7Artisans 2814LMB 28mm ASPH Leica M Lens F1.4 M-mount

【Voltage Compatibility】 When using electrical appliances, please note that they are designed for Japanese voltage specifications (90-110V), so if you use them with a different voltage, it may cause a malfunction. 【Plug Type】 Our products use Japanese plug types (A or B type). Please use a conversion adapter if necessary. 【Important Note on Transformers and Adapters】 A transformer adjusts voltage to match your device’s requirements. A conversion adapter only changes the plug shape and does not adjust voltage. Using only a conversion adapter without a transformer may result in damage to the product. 【Liability】 We are not responsible for malfunctions or damages caused by improper use, such as operating the product without a transformer. A Leica M-mount lens with a wide-angle focal length of 28mm and a very bright aperture value of f1.4, compatible with rangefinder coupling. The lens is made up of 11 elements in 9 groups, two ED (extra-low dispersion) glass elements, and three high-refractive low-dispersion glass elements, which effectively corrects various aberrations and allows for high resolution even in the peripheral areas. In addition, the lens is compact thanks to the use of one ASPH (aspherical lens) with a different curvature from the spherical lens. This high-performance lens can be used even in low-light conditions, and can produce images that make the most of the bokeh despite its wide angle. The user can fine-tune the settings and focus by using the included rangefinder coupling adjustment chart.
