As originally built the APO extenders won't work on the SL or SL2 but  
where there's a will there's a way.  These extenders can be modified  
to fit the SL and SL2 retaining the auto-diaphragm and on R bodies  
also retaining the full-aperture metering.  On the SL and SL2 you'll  
have to use stop-down metering.  Better off starting with the non-ROM  
extender 'cuz the ROM has to be removed in most cases for this to work.
