Hi,

I recently purchased a PTL 12.5-100 zoom for my EL that came without instructions - I have by myself and with the help of friends figured out the functionality of all the knobs and bits but with one exception ...

Take a look at the attached pic, its below the aspheron switch and looks like a button but is instead a threaded ring which can be undone but only up to a point ... it feels like it should come off as it gets loose but there is something physical stopping it from coming off (I thought it looked like another battery compartment, but no ...)

It could be either malfunctioning or I am not observant enough but undoing it or tightening it up has no noticeable effect on the functionality of the lens (the auto-iris, power zoom, DOF preview ...) :ph34r:

Any ideas ?

cheers in advance,
nick
