Skyllaney Opto-Mechanics is able to convert non-rangefinder lenses to become LTM/ M mount lenses with full RF coupling using a variety of methods.

Donor helicoids can be used for a wide variety of lens conversions. They can be sourced from vintage lenses like Jupiter Zorki series, Canon LTM series, Nippon Kogaku LTM series, even Leica LTM and M series.
Often, the optics inside these lenses may have severe issues that make their repair non cost-effective.  However, the good working helicoids and lens mechanics can be re-used to convert other non-rangefinder lenses through a series of new conversion parts and existing part modifications.
Skyllaney Opton-Mechanics has in-house lathes and CNC machines that are solely dedicated to the fabrication and modification of mechanical lens parts to facilitate the creation of custom rangefinder lenses.

Below is a list of just some of the non-rangefinder lenses we have converted LTM/ M bayonet mount with full RF coupling:
135mm Sonnar, 90mm Sonnar, 85mm Sonnar, 58mm Biotar, CY 50mm Planar, 50mm Summilux-R, 50mm Summicron-R, 50mm Sonnar CRF, 50mm Tessar, 50mm Nikkor-SC, 40mm Rollei Sonnar, 40mm Biotar, 38mm Sonnar, 35mm Biogon, 35mm Wollensak Raptar, 35mm CG Planar, 35mm Biometar, 35mm Tessar, 35mm W-Nikkor, 28mm CG Biogon, 28mm Tessar, 21mm Biogon

Contax G conversions:

We are working on converting the Contax G 21mm and 28mm Biogons using Omnar. These lenses require new aperture control assemblies designed for the optical block. Conversions for these lenses will be available at a later date. You can contact us to be added to a waiting list.

CZ 50mm f/1.4 Planar:

For specific information about CZ 50mm f/1.4 Planar conversions, follow the link below:

The cost of the conversion varies depending on the lens and work involved. Please contact us if you are interested in this service.

The conversion process is an ideal time to have the lens professionally repainted in a variety of finishes, like Black Chrome, Nickel, Gloss Black, Antique, Silver Chrome and a near infinite selection of cerakote colours. We use the services of Camerakote for lens repaint, please see a small selection of available finishes in the image below.

Below are some examples of a small selection of our conversions:
