Voigtländer is the oldest name in photography. The original Voigtländer optical company was founded in 1756 and has been producing groundbreaking photography equipment since. They created the fastest optical lens in the world in 1840, the original Petzval lens, which was a screaming fast f/3.7. Ok, screaming fast for 1840. They also created the first all-metal daguerreotype camera in 1841. That legacy of solid metal build and ultra-fast optics is realized today in the lineup of ultra-fast lenses for the Micro 4/3 system.
Today, the Voigtländer name is owned by Cosina in Japan, but they continue the legacy by producing outstanding optics for a range of SLRs, rangefinders and now mirrorless cameras. The lens we’re looking at today completes the trinity of ultra-fast primes for the Micro 4/3 mount. In 2010, Voigtländer made waves by introducing the 25mm f/0.95 Nokton. They followed that by creating a 35mm equivalent lens in the 17.5mm f/0.95 Nokton (reviewed here). Now, in 2013, they complete the trinity with a portrait length lens while maintaining that ultra-fast f/0.95 aperture in the Nokton 42.5mm f/0.95.
