Asahi Pentax 20mm f/4.5 Super-Takumar
The Asahi Pentax 20mm f/4.5 Super-Takumar is an ultra-wide-angle prime lens made for the M42 screw-mount system. It dates from the Super-Takumar era of the late 1960s to early 1970s and was designed for general wide-angle work on Pentax Spotmatic-series 35mm SLRs.
Sales data for this lens is thin, but a clean copy sold at UK auction in late 2025 for £90 at the hammer, giving a current reference value in that region as of today. Because only a single recent saleroom result is available, the price band is uncertain and condition-sensitive examples can move materially either side of that figure. Buyers should treat £90 as an indicative wholesale-level data point rather than a settled market price, and watch for fresh hammer results before committing.

Frequently asked questions
What is a Pentax 20mm f/4.5 Super-Takumar worth today?
Based on a single UK auction hammer result from late 2025, a clean example is worth around £90, though limited data means real-world prices can vary with condition.
How much does a 20mm f/4.5 Super-Takumar sell for at auction?
The most recent saleroom hammer price we have on record is £90, which is the best available reference for the lens's current wholesale value.
Will it fit a modern camera?
The lens uses the M42 screw mount, so it adapts readily to most mirrorless bodies via an inexpensive M42 adapter, which supports its ongoing price on the used market.
What should I check before buying one?
Prioritise glass clarity (no fungus or haze), clean and snappy aperture blades, smooth focus, and undamaged M42 threads, as these factors drive what the lens is worth.
