Helios 44M-6 58mm f/2 (M42)

The Helios 44M-6 — the later, multicoated version of the legendary Soviet 58mm f/2. Derived from the Zeiss Biotar, it’s beloved for its dreamy, swirling bokeh wide open, and the multicoating adds a little more contrast and flare resistance. M42 screw mount, so it drops onto film SLRs and adapts to almost any mirrorless body.
