☆ This is a Pentax Takumar 135mm F3.5 manual focus telephoto prime lens. ☆ As a telephoto lens, it's bright at F3.5, and the bokeh is smooth and beautiful when wide open! It's a lens that resolves sharply when stopped down. ☆ You can also use it with digital cameras (mirrorless) by attaching a mount adapter compatible with various manufacturers. The focal length is approximately 202mm in full-frame equivalent, making it a very bright telephoto lens. ☆ The aperture is preset, and the lens diameter is a mere 46mm, making it extremely rare, with very few search results on Mercari and the internet. ☆ The lens hood is essential for preventing flare and ghosting. I've included a genuine high-quality metal hood, made possible by a 46-49mm step-up ring. ☆ It's compact and lightweight for an F3.5 lens, making it highly portable. ☆ Sample photos were taken with a Fujifilm X-H1. ◇ No need to ask to purchase, and please refrain from price negotiations. 【Product Overview】568134 　・Lens Mount: M42 　(Since there is no M42 mount setting on Mercari, I have selected K mount) 　・Full-frame compatible (202.5mm on APS-C cameras) 　・8 aperture blades 　・Minimum focusing distance: 2m 　・Weight: 327g 【Operation】 　・Focus: Fully functional 　・Aperture blades: Fully functional 　・Focus ring: Appropriate feel 　・Preset ring: Appropriate click feel 　・Aperture ring: Appropriate feel 【Optics】Optically beautiful 　・Clear, with excellent light transmission. 　・No scratches, mold, fogging, or balsam separation on the lens. 　・Only a very small amount of dust, which does not affect the photos at all. 【Appearance】Superb condition, photos of the entire outer circumference are posted 　・Beautiful, with no scratches or marks. 　・No dents or stickiness. 【Accessories】 　・Genuine high-quality metal hood, in superb condition 　・Step-up ring 46-49mm (for the hood) 　・Unknown manufacturer's hood cap 　・SIGMA rear cap 　・Kenko SKYLIGHT filter Φ46mm ◇ If there is a significant oversight that affects the value of the product, ★please send a message without rating the item★.
