Shadrash, I don't know the answer to your question. However, I think that it would be "yes." Consider the following:
1. On his website, Stephen Gandy indicates that the modern 50 Elmar is fully collapsible on the Bessa R2.
2. The body of the Hexar RF is deeper than the body of the R2 (35 mm vs 33.5 mm).
3. Because the motor-driven shutter of the Hexar RF resets itself instantly, it does not need or have a second set of light protection shutter curtains that the Bessa shutter does. This means that there is even additional room in the Hexar RF body because the shutter isn't as thick as the Bessa shutter.
4. In his discussion of the Hexar RF on his website, Dante Stella addresses the issue of collapsible shutters - although not this one. Both the collapsible 50 Summicron & the 50/3.5 Industar collapse fully. He just warns not to jam them in & that the Industar stops very close to the shutter assembly.
5. Finally, the older 50 Elmar does have a problem collapsing on some bodies, but the current Elmar does not, so it does not collapse as deep into the body as the older one does.
