I just bought a SMC-M 50 1.7 that takes great pics. It is in very good condition and I realize that a few internal dust specs probably aren't worth worrying about. I just don't like seeing them in there. Can anyone reccomend someone qualified to disassemble the lens and clean it? I only live a few miles from the Pentax national service center in Denver, but they say they won't work on lenses this old anymore.

Leave them alone.

If you get someone to clean the lens, you'd probably end up with more dust specs in the future.

No one likes seeing them in our lenses. It's just justifying the expense of cleaning them out.

You might end up with a paper weight.I know that I did.

alright already. I got dust specs. btw, the camera (zx-m like new in original box) lens (except for the dust spec looked like new) and a brand new fg battery pack all off ebay for $45 for the works! Just got back a roll of E100G from the Slideprinter in Denver and the pics of my standard test subject--Denver Union Station, are the sharpest I have ever shot.

Wolfee, even the best repairers can clean a lens and render it unusable - as I found out to my horror 20 years ago. Mind you the same (manufacturers official) repairer also proved totally incompetent at camera repair 3 years ago. (Not Pentax BTW)

If it's working well as you say just live with the dust specks :D

If they are dust and not fungus, no problem. Always look only through the viewfinder and never into the front of the lens, and your photos should be fine.

I had a bit of dust in my lens.
Tried to clean it myself.
Things got out of hand.
