Asahi Pentax 17mm f/4
The Asahi Pentax 17mm f/4 SMC Takumar is an ultra-wide fisheye prime for the M42 screw mount, dating from the Super-Multi-Coated Takumar era of the early 1970s. It was designed to deliver an extreme angle of view on 35mm SLR bodies and is commonly paired with Spotmatic-generation Pentax cameras, though it adapts readily to modern mirrorless systems.
UK auction activity for this lens is thin: the three hammer results on file, all from 25 November 2025, each sold for £90, giving an identical low, high and median of £90 at saleroom level. Because these figures are wholesale auction hammers (excluding commissions), retail dealer asking prices in 2026 typically sit meaningfully above this band, and clean, haze-free copies with original caps and case tend to command the upper end of what the fisheye Takumar is worth today. Collector demand is driven by the SMC coating and the lens's reputation as a characterful specialist optic rather than an everyday wide.

Frequently asked questions
What is a Pentax 17mm f/4 SMC Takumar worth at UK auction?
Based on the limited sales on file, the lens has a hammer value of around £90, with all three recorded UK auction results landing at exactly that price.
How much does a 17mm f/4 SMC Takumar sell for today?
At current saleroom level the lens sells for about £90 as a hammer price, so expect retail dealer prices in 2026 to sit above that once commissions, warranty and margin are added.
Is the price the same for every copy?
The three logged sales all cleared at the same £90 figure, but condition factors such as fungus, haze, oil on the blades and coating scratches can push individual copies above or below this typical value.
What mount does this fisheye Takumar use?
It is an M42 screw-mount lens from the SMC Takumar generation, so it fits Pentax Spotmatic-era bodies directly and modern mirrorless cameras via an inexpensive M42 adapter.
