My Pentax digital spotmeter lost all of the tiny little screws that hold the small retaining/aperture window guide ring encircling the outside 1/4 inch or so of the lens.
I guess vibrations from carrying it around in car did them in.
Question is this: does anyone happen to know the size and thread pitch of these little buggers?
Seems crazy to send it in for a repair when all I need are the screws themselves and a brief hiatus from coffee consumption.
Start with a good hobby shop -- they should carry down to 1-72 or 0-80. If those are too big, or if you need metric screws, McMaster-Carr has down to 000-120 or M1.

Ask Richard Ritter. He repairs / calibrates them. Excellent work and quick turnaround. He might well be willing to sell you the screws too.Originally Posted by clay harmon

Richard Ritter .... www.lg4mat.net ..... probably has boxes full of hem.
You might try the fasteners aisle in your local hardware store. I lost a couple of very small metric screws from my Linhof viewfinder. I despaired in being able to find replacements, but measured them with a caliper, estimated the pitch, and found identical screws at my local dealer.

Once, you find some replacement screws, I would recommend using some Loctite or other brand of thread locking material. Then they won't fall out again.
