The Meike 85 mm f/1.8 AF STM Pro L-Mount lens is a prime lens with a portrait length, specifically designed for Leica L-Mount DSLR systems with a full-frame sensor. With its 85 mm focal length and a bright maximum aperture of f/1.8, this lens excels in subject positioning and low-light performance, making it particularly suitable for portrait photography and close-ups. The lightweight telephoto focal length provides natural compression while maintaining a comfortable working distance from the subject. The lens features a stepper motor autofocus system that enables fast and precise focusing, complemented by a minimum focus distance of 85 cm for detailed close-up shots. The optical design includes a rounded nine-blade diaphragm that produces soft, pleasing bokeh in out-of-focus areas, enhancing both image aesthetics and subject positioning. The lens delivers consistent performance under various lighting conditions, with the f/1.8 aperture allowing for creative control over depth of field and exposure settings. The build quality meets professional standards with durable construction materials and precise manufacturing tolerances. The lens measures approximately 78 mm in diameter and 90 mm in length, weighing around 420 g, providing balanced handling on compatible camera bodies. The filter thread size is 67 mm for standard filter accessories. This lens represents a successor model in Meike's professional lens lineup, offering reliable performance for photographers seeking high-quality optics for portrait, event, and creative photography applications. Compatibility is confirmed with Leica L-Mount DSLRs with full-frame sensors, and users should verify specific camera model compatibility for optimal performance.
