Leica M9 and Lomo T-43 40mm lens - No 4 of 4
This lens - on the right - from a Cosmic or Smena Symbol or 8M has been mounted in a 39mm Zenit mount from the 1960's Industar-50. So it will work in a Leica but is not range finder coupled. Also the focus scale is for a 50mm lens. So I had to experiment to see where it focussed and so on.
The black lens on the left is from a Zenit or Zenit 3M and should show how the lower half was used with a bit of tubing and the LOMO lenses optical group to give the correct registration.
For speed I shall probably mark the hybrid lens for zone focussing at f/5.6...
You can see the lens in action and mounted on a Leica M9 in the previous three pictures.
