The 10-element aperture has a special shape that is circular not only at the maximum aperture of F2.8, but also at F4 and F22. This allows photographers to take full advantage of the "ball blur" effect of point light sources and other objects. The included metal hood has a bayonet-type fitting and can be mounted in reverse when stored. It is convenient for carrying without compromising the compactness of the main body.
Manual Focusing for Reliable Focusing. The use of an all-metal helicoid unit machined and adjusted to a high degree of precision and high-quality grease that produces moderate torque enables focusing with a smooth operating feel. Subtle focusing adjustment is possible. The lens mount uses a VM mount compatible with the Leica M mount. The high-precision rangefinder-linked system allows for severe focusing near the maximum aperture. The camera has a generous image circle to accommodate a full-size 35mm-format camera. It also offers an extremely compact style compared to interchangeable lenses for SLR cameras. International Buyers - Please Note. Than you for your understanding.
