{"overview":"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.","market_narrative":"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.","buying_guide":"Given the size of the front group, inspect carefully for fungus and haze in the internal elements and check for any signs of separation along cemented groups. Work the long zoom and focus travels through their full range to confirm they are smooth rather than stiff or gritty, look for oil migration onto the aperture blades, and examine the multi-coating for cleaning marks or scratches. Confirm the M42 mount threads are clean and that the built-in tripod collar rotates and locks properly, as a damaged collar is awkward to replace.","specs":"Key specifications from the supplied data: 135-600mm focal range, maximum aperture f\/6.7, M42 screw mount, and Asahi's Super-Multi-Coated (SMC) Takumar optical treatment.","faq":[{"q":"What is a Super-Multi-Coated Takumar Zoom 135-600mm f\/6.7 worth today?","a":"The single verified UK auction hammer result on record is £362 in 2022, so that figure is the best available reference for the lens's wholesale value, with clean complete copies likely to price above it."},{"q":"How much does a Takumar 135-600mm f\/6.7 sell for at auction?","a":"Sales history is limited to one UK saleroom result of £362, a hammer price that excludes buyer's and seller's commission."},{"q":"What mount does the 135-600mm Takumar use?","a":"It uses the M42 x 1mm screw mount common to the Takumar lens line, so it can be adapted to most modern mirrorless bodies via an M42 adapter."},{"q":"Is the price of this Takumar zoom affected by condition?","a":"Yes — fungus, haze, oil on the aperture blades, coating scratches and a missing tripod collar or case will all reduce value significantly against the £362 reference price."}],"confidence":35,"reasoning":"Only one verified sales record and no SPECS or variant facts beyond model name, so confidence is capped low per rule 8."}
