Cosina has officially announced the Voigtländer APO-Lanthar 90mm f/4 Close Focus, moving the lens from its CP+ 2026 prototype showing to a confirmed product for Leica M-mount. Shipping is expected to begin in August. The headline is physical. At 53mm in diameter, 54.8mm long, and 235 grams, this is a 90mm telephoto that behaves like a compact prime. That matters more on a rangefinder than on any other body: long M-mount lenses tend to intrude into the optical viewfinder, and a barrel this short keeps that intrusion minimal.
