The Light Lens Lab 35mm f2 "8 Element" Collapsible is an interesting lens: it's a recreation of the classic 8 Element Leica Summicron 35mm f2, but in a collapsible form factor that's exclusive to this lens. Except for the collapsing design, it's a pretty faithful recreation, made with leaded glass like the original (do not eat) and built from brass to a very high standard. Imaging is excellent. This black-paint lens has minor paint wear, with smooth focusing and clean glass. It's supplied in Leica thread mount with an M mount adapter, a matching hood, case, and box.
