So, do you have an idea if it would be possible to mount a 150mm Componon enlarger lens in a Copal shutter? Also, do you think they are multicoated? They are quite cheap on ebay...
best,

Only the latest Apo Componons HM are multicouted, these is exactly the Apo Digitars.
The classic Componons/ Componons-S are all single couted.
The Apos deliver best performance already wide open, the componons 2 stopps down.
The performance is in praxis very close till not visible.
I cant see any diffeneces at pictures that i took with the apo digitar 80 and the componon s 80 mm.
The MC is less important as many think.
All componons can be used with copal shutters afcourse
Componons are 6 elements symmars with little improvents for their specifical use.
Their image circle is as I remember little bit less ( 68° I think, at 22/infininty) but they are very similar to the symmar-s.
I tested for me also late symmar-S MC from 80.. lenses and compered them to Apo symmars, Apo Sironar S and Apo Dgitars and Apo Sironar Digitals ( same lens as Apo Sironar S) and was very surpraised. All tested lenses were 180 mm, only the apo digitar was 210 mm. So the best was the Apo digitar 210, than comes the symmar S! hart to believe but true. The symmar S have only one disadvantage, it was very hart to focus. After i find out how to avoid this focus shift I could not believe that this lens cleary outperform the Apo sironar digital. I also tested older symmar and symmar s and they was bad. The G-claron 210 mm was also a great lens.
