Thanks a lot mate. I just did the modifications as you suggested step by step. Worked like a charm for me ;-) ---------- Post added 10-01-16 at 01:14 PM ----------
Thanks mate. Mine worked too but I kept the original baffle (cardboard and black flocking material for telescopes).
I did a few tests and I noticed something strange with my K-1. When I zooming in the longest range and I shut the aperture to say f/9 in Av mode, I get an overexposed picture of about 2 stops. Not sure if it is the modification but it is something I never noticed before.
*** Edited message ***
Found the culprit. It was my "Cardboard baffle" that was a tad too wide and was exercising some pressure on the aperture mechanism and preventing the lens from shutting the aperture. I have fixed it now and it works.
Lesson learned: if you choose to go for the homemade baffle vs dremmeled one, make sure you measure it to the millimeter and test that the mechanism is still working inside the lens.
