I have K mount cameras but no M42 at this time, thought about getting some M42 mount stuff because my first camera was a Ricoh Singlex TLS (long gone from my possession.) What's the significance of removing a spring?

The spring keeps the mount on securely. But, then, it takes a tiny point to push it in to remove the lens. With no spring, the mount moves on and off freely. That can be dangerous if you forget and turn it till the lens and mount pop off. I prefer the spring but some do not. Thus, Collin is neither right nor wrong. - David Lyga

When you say it takes a tiny point to remove the lens, do you mean from the mount, or from the camera? If it holds the adapter to the lens but the combination is still removable in the usual way from the body, that would be best if you had an adapter for each lens, without the spring if you were making one adapter work for multiple lenses.

Come to think of it, I'm not sure which way this adapter goes. Does it allow the use of M42 mount lenses on K mount bodies, or K mount lenses on M42 bodies?

CollinB, are these genuine Pentax adapters? If so, I'll take one.

Roger, they allow the use of M42 lenses on a K mount Pentax. They work well and there are some fantastic SMC M42 lenses out there...and they're typically a bargain and produce beautiful photos. RJ
