Resources

Mike Butkus has spent decades scanning and freely sharing camera instruction manuals, and his Leica section covers the full R-mount range. If you have acquired an R-body without its original manual — or simply want to understand a particular function in more depth — this is the first place to look. Manuals are available as PDF downloads at no charge, though donations to support the site are encouraged.

Based in Germany, Paepke Fototechnik is a specialist repair and maintenance workshop with extensive experience servicing Leica cameras, including the full R-mount range. Services include CLA (clean, lubricate, adjust), shutter calibration, light seal replacement, and general restoration. English-language service information is available on their website, making them accessible to international customers shipping cameras for service.

One of the largest and most active online communities dedicated to Leica cameras, with dedicated sections covering the R-mount system. A valuable resource for buying advice, technical questions, user reviews, and the kind of accumulated practical knowledge that only comes from a community of long-term enthusiasts. The forum covers all Leica systems but has a strong R-mount following, and its search function is an excellent first stop for any technical query about a specific body or lens.
