Leica Summicron First Generation 5cm F2 Collapsible L39 screw mount. Easily adaptable to M mount and mirrorless camera mounts. Released in 1953. Arguably the most famous camera lens in the world, a legendary lens of the 20th century with many anecdotes. It set the standard for 50mm F2 lenses, and its performance was so high that its resolution could not be measured. It's a high-performance lens that transcends time, capable of delivering excellent results even when used with modern mirrorless cameras. This collapsible model is particularly known for its high central resolution. Highly recommended for those who are particular about portrait compositions. I have prepared some sample photos taken with this lens. The first impression is brightness, with high contrast and good color reproduction. As a Summicron, it's not the sharpest type, but rather has a soft impression, and is sensitive to light, especially in backlight, where it produces quite dramatic flares and ghosts. The light that runs diagonally is particularly unique to this lens. However, it performs well in direct light, allowing you to take normal photos like test shots. The product shots look too good. While not to the extent of mold or haze, there is damage to the front element coating, cleaning scratches (common in the past), and point damage to the coating on the third element. The rear element group is clean. Slightly over-infinity, with the focus slightly beyond infinity, making it difficult to use with a rangefinder, so it's best to use it with a mirrorless camera or live view shooting. The operation itself is smooth. This is a bargain due to the issues. Condition: SALE with issues! A lens that produces large flares and ghosts. Appearance: Clean with minor scratches from use, no noticeable scratches. Optics: Front element coating damage, cleaning scratches. Operation: Slightly over-infinity, suitable for mirrorless cameras. Accessories: Front and rear caps. Stored in a dehumidified storage. #Leica #Summicron #OldLens #LegendaryLens 9498 *All used lenses on sale have been tested with actual photos! *Evaluations are subjective.
