My old Pentax glass now works on my Sony E-mount. I've 3 favourite lenses that I've put to the test on it - infinity focus is always exactly where the lens says its going to be. As another review has noted, the release button is not the most intuitive part and even though I'd read his advice, I still panicked the first time when I attached a lens and thought it was stuck there forever. Once you've got the feel for it, it's a breeze and hurriedly switching lenses is no problem. It is comforting to feel that the adapter isn't suddenly going to let go of my lens. The camera side attachment is equally sturdy. It has been on and off the camera frequently and is never any trouble. ## Frequently Bought Together - Fotodiox Lens Mount Adapter - Pentax K AF Mount (PKAF) DSLR Lens to Sony Alpha E-Mount Mirrorless Camera Body with Built-in Aperture Control Dial - Fotasy T Mount Lens to E Mount Adapter, T2 E Mount Adapter, Telescope Lens Emount Adapter, Compatible with Sony a7 a7R a7s II III IV a9 a7c Alpha 1 a6600 a6500 a6400 a6300 a6100 a6000 a5100 ZV-E10 - PCTC Screen Protector fit for Sony alpha 1 a7II A7III a7SII a7SIII a7RII a7RIII a7RIV RX100VII RX100VI RX100V RX100IV RX100M2 A9II,ZV-E10 RX10IV ZV-1 ZV-1M2,3 Packs Tempered Glass Screen Protector --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.us/products/50636038-fotodiox-lens-mount-adapter-with-aperture-control-pentax-k-lens](https://www.desertcart.us/products/50636038-fotodiox-lens-mount-adapter-with-aperture-control-pentax-k-lens) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-07-25*
