SIRUI Launches Swift Series of Ultra-Compact Autofocus Lenses
SIRUI has unveiled its new Swift series, which consists of ultra-compact, all-glass full-frame autofocus lenses. This series includes two models: the Swift 20mm f/2.4 and the Swift 40mm f/2.2.
Overview of the Swift Series
SIRUI has unveiled its new Swift series, which consists of ultra-compact, all-glass full-frame autofocus lenses. This series includes two models: the Swift 20mm f/2.4 and the Swift 40mm f/2.2. Both lenses are aimed at photographers and content creators who prioritize lightweight gear without compromising on optical quality.
Lens Specifications
The Swift 20mm f/2.4 offers an ultra-wide diagonal field of view of 91.5 degrees. It features an optical construction of 11 elements arranged in 9 groups, a minimum focusing distance of 0.2 meters, and a maximum magnification of 0.136. The lens weighs approximately 210 grams for both Sony E mount and L-mount.
The Swift 40mm f/2.2 provides a more natural perspective with its optical construction also consisting of 11 elements but in 8 groups. It has a minimum focusing distance of 0.4 meters and a maximum magnification of 0.14. This lens weighs about 210 grams for both Sony E mount and L-mount.
Build and Design
Both lenses in the Swift series are constructed entirely from glass, avoiding plastic optical elements. This choice contributes to their lightweight nature while maintaining optical integrity. Each lens includes an integrated manual aperture ring and features a nine-blade circular aperture for smooth out-of-focus transitions. They are equipped with STM autofocus motors, which are designed for quiet and responsive tracking, making them suitable for both still photography and video applications.
Filter Compatibility
To streamline the use of filters across both lenses, SIRUI has standardized the front filter thread to 58mm. This feature simplifies filter management for users who may opt to use both lenses in a dual-lens setup.
Mount Options and Pricing
SIRUI is launching the Swift lenses in both Sony E and L-mount versions, with additional support for Fujifilm X-mount also available. While further mount options are planned, the availability for Nikon Z has not yet been confirmed. Each lens is priced at $149, making them an accessible option for creators looking to build a lightweight primary kit or a secondary setup.
Conclusion
The SIRUI Swift series presents a practical solution for photographers and videographers seeking compact and lightweight lenses. With their all-glass construction and thoughtful design features, these lenses aim to meet the needs of modern content creators.
