Leica Visoflex Helicoid OUEPO 16462, black model. *Lens not included, shown for example purposes. This is an attachment part for mounting the mid-telephoto Summicron 90mm F2 lens to a Visoflex. With the 90mm focal length and a large aperture of F2, this high-resolution lens allows you to enjoy the unparalleled focus accuracy of the Visoflex; it's truly a forbidden ring! It's easy to use. You can easily remove the lens head from the standard barrel of the Summicron 90mm. Simply insert this part between the Visoflex 2 or Visoflex 3 and the lens head. I'm offering this at a lower price to promote the Visoflex, so please consider it. Main compatible lenses: Summicron 90mm F2 Elmarit 135mm F2.8 Condition: Beautiful inside and out, smooth operation. *Please consult if using a cheap Chinese mount for mirrorless conversion, as interference may occur. *Evaluations are subjective.
