Spec Notes
Cosina: 7 groups 9 elements; 10 blades; Minimum Focus 0.5m, but the RANGEFINDER only couples to 0.7m — below that it is a live-view lens. A NEW optical design, not the 1999 L39 Ultron (8el/6gr). Released 2015-08, discontinued 2019-11. The catalog previously recorded 7el/5gr, 166g, filter 43mm, 0.7m, year 2000 — matching neither this lens nor the L39 original. Those numbers were invented outright.

Weight Basis
Black 238g (aluminium barrel). The SILVER variant is BRASS and weighs 330g — a separate catalog row, because the weight difference is real (39%), not cosmetic.
