Leica R Primes: Elmarit | Summilux

7 primes 19 – 135mm T1.5 – T2.9 PL
Leica R primes are revered for their creamy, flattering image.
Wide open, they are well-corrected and reasonably sharp, yet have a gentleness in how they draw: sharp but forgiving. They flare beautifully: a pleasant bloom and slight veiling that gives images a romantic touch. Focus fall-off is very smooth, and out-of-focus areas melt away with minimal nervousness. Consistently praised for round, creamy bokeh with background highlights blending softly, a near “Cooke-like” quality.

Sharp yet forgiving. Romantic highlights.

Technical
Heritage
Origin
From Leitz (Leica) Wetzlar’s R-series SLR lenses (1960s–80s), the German optical heritage that defined still-photography “glow” for half a century. “Summilux” denotes f/1.4 designs, “Elmarit” denotes f/2.8.
Filmography
Long beloved by still photographers: Salgado, Ferdinando Scianna, and countless reportage and editorial shooters built careers on Leica R glass. Leica stopped making R lenses in 2009; their cinema legacy lives on through rehoused sets like this.
Build
G.L. Optics did a full Mk III/IV rehousing to turn the R primes into true cinema lenses. Close focus dramatically improved over original Leica specs: the 28mm now focuses at just 8 inches. Most of the set is under 1.5kg (0.9–1.9kg per lens), which makes it ideal for handheld and gimbal work. PL mount, matched fronts, 0.8M gears.
