BOOWU + DMUOO + Summicron?

Hi,

 

I'm wondering what it takes to use the lens head of a 50mm Summicron on a BOOWU.

 

The lens is a Canadian 11819, serial 335xxxx (c. 1985?), and the BOOWU is the screw-mount version.

 

As far as I can make out the DMUOO/17672 adapts the Summicron lens head to LTM mount (e.g. for enlarger or bellows).

 

But does anyone know if it (a) fits the 11819 lens head as well as the original rigid/DR version and ( has the correct focus register for the BOOWU (i.e. infinity if fitted directly to a body).

If I understand well you have a BOOWU for LTM and a Summicron M rigid so you will need

a LTM to M adapter + 17671T adapter + 16508 adapter + Summicron head.

I tried it with the M8 it works, remember to close the dia. as much is possible.

Thank you. That makes sense ... but looking at the 1975 general catalogue (the Hove reprint) I wonder if 17671T + 16508 = 17672.

Rereading the catalog I seen that the same ring 17672 is used also for the bellow II with the 16590 large ring and remembering that I have this set , I just tried it now and it woks verywell with the combo.

Hoping this help.

Perfect! Thank you very much for the experimentation. I shall buy a 17672 with confidence.
