yes, you still do it ( m42) by feel, the same way you do it in good light, there really is no point in ever really looking at it, but its much easier to "feel" that the lens barrel is approximately perpendicular to the flange and start the threading by rotating it, than it is to do a K mount by feel because with the k mount you have to feel around for two bumps/levers/ buttons (one on the body and one on the lens ) and align those up to install the lens and on some of the newer lenses and bodies this system is no longer even available on K mounting. I do not know what you mean by multistart threading but its not hard to start solely by feel at all. jco

You still have to align the start of the lenses thread with the start of the bodies mount thread. Which is done by feel. Just like mounting a K mount lens. I admit I haven't looked that hard at my Spotmatic & small collection of M42 lenses that my boss gave me, but is it a multi start thread?
