Product Description
# Retina IIIc Schneider lens adapter to Praktica(M42)

This adapter enables to use "Retina IIIc Schneider lens" on SONY NEX, alpha 7 camera with Praktica(M42) mount adapter with focusing helicoid.

I have checked for rear lens on Retina IIIc with...
  - Retina-Xenon C f:2.0/50mm
  - Retina-Curtar-Xenon C f:5.6/35mm

* You have to remove lens from camera and modify always shutter opened.
* You need rear lens holding ring to adapt lens with this adapter. 
* Lens flange back is pretty strict. 3D print machine that Shapeways has been updating often return different results. I usually make lens adapter a bit over-inf. If you couldn't get infinity focus, you maybe get infinity focus by cutting or scraping it.
