Tricks for focus-aid and old lens
---------------------------------
I have a PENTAX-Z(1) and an old lens SMC Takumar (400/5.6 screw mount),
but I use it as K-mount lens: the adapter is glued and bolt is removed.
As say the manual focus-aid doesn't function.
With an old Cosina lens (5)0/(2).0 similar to M lens (but with black
paint mount), focus�aid doesn't function; however him function with
metallic extension tubes!
I looked for the reason and I placed a sheet of paper plated between the
mount of the body and the lens; I also tried to use a Auto Extension
Tube (métallic mount).
Miracle, the focus-aid functions !!
I cleaned the painting on the lens near the mount, and the focus-aid
functions now without problem (selector both on single or manual
position).
