The Leitz 350mm f/4.8 Telyt-R is a long telephoto prime for the Leica R SLR system, designed for wildlife, sports and distant subject work on R-series bodies such as the R3 through R9. As an R-mount lens it will not fit M-mount rangefinder cameras, and it sits in the super-telephoto tier of the Leitz reflex catalogue.

Recent UK auction hammer results for the 350mm Telyt-R have been modest: the two tracked sales closed at £130 and £312, giving a median around £221 at saleroom level (wholesale, before buyer's and seller's commission). As of 2026 these figures suggest the lens is worth considerably less than its shorter R-mount stablemates, and the wide spread between the two hammer prices indicates that condition and completeness heavily influence what a copy sells for today.
