Tip of the Week (#011) - Lens Coding

Lens coding. Normally a service provided by Leica for older Leica lenses and found on all new lenses. What if you use a Voigtländer, Zeiss or other lens? Or would rather not spend the money and time to get your Leica lens coded? The answer is simple, albeit temporary. Get a "D-Coder" ring from Match Technical or make your own template and use a Sharpie marker. Using the list of Leica lens codes, make your dots on the mount accordingly. Test on the camera, making sure "Lens detection" is set to "Auto." With use, the marks will wear off - they're quick and easy to re-apply.
