Apo Componon Hm 60,80, 90 are 100% the same lenses as Apo Digitar 60,80,90
Apo Componon HM 150= Apo digitar 150
Apo Digitar 210 mm would be indeed Apo Componon Hm, but there was only non HM 210 componon made for film, so the Apo Hm exist only as Apo Digitar.
Apo Digitar 120 is Apo Symmar 120 mm (72° version, not L version)
Super Angulon 47 mm= Apo Digitar 47 mm
To understand the name digitar it is important to know that this is NOT a name of a special lens design!
Componon, Angulon, Symmar, Xenar are lensdesigns, Digitar means only that this lens is good for digital work, but the lens design is componon, Angulon or Symmar. The same with rodenstock Apo Sironar Digital lenses that are Apo Grandagons, Apo Sironar S and N.
There are indeed some lenses that exist only as digitar- or apo sironar digital like 35 xl, 43 xl or Roddy 90 , but they are also S.angulons/grandagon designs.
At the start of the digital photography the lenses in the digital schneider shutters had the desigh name componon, symmar or angulon and the second digitar or cambonar name.
Later schneider started to use digitar name only, than added the Apo name, after Roddy started to use the Apo sironar digital name ( Why? becouse too much peaople ask if their lenses are worst that roddy becouse thay have no Apo name- silly but it is buissness).
I hope this helps...
