Cosina has officially launched its latest offering, the Voigtländer Septon 40mm f/2 Aspherical prime lens, tailored for contemporary full-frame mirrorless camera systems, specifically the Sony E-mount and Nikon Z-mount. This lens is engineered to provide superior optical performance in a remarkably compact and stylish form factor, catering to photographers seeking both quality and portability.
The newly unveiled Voigtländer Septon 40mm f/2 Aspherical lens is a testament to Cosina's commitment to precision engineering. It integrates an Orthometer optical design, which is crucial for delivering exceptional image clarity and sharpness across the entire frame, even when shooting with a wide-open aperture. This design also effectively mitigates chromatic aberrations, ensuring that images are rendered with accurate colors and fine detail. Despite the internal optical similarity, the external aesthetics and physical dimensions of the E-mount and Z-mount variants differ. The E-mount version is notably lighter and more compact, weighing approximately 165 grams and measuring just 30 millimeters in length, making it an incredibly portable option for Sony users. In contrast, the Nikon Z-mount iteration is slightly larger and heavier, at 205 grams and 32 millimeters long, and features a distinct scalloped focus ring, setting it apart visually from its E-mount counterpart, which sports a diamond-knurled design. Both versions accommodate 52mm front filters, adding to their versatility.
The 40mm focal length of the lens offers a natural perspective, making it suitable for a broad spectrum of photographic applications. Whether capturing dynamic street scenes, expansive landscapes, or intimate portraits, this lens provides a versatile field of view. Its ability to focus as closely as 0.3 meters (0.98 feet) allows for a maximum magnification of 1:5.3, expanding creative possibilities, though it's not intended for dedicated macro photography. As a manual focus lens, the tactile experience is paramount, and Cosina has ensured a finely tuned focusing mechanism. The all-metal helicoid unit is precision-machined and adjusted to provide smooth, consistent focus operation with optimal torque, a feature that aligns with the positive experiences reported by users of previous Cosina Voigtländer lenses. This attention to detail in mechanical design enhances the user's control and precision during manual focusing.
The introduction of the Voigtländer Septon 40mm f/2 Aspherical lens reinforces Cosina's dedication to producing high-quality manual prime lenses for mirrorless camera systems. With its advanced optical design, compact form factor, and smooth manual focus operation, it is poised to be a valuable tool for photographers who prioritize image quality and a hands-on shooting experience. The lens is expected to hit the market in March, offering an appealing option for Sony E and Nikon Z users.
