The Asahi Pentax Super-Multi-Coated Takumar Zoom 135-600mm f/6.7 is a long-range telephoto zoom built for the M42 screw mount during the Takumar era of the late 1960s and 1970s. Designed for wildlife, sports and distant subject work, it carries Asahi's Super-Multi-Coated optics and is one of the longest reaching zooms ever produced under the Takumar name.

Auction data for this lens is thin: the only verified UK saleroom result on file is a single hammer price of £362 from March 2022, which sets the available reference for what a complete copy sells for at wholesale auction level today. With just one data point, condition, completeness of the original tripod collar and case, and clarity of the front element will swing the price materially either way, and a clean, fungus-free example would be expected to value above that figure while a hazy or damaged copy is worth less.
