Leica Elmar 9cm F4 Collapsible Old Lens Leica M mount. Easily convertible to a mirrorless mount. Released in 1954. The collapsible lens is perhaps one of the dreams of old lens fans who appreciate the form. This lens is a giant of collapsible lenses, which can be said to be at the pinnacle. When collapsed, it's about the size of a standard lens, but when extended, it stretches about 4cm, reaching a length of 8cm. The thought that such a mechanism is contained within this makes me so excited. It's not just about the appearance; the depiction also doesn't betray the taste that one seeks in an old lens. The specifications of a medium telephoto lens with F4 allow you to shoot with confidence even at the widest aperture. As a type, it's high-resolution and sharp, typical of Leica, but it's also possible to create soft flares if you capture the light. I have prepared some sample photos using this lens. This is my favorite lens, which I've been gradually testing since midsummer. With this lens, you can create a stunning rainbow, like the one on the cover, in a straight line from a light source almost directly from the side. On the other hand, near the light source, you can produce two different types of ghosts, like a shower of light, as seen in the second photo. It's attractive just to be able to enjoy two unique depictions. It's a type that tends to flare when there's a light source, but as a result, the rainbow appears more vivid than usual. Shooting in the same direction as the light is also mellow. It's a lens with a strong personality, but you can still take normal, good photos with it. The exterior has fine scratches on the easily scratched focus ring, a shiny lens barrel, and is in good condition without any noticeable dents. The optics have no mold or haze, but there are fine cleaning scratches on the front element, and light bleeding, which is the reason for the tendency to flare in backlight. I highly recommend it to those who like the atmosphere of the sample photos. Includes the original front cap. Condition: Two types of ghosts are unique! It's a type that tends to flare.
