The Leitz 180mm f/2 APO-Summicron-R is a fast medium-telephoto prime for the Leica R SLR system, mounting on bodies such as the R3 through R9. Its f/2 maximum aperture and APO designation place it among the specialist sports, wildlife and stage-photography lenses in the R line-up.

With only two recorded UK auction results, the price picture is thin: hammer prices have ranged from £2,083 in 2004 to £5,000 in 2013, giving a midpoint around £3,500. As of today in 2026 the lens remains scarce at saleroom level, and clean, fungus-free copies tend to sell for the upper end of that range, while well-used examples carry a clear discount; condition and completeness drive the value far more than vintage in this case, and what a 180mm f/2 APO-Summicron-R is worth at auction is highly dependent on glass quality.
