I got this to attach an old Helios 44 lens to, and it did the job flawlessly. No vignetting, and the build quality is very good. All of that at the low price point. ### ⭐⭐⭐⭐⭐ Well designed adapter *by B***N on January 24, 2026* We'll designed adapter. Works well with my Sony alpha. ### ⭐⭐⭐⭐⭐ Works perfectly for Sony FX3 and Helios 44-3 *by T***N on August 25, 2023* Helios 44 series can be finicky lenses to adapt based on when they were made. My lens is a Helios MC 44-3 from 1987. Cheap adapters do not function correctly with this lens. I bought this one, and didn't even need to make adjustments at all. Locks tight onto the lens, no play or wiggle, and allows me to adjust focus with no issues. Not sure if it actually adds any contrast with the interior coating, but it doesn't as I love the photos that it renders. You pay for what you get, don't buy cheap. ## Frequently Bought Together - K&F Concept Lens Mount Adapter M42-NEX IV Manual Focus Compatible with M42 Lens and Sony E Mount Camera Body - TTArtisan 75mm F1.5 Swirly Bokeh Full Frame Camera Lens Large Aperture Lens Compatible with M42 Mount Camera Lens (Black) - TTArtisan 100mm F2.8 Full Frame Bubble Bokeh Lens Camera Lense Compatible with M42 Mount Camera Lens --- ## 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.co.za/products/431721468-lens-mount-adapter-m42-nex-iv-manual-focus-compatible-m42](https://www.desertcart.co.za/products/431721468-lens-mount-adapter-m42-nex-iv-manual-focus-compatible-m42) --- *Product available on Desertcart South Africa* *Store origin: ZA* *Last updated: 2026-09-29*
