Hi Jim,
there is hardly anyone who has ever criticised the 105mm MACRO. Thus, I really believe, it is a very fine lens.
Although I am very much in macro-photography, I do not own expensive macro-tools.
First I started entering the macro world making use of the old M42-screw-mount tools.
This way, the macro world is open to those, who cannot afford highly expensive macro-equipment, too.
Example: LOW BUDGED Macro Tools ...

SD9 / M42-mount adapter / macro-rings / PORST M42 75-260mm Telephoto MACRO (made in the 1970s).
Testphoto (employing the above equipment!)

SOLIGOR AR-30-T (ca. the late 1970s) MACRO-RING-FLASH
This LOW-BUDGED macro solution can do an extremely good job.
It perfectly goes with SIGMA's LOW-Budged 28-80mm MACRO lens ....
