True. In the end I sold it because the collapsibleness got in the way with my shooting, too often it wasn't extended...
And, it was perfect on an M camera, but the lens mount was too wide for a Barnack, making it look misplaced on that...
Now, I have the Color-Skopar 50/2.5 too, it's as sharp as the L-Hex to my eye, and fits a Barnack much better. Just as big as the collapsed L-Hex but always ready to shoot.
