Does anyone have any info on this lens? I can hardly find a mention anywhere. I'd specifically like to know the flange focal distance at infinity. Thanks

It is a lens made for a darkroom enlarger and a very good one for that purpose.
You will need a bellows or a focusing helicoid to use this on a digital camera.

Thanks Tom. I've had success using enlarger lenses for landscapes with the Rodenstock Rodagon Apo N 50, 80 and 105mm lenses. I'm using a Cambo Actus and I would be pushing the limits with this focal length to focus at infinity. |

I don't know this one, but tracking down what the designation 'HM' means might point you in the direction of their particular selling point.
John Jovic records an Apo-Componon HM 4.0/45 with a flange focal distance at infinity of 42.4mm. But no 4.5/44.

HM is "high modulation" which I have been meaning to ask Klaus about. The Apo componon HM are schneider 's very best enlarger lenses. You can still buy them new, if you have the money.

Aye, I've looked in all the usual places but the specs for this lens cannot be found.

The Apo Componon 4.5/44mm has been used in scanners. Obviously something for industrial applications.

I came across this on Flikr…
"APO-Componon HM
These are 6-element, 4-group apochromatic enlarger lenses, using high-modulation glass elements,
designed for critical color rendition and precision industrial applications."
Funnily enough, no mention of your 4.5/44. |

Would love to see your pix of and with this lens - the 44/4.5 was a new one for me, too. Do you still have it? Perhaps you measured the FFD?

'Apo' seems to have been added pretty randomly: HM is the more reliable badge of quality. Not too far from this focal length there's even a Componon-S HM 50/2.8.

Incidentally - if you don't still have the lens, can I get your permission to reproduce this image in the DeltaLenses.com catalogue?
Thanks.
