[OM] 2X-A Teleconverter Lens

I've been using the 2X-A Tele converter lens along with the
38 macro and auto bellows.  I install the tele converter to the
camera and then the bellows & then the lens.  I get some outrageously
sharp magnification. Lighting is done thru the T-10 Ring Flash.
I find it is most important to make sure everything is tight on the
macro stand and that the bellows is locked just right.  I replaced
the original locking blocks with some newer ones.  Mirror lock-up 
does not seem neccessary because the only signicant light is from the
flash.  I'm more concerned with slight bellows movement on critical 
focus.  I ofcouse use the Varimagnifier.  I mostly shoot micro
processors either in package or off the wafer.  I've also shot diamonds
for identification.  I'm guessing my magnification is well over 10x
or more.  I shoot at about f8 or f11 and sometimess 22.  I can't really
tell if this makes much difference. 

Has anyone else used the 2X-A in conjunction with the 38 macro or 20
macro?
