Leica Summilux-M 35mm f/1.4 - Leica M Mount

The Summilux-M 35mm f/1.4, specifically the pre-ASPH versions, is famed for its compact size and unique 'glow' when shot wide open at f/1.4. Often referred to as the 'Steel Rim' (early versions) or the 'Pre-ASPH', it is a classic tool for low-light photography where a compact kit is essential. While it lacks the clinical sharpness of modern ASPH versions, it is highly sought after for its characterful, vintage aesthetic. When assessing a used model, check for internal haze and cleaning marks on the soft coatings of the front element, which are common on older examples. SDS ensures the aperture blades are clean and the focus mechanism is not stiff due to dried grease. In the earliest 'Steel Rim' versions, check the condition of the dedicated OLLUX hood if included. Ensure the rangefinder coupling is accurate, as these lenses can be sensitive to calibration.
