Can the collapsible Summicron head be unscrewed?

I read elsewhere in this forum that the 50mm f2.0 Summicron's head could be unscrewed to use with the Visoflex. I have the VSPOO adapter and am curious to try some macro with my collapsible 'Cron and my Visoflex and bellows, but am afraid to force the lens head without verifying that the head can be unscrewed. In the thread I found this information they were discussing a rigid Summicron. Answers?

To the best of my knowledge, it is only the rigid Summicron that can be used in this way, NOT the collapsible.

The head from the Rigid Summicron can be removed, and there is an adapter for the head to screw into a 39mm mount for the bellows. I'm not too sure about an M-Mount collapsible Summicron, I;ve disassembled one before. It is not a removable head in the sense that the Rigid lens is removable. I've done some close-up work with my LTM collapsible Summicron. It works quite well.

Mine's a screwmount collapsible. I guess I'll hang on to the adapter until I find a rigid... I have the 135mm Hektor and it's adapter to play with! Thanks!

Hi.

- The VSPOO adapter is of no use on a Visoflex. It is thought for sliding focusing stages.

 

If you want to use your bayonet mount Summicron 50 (collapsible or rigid) on a bellows, look for adapter 16469,

or you can use it directly on the camera as a macro device as well with a device called

SOMKY-M (+ adapter UOORF for lens head):

On a screw mount Leica, use the NOOKY close focus device:

Thanks! Valuable information.

For macro work: If it's the screw mount collapsible, it should mount right onto the bellows. Just use it in collapsed position, or extended. No need to unscrew the head. I've used mine on a Nikon DSLR using a 39mm screw mount to F-Mount adapter.
