"Note the word "compare" is embedded in "Comparon"
refering to its 1:1 abilities. Not to be confused with
"Componar", Schneider's economy line of EL lenses.
Their top line was "Componon". Note the "non". You
can remember "non" is their best, as "No one" made
anything better :-) "

Componon is Schneider's lens for close field work. The Componon could be gotten with mounting threads on the rear cell or the body of the shutter. The Componon is for darkroom or studio work. The Componon and the Componon-S refers to field coverage, as the Componon has 80 degrees of useful coverage while the Componon-S has 100 degrees of coverage.

The Comparon is for 'general and landscape work having 80 degrees of coverage.

The Componar is there basic enlarging and 'close field' lens.

ALL Schneider lens are designed to have optimal performance at f22.

The only decent optics from Schneider were the Componon-S and the Schneider Super Angulon (100 degrees coverage) the f8, 121 Super Angulon was legendary. The Schneider Super Angulon had an hour glass shape. When purchasing the Componon-S, buy as an enlarging lens and purchase separately the shutter so it can be used forward or reversed.

The OP was needing to use existing enlarging lenses they already own. I doubt that they are going to run out and buy one of your lenses with a shutter in it seeing as that came at no extra charge with their camera.

How do you know that? The OP hasn’t said, and hasn’t bothered to respond to anything. Probably went elsewhere looking for knowledgeable advice.

Read the original post.
ENLARGER lenses.

Timmers Loc: San Antonio Texas.

Years ago a friend got into macro photography. We tried old motion picture camera lenses, 8mm and a few 16mm camera lenses. Of course we reversed the lenses when we tested the lenses. Surprisingly, these old film camera lenses are quite suited to macro photography.

Everyone else knows the OP hasn’t said whether he has either a lens or bellows!

Architect1776 Loc: In my mind

Read again ENLARGER lenses.

The OP said
"Does anyone know how to use enlarger lenses for macro photography on a bellows"

So whether or not the OP has an enlarger lens or a bellow it's irrelevant as he wanted to use an enlarger lens on a bellow he would have to get them.

Architect1776 Loc: In my mind

That is right.
Not camera lenses for view cameras needing shutters.

RWR Loc: La Mesa, CA

Good grief! didn’t you or Architect1776 read the quote I responded to?
‘‘The OP was needing to use existing enlarging lenses they already own.’’
Or can you not understand what you read?

Architect1776 Loc: In my mind

Read my responses.
You have difficulty with them.
The assumption has always been that the OP has an enlarging lens in ALL my responses.
I have been the only one to actually show a real world solution not just theory on how to set up an enlarger lens on a bellows and attach it to the camera.

RWR Loc: La Mesa, CA

Thank you for affirming my point.

BebuLamar

Now I have a question about using enlarger lenses on cameras. Should I reverse the lens. Reversing the lenses isn't easy as each of my lenses may have a different filter thread diameter. So I wouldn't want to go thru the trouble unless I gain some sharpness.

If they are a symmetrical design, it won't make a whole lot of difference. If they are Asymmetrical then yes reverse them....

FWIW, you can and in some cases should reverse macro lenses too !....
