The Mandler Miracle
In Leica’s constellation of 50mm lenses, the Summicron-M 50mm f/2 v4 (1979–present) shines as Polaris—unchanging, reliable, and eternally luminous. Designed by the legendary Walter Mandler in 1979 and still in production today, this 240g aluminum oracle blends Bauhaus pragmatism with optical sorcery. Priced at 1,800–1,800–2,500 (used), it’s the “gateway drug” to Leica addiction—and often the final destination.
Design: Mechanical Poetry
- Chassis Choreography
- Body: Anodized aluminum (black) or brass (silver)—dense as a haiku, light as a sonnet
- Focus Throw: 180° from 0.7m to ∞—street photographer’s waltz
- Aesthetic: Three flavors—Tiger Claw, Crescent Moon, Built-in Hood—all singing Mandler’s tune
- Generational Nuance
- Tiger Claw (v4): Tactile nubs for blind focus—samurai precision
- Crescent Moon (v4): Silky slide of nickel-brass—calligrapher’s grace
- Modern (v5): Flattened hood for minimalist purity (but loses tactile soul)

The Mandler Paradox
Leica’s open secret: This lens’ perfection killed its successors.
- f/2 Magic: Depth rendering even APO can’t replicate
- Blind Focus Mastery: 1.7m = street photography’s sweet spot (25% success rate = 100% joy)
- Filter Zen: 39mm threads unite with 35mm Summicron siblings
Generational Wars
- v1 (1953): Collapsible relic—cheap thrill with radioactive glass
- v2 (1956): Rigid/DR—collector’s mirage (fungus included)
- v3 (1969): Aluminum abomination—Leica’s midlife crisis
- v4/v5 (1979+): Mandler’s masterpiece—optical immortality

Aluminum psalm,
Fifty millimeters hum—
Light bends to old gods.
Epilogue: The i50mm Paradox
We rage against rising prices yet fuel the fire. The Summicron 50mm f/2 v4—once 1,200,now1,200,now2,500—mocks our hypocrisy. Yet in its brass heart, it understands: true love is irrational. As the Chinese collectors say: “玩镜头不归路”—there’s no return from the lens rabbit hole. But with this Mandler masterpiece, you might finally stop digging.
