7Artisans is set to broaden the availability of its highly anticipated AF 40mm f/2.5 full-frame prime lens, bringing this compact and cost-effective optic to users of L-Mount and Nikon Z-mount mirrorless camera systems. This move follows its initial release for Sony E-mount cameras, maintaining the lens's signature lightweight design and competitive price point.
Reportedly launching tomorrow, the L and Z-mount iterations of the 7Artisans AF 40mm f/2.5 are anticipated to deliver an experience consistent with the Sony E-mount version. Minor adjustments to the physical design will accommodate the differing lens mount diameters, but the core performance characteristics are expected to remain unchanged. The original E-mount model weighs a mere 90 grams (approximately 3.2 ounces), and the new versions are expected to be similarly featherlight, with only subtle weight increases, particularly for the wider Z-mount. All versions will share a compact length of about 40 millimeters (under 1.6 inches), positioning them as exceptionally portable options for full-frame photography.
The optical construction of this lens comprises seven elements arranged in six groups, complemented by a nine-bladed aperture. 7Artisans highlights its commitment to a harmonious blend of portability and optical quality. While marketing rhetoric often emphasizes such attributes, early impressions from sample images suggest a commendable performance, especially considering the lens's accessible $159 price. A notable characteristic of the 7Artisans 40mm f/2.5 is its 'bubble bokeh,' a stylized out-of-focus effect that some photographers will undoubtedly appreciate for its unique aesthetic, while others may find it less desirable than a smoother, more conventional bokeh.
Equipped with an STM (stepping motor) autofocus system, the lens promises swift and silent focusing capabilities. This technology ensures compatibility with advanced camera features such as eye-detection and subject-tracking across a wide array of mirrorless cameras from brands like Sony, Nikon, Panasonic, Sigma, and Leica. The minimum focusing distance of the lens is 0.4 meters (1.3 feet), which, while not exceptionally close, is adequate for many everyday shooting scenarios. However, it is crucial for potential buyers to verify compatibility with their specific camera models, as 7Artisans has indicated that the AF 40mm f/2.5 is not compatible with certain models, including the Sigma BF and Leica SL3-S. Comprehensive compatibility information is available on the manufacturer's website, urging photographers to confirm device support before making a purchase.
The 7Artisans AF 40mm f/2.5 lens is currently available for E-mount systems at $159. The L-Mount and Z-mount versions are slated for release on August 6th and are already listed on the 7Artisans website, awaiting their official availability for purchase. This expansion offers a compelling, budget-friendly option for full-frame mirrorless camera users seeking a lightweight and capable prime lens.
