All Voigtlander lenses are likely to be sharper than the collapsible.

This statement is definetely untrue.

Collapsible Summicron 50mm f/2 @ f/2.

The later type 1 Rigid Summicrons have improve/harder coatings. The construction also changed lightly. I believe that the earliest Type 1 Rigid Summicrons were slightly different optically from those that follwed, based on taking a 14x apart.

And I agree that there is some "magic" to the Collapsible Summicrons. If you blow up 100% crops, they are slightly softer than the Rigids. I just like the 13x collapsibles better. They are not hard to work on, the Rigids are a real pain.

Brian,
In your opinion, when did the rigid summicron become sharper? Is there a cut-off serial number you could guess?
 
I've never been disappointed by my collapsible summicron. There hasn't been an image I've taken with it that I've wished was with another lens.
 
Raid- there were several versions of the Rigid Summicron over the decades. i suspect the statement was in regard to Type 1 vs Type 2, Type 3, etc. "Sharper" is a more subjective term, and is not the same as resolving power.

Now: within the Type 1 Rigid Summicron/ DR Summicron, the Optics Module seemes to have been tweeked early on at ~15x. The later lenses, post ~1960 or so, have better coatings. Probably around the time the Summilux was introduced. Again- I'm not citing official records, just going on taking a few apart.

I've noticed that the 14x rigid Summicrons have a purple coating on the front glass, often damaged. The 15x rigid Summicrons have a blue coating, often still in a very good condition.

That is my experience as well. I just repaired a Summicron Ridgid that had THREE elements put in backwards! That tended to reduce its sharpness.
