I also have DSRL-Exchange-adapters(no sharp at infinity for mirror-clearance in certain FFs) where we will try to add Optixpcb-chip v6(newest) later. For those not knowing: the latter is the only adapter(to my knowledge) with screws for permanent and solid attaching to lens .<br /><br /></p>

Any switch that a lens would actuate

when mounted is probably not going to

have trouble with being left on.

Remember that people generally leave a

lens attached to the camera. Because

of that, the switch would be designed

to spend all its time in the "on"

position and this would not be

different.

<p>maybe the only problem is the spring being under tension all the time. the same for the m42-lens-pin being pushed all the time. will now get optixpcb-m42-adapter too with pin untouched.<br />btw: for DIY-tilt-construction of 80mm biometar(pentacon6-lens) with m42-mount plus adapters. lens pin must be untouched, by drilling a hole into rubber. its on youtube, wonderfully working. 10 min. job.</p>
