Leica Summicron-M 28mm f/2 ASPH. - Leica M Mount

The Leica Summicron-M 28mm f/2 ASPH. is a fast wide-angle lens that offers a significant aperture advantage over the Elmarit-M variant. Its optical design effectively suppresses distortions and aberrations, providing high resolution across the frame. The f/2 aperture allows for effective subject isolation and improved performance in low-light environments, making it a favourite for environmental portraiture and reportage. Inspect the lens for any signs of 'wobble' in the front barrel, which can occasionally occur with heavy use. SDS tests the tactile feedback of the aperture ring and ensures the focusing tab is securely attached. The glass should be checked for internal dust, and the lens hood—which is often a large, rectangular metal design—should be checked for dents or threading issues that might affect filter attachment.
