7Artisans Expands AF 40mm f/2.5 Lens to L-Mount and Z-Mount

7Artisans AF 40mm f/2.5 Expands to L-Mount and Z-Mount
7Artisans has extended its AF 40mm f/2.5 lens to L-Mount and Nikon Z-mount cameras, following its initial release for Sony E-mount. The lens, priced at $159, is designed for full-frame mirrorless systems and emphasizes portability with a weight of around 90 grams and a length of 40mm. The L-Mount and Z-Mount versions are expected to launch on August 6, as reported by Asobinet.
Design and Build
The lens retains its compact form across all mounts, with minor adjustments due to differing mount sizes. The Z-mount version may weigh slightly more due to its wider diameter, but the difference is negligible. The 40mm f/2.5 features a seven-element, six-group optical design and a nine-bladed aperture. 7Artisans describes it as a balance between portability and optical performance, though sample images suggest a stylized "bubble bokeh" effect that may not appeal to all photographers.
Autofocus and Compatibility
The lens uses an STM-based autofocus system, promising quiet and fast performance. It supports eye-detect and subject-tracking features on most Sony, Nikon, Panasonic, Sigma, and Leica mirrorless cameras. However, it is incompatible with the Sigma BF and Leica SL3-S, with no confirmation yet for the Leica SL3-P. A full compatibility list is available on 7Artisans' website.
Optical Performance and Tradeoffs
At $159, the lens prioritizes affordability and size over premium optical traits. The "bubble bokeh" effect is a deliberate choice, diverging from the smoother bokeh of higher-end lenses. The minimum focusing distance is 0.4 meters (1.3 feet), which limits close-up capabilities. Sample images from photographers like innamendelson and holbrookshots showcase its performance in real-world use.
Pricing and Availability
The E-mount version is already available for $159, with L-Mount and Z-Mount versions set to release on August 6. Pre-orders are not yet live, but the lenses are listed on 7Artisans' website. Photographers should verify compatibility before purchasing.
Who Should Consider This Lens?
The 7Artisans AF 40mm f/2.5 is ideal for photographers seeking a lightweight, affordable prime lens for full-frame systems. Its compact size makes it suitable for travel and street photography, though its optical quirks may not suit all styles. For those prioritizing portability and cost over absolute optical perfection, this lens is a compelling option.
