Jeff -
No, no need to recalibrate for different lenses.  Dont know personally how well 
the Sinar meter works - they were always terribly even ridiculously expensive - 
I have always used a handheld light meter and then corrected for bellows 
extension if necessary, and for reciprocity law failure for long exposure if 
necessary.

Bob, it does indeed have the fresnel lens installed.  Sounds like the Minolta 
probe would have to be recalibrated for each lens?  Does that make sense?  


 


Do these Sinar metering wands work well?  It seems like TTL metering would make 
life easier especially for macros and such....

The meters where a probe is held against the ground glass are tougher to 
calibrate for consistent good exposures because they read through the 
additional density of the ground glass.  The Sinar meter's wand is right at the 
film plane in front of the ground glass.  Just a matter of calibrating the 
meter to take the density of the ground glass into consideration.  Would not 
work with a fresnel lens over the ground glass - I believe there was a fresnel 
lens on the camera in the picture if that was the same camera.
