the AMAZING Nokton 1.5

I now have the Heliar 50/2 a nd 50/3.5, and both lenses are very special. I have tried out the Nokton but I don't own such a lens.
Yes, it's surely the least intrusive collapsible, since it doesn't protrude behind the mounting flange at all. I even had mine 6-bit coded and use it frequently on my M8.does anybody know if the heliar is colapsable on a M8?
Other disadvantage for me is the 39 filter size that is uncommon now making difficult to find easily any new filters of this size.
