The Summicron-M 50mm v4 is the 'bokeh' version — the Version 4 optical formula is valued for its rendering wide open, with slightly smoother out-of-focus transitions than the Version 5 (current). Mechanically robust. Distinguish from v1 (collapsible), v2 (dual-range), v3 (7-element), and v5 (current) by optical performance and value.
On the used market the Summicron-M 50mm v4 is a sought-after classic Leica standard prime. Condition checks: f/2 elements and aperture blades, focus smoothness. Leica M mount.
