I have one I really like. I never heard of sticky mirror but will gave to look it up now. I got lugs (and the camera) from KEH with no problem except for the $20 or so price tag.
I wish it had exposure memory lock but that's the only lack I see. Great camera.
Mine had sticky mirror and just about everything else, including the serious focus problems. I sent it to Eric at pentaxs.com and had it completely overhauled. Now it's like new and simply amazing!
And what is a "lug"? Most cameras have a thing with a hole in it into which a ring is inserted, and it is called a lug. On the LX (and the medium format Pentaxes) a post projects from the body and is usually called a lug, while the swivel part that attaches to it, and to which the strap is attached, is also usually called a lug. Oy.
I think the Hasselblad type strap will fit the Pentax 645 and 6x7 format bodies but not the LX.
Yeah, it's fairly confusing...
A Hasselblad strap to an LX? I don't think so.
One of my LX bodies didn't come with the original Pentax clip on strap clips, so I purchased the OP/Tech Super Pro A strap which attaches to the bare metal lugs on the LX body. This strap also fits Hasselblad 500 and 503 series bodies (if not other Hasselblad bodies).
