Leica Summilux-M 50mm f/1.4 v1 (E43) Review: The Poet’s First Light—Where Vintage Flaws Dance with Unreplicable Soul

The Birth of a Legend

Born in 1959 as Leica’s answer to postwar optimism, the Summilux 50mm f/1.4 v1 (E43) straddles eras like Berlin’s fractured Wall. Its 7-element design—an evolution of the Summarit f/1.5’s dreamy haze—offers photographers a foot in two worlds: the romantic swirl of 1950s optics and the crisp demands of modern film stocks. At 1,200–1,200–1,800 (well-loved), it whispers, “Character over clinical perfection.”


Optical

  1. Aperture Alchemy
    • f/1.4 Reality: Center sharpness cuts Tri-X like a scalpel; edges dissolve into watercolor abstraction
    • Stopped-Down Zen: f/2.8 transforms into Ansel Adams’ disciplined disciple
  2. Bokeh Ballet
    • Signature Swirl: Oval highlights pirouette like drunken ballerinas
    • V2 Comparison: Later ASPH versions trade chaos for choreography
  3. Flare Philosophy
    • Single-Coated Soul: Sunstars bloom like dandelions in a hurricane
    • ND Filter Hack: Slap on a 3-stop ND for midday f/1.4 street sorcery

The v1 Paradox

Leica’s open secret: This lens’ “flaws” are its scripture.

  • Edge Softness: Masks digital sensors’ clinical gaze
  • Focus Shift: f/1.4 to f/2.8 requires Zen acceptance (or zone focusing)
  • M3 Synergy: Its 1959 soulmates Barnack’s masterpiece flawlessly

Who Should Embrace This Relic?

Film Alchemists: Brewing magic in silver halide
Portrait Poets: Who see pores as landscapes
Leica Purists: Collecting stories, not MTF charts

Avoid If: You pixel-peep or fear focus shift.


Final Verdict: The Beautiful Flaw

The Summilux v1 E43 is optical jazz—improvised, raw, and unrepeatable. For the price of a weekend in Paris, you gain:

  • 80% vintage Summarit mystique + 50% modern practicality
  • Proof that “sharpness” is a capitalist conspiracy
  • Permission to fall in love with photography again
