Asahi Pentax Pentax SFX
The Pentax SFX is a 35mm autofocus single-lens reflex camera introduced by Asahi Pentax in the late 1980s. It was positioned as an enthusiast SLR built around the Pentax KAF bayonet mount and was among the earliest SLRs to integrate a built-in TTL flash into the prism housing.
Sales data for the Pentax SFX is extremely thin, so a reliable price band is hard to draw today; the single UK auction-hammer result on file sold for £1,200 in June 2025, which is well above the level a typical user-grade body would be expected to fetch at saleroom level. Until more results accumulate, treat that figure as an outlier rather than a guide to what the camera is worth, and judge the value of any individual example on cosmetic condition, working electronics, and whether a lens is included.

Sales History
Prices shown are realised prices — auction results and completed eBay sales, never asking prices. Most saleroom figures are hammer prices, before commission; some houses publish a premium-inclusive figure, and we do not adjust for condition. Dealer and retail asking prices are typically higher.

Frequently asked questions
What is a Pentax SFX worth today?
With only one UK auction-hammer record on file, at £1,200 in 2025, there is not yet enough data to quote a confident market value, and that single result sits above what a typical working body would be expected to sell for.
How much does a Pentax SFX sell for at UK auction?
The only logged hammer price is £1,200, but a single sale is not a reliable guide; buyers should compare current listings of comparable late-1980s autofocus SLRs when judging price.
What affects the value of a Pentax SFX?
Working electronics, a clean LCD, a functioning built-in flash, and the inclusion of a KAF-mount lens are the main factors that lift the price a Pentax SFX sells for.
