Voigtländer's New Compact 90mm f/4 M-Mount Lens Set for August Launch

Precision Imaging, Unrivaled Portability: Discover the Voigtländer APO-Lanthar 90mm f/4 Close Focus Lens

Cosina's February Showcase and the Emergence of a New Optical Gem

Following a bustling CP+ 2026 exhibition where Cosina previewed an array of new Voigtländer lenses, the APO-Lanthar f/4 Close Focus VM-Mount lens has now been fully disclosed. This distinctive prime lens is slated for an August release, promising to deliver cutting-edge optical capabilities to photographers seeking both quality and convenience.

The Astonishingly Compact and Lightweight Design of the 90mm f/4 Lens

The Voigtländer APO-Lanthar 90mm f/4 Close Focus stands out for its remarkably small footprint and minimal weight. Typically, longer telephoto lenses, such as 90mm primes, can obstruct the rangefinder view on Leica M-Mount cameras. However, this new Voigtländer lens addresses this common challenge with its svelte dimensions, measuring just 53 millimeters (2.1 inches) in diameter and 54.8 millimeters (2.16 inches) in length. Weighing a mere 235 grams (8.3 ounces), it effortlessly accommodates 43mm filters.

Advanced Apochromatic Design for Superior Image Clarity

As its nomenclature suggests, the APO-Lanthar 90mm f/4 Close Focus incorporates an advanced apochromatic design. This sophisticated optical construction is meticulously engineered to eliminate axial chromatic aberrations, ensuring superior image clarity and color fidelity. Correcting chromatic aberration is a complex task, as it involves harmonizing various light wavelengths to converge at a single focal point.

Optical Configuration and Diaphragm Details

The lens's optical system comprises eight elements arranged in six distinct groups. A notable feature is the inclusion of abnormal partial dispersion glass in six of these elements, playing a crucial role in its apochromatic performance. Furthermore, the lens is equipped with a 10-bladed aperture diaphragm, contributing to smooth and aesthetically pleasing bokeh.

Exceptional Close-Focusing Capabilities for Detailed Shots

Beyond its compact form, a key highlight of the new Voigtländer APO-Lanthar 90mm f/4 is its remarkable close-focusing prowess. When utilizing a camera's live view function, the lens can achieve a minimum focusing distance of 0.5 meters (1.6 feet). It remains rangefinder-coupled down to 0.7 meters (2.3 feet), depending on the specific camera model. With a maximum magnification ratio of 0.28x, it offers impressive near-macro capabilities, an notable achievement for a VM-mount lens.

Versatile Compatibility with M-Mount and Mirrorless Systems

The lens's VM mount ensures native compatibility with Leica M-Mount cameras and other rangefinder systems sharing the M-mount. Its expansive full-frame image circle also facilitates seamless adaptation to a wide array of other cameras, including various full-frame mirrorless bodies, enhancing its versatility for diverse photographic applications.

Upcoming Availability and Initial Market Pricing

The Voigtländer APO-Lanthar 90mm f/4 Close Focus is scheduled to commence shipping in August. In Japan, the lens will be available at a price of 103,320 yen, which translates to approximately $640 at current exchange rates. Details regarding global pricing are expected to be announced in due course.
