Lens Mount Adapter for Fujifilm X, Pentax K Lens to Fujifilm X

Urth Pentax K to Fujifilm X Lens Mount Adapter — Unlock a Surprisingly Deep Lens Catalog

The gist: An affordable adapter that connects the wide Pentax K lens ecosystem — spanning 50-plus years of production — to compact Fujifilm X bodies, giving budget-minded travel shooters access to underpriced optics.

• Vast, affordable lens pool: Pentax K mount lenses span from 1975 to the present, and older SMC Takumar glass is frequently available secondhand at low cost with excellent optical character.
• Hardened magnalium build: The alloy body is more resistant to warping and corrosion than standard aluminum — durable for multi-destination trips in varying climates.
• Anti-reflection matte interior: Eliminates stray light that can wash out contrast when shooting bright coastal or snowy outdoor scenes.
• Precision fit at a low price: At under $20, Urth delivers the same tight machined tolerances found on its higher-priced adapters — good value for cost-conscious travelers.

B&H Photo carries the Urth Pentax K to Fujifilm X adapter alongside the brand’s full range, confirming compatibility with the broad Pentax K mount family.

Best for: Budget-conscious travel photographers interested in exploring the deep Pentax K vintage glass market on a compact Fujifilm X mirrorless. Skip it if: you need autofocus — all focus and aperture control is manual, and Pentax K-mount AF is not activated through this adapter. Runs ~$19 — check the current price before buying.
