Meyer Optik Trioplan 100mm F2.8 Old Lens. Exakta mount. Exakta models are easy to adapt to mirrorless cameras, and are a better value than M42 mounts, so they are recommended. Released in 1936. This old lens became famous for its ability to capture bubble bokeh and soap bubble bokeh with emphasized outlines. This "Soap bubble bokeh" is produced by a triplet configuration of three lenses, and while other lenses also have this characteristic, none can create bokeh as clearly defined as this lens. Therefore, in recent years, prices have soared, and it has become difficult to find a beautiful item for less than tens of thousands of yen. I have prepared some sample photos taken with this lens. I think I was able to capture the characteristics well in this photo of a cat, which I chose for the cover. The image of a string of light rings in the background is unique to the Trioplan. I hope you enjoy the atmosphere of an old lens. When you have this lens, you will naturally find yourself searching for angles that produce bubble bokeh. It's not just any light; the key is to use artificial light sources that are not too strong in the background bokeh. Condition: The exterior shows no noticeable scratches from use. The optics are not exactly moldy or cloudy, but there are fine cleaning scratches. As you can see in the sample photos, there is no whitening even on a sunny day, so I don't think there are any major problems, but because of that, it will be listed at a slightly lower price, so if you are looking for a working Trioplan, this is your chance. Please consider it. Condition: Used item, operation confirmed. Exterior: Scratches from use, no noticeable dents. Optics: No mold or clouding, but there are fine cleaning scratches throughout.
