Further to the last big discover for how to revive a dead SDM even the last method didn't work, I've seen this report lately which verifies that the new (escalated) method does work to bring back live again for a dead (stuck?) SDM! :-o

Nice! Should Pentax should include these two methods into their service manuals of all the SDM lenses such that they need not to provide expensive quotations to the SDM users anymore for total SDM replacements and at least Pentax should try these low-cost repair methods at the first place instead! ;-D
