you lose the AF functionality? Is stop-down metering required? Any info would be much appreciated, thanks! Link to comment Share on other sites More sharing options...
mawz Posted September 26, 2005 Share Posted September 26, 2005 You lose AF, Stop-down metering is required. The Adaptor is merely a ring of metal and does not provide any meter or AF coupling. Link to comment Share on other sites More sharing options...
