Contax G35 f/2 to Leica M Conversion
- Non-Destructive Conversion: When we convert the original Contax G35 lens for Leica M mount, we will not damage the lenses. It feels as good as the original Contax lens after conversion.
- Good User Experience: The way of using this converted lens is just like using Leica Summicron 35mm/2.0. With unsurpassed optics and images, you won't feel much difference compared to Leica lenses when you use it on Leica M.
- Easy to DIY: If you have a Contax G35 lens, it is easy to assemble the original Contax optical lens group into our converted helicoid. You can recover Contax G35 if you do not want to play.
- Distinctive Patina: This lens is fun and silmilar to Leica MP "correspondent". You can create a distinctive patina by sand paper, which would usually point to many years of constant use. To achieve this look, every lens can be ‘aged’ entirely by hand to create absolutely unique individual products.
