1. Solution for Aperture-less Lenses

This AF-NEX adapter is a key accessory for activating Minolta AF and early Sony A-mount lens inventory. Since these lenses lack a physical aperture ring, ordinary adapters cannot adjust the amount of light entering the lens. As a professional lens manufacturer supplier, we designed a unique “0-7” manual aperture control ring on the adapter body. Through an internal high-precision mechanical lever, it directly drives the aperture linkage at the rear of the lens. This design makes this adapter with a manual aperture dial one of the few solutions on the market that allows depth-of-field control with older lenses on mirrorless cameras, greatly enhancing the product’s practicality and market demand.

2. Durable Copper-Core Construction

For frequent disassembly and reassembly scenarios, we adopted a composite material process with a copper-core aluminum body. The mount interface is made of high-purity chrome-plated brass, utilizing its self-lubricating and wear-resistant properties to protect the valuable Minolta AF lens mount from wear. The lens body is made of aerospace-grade aluminum alloy, precision-cut by CNC and finished with black anodizing. This manufacturing standard, comparable to that of a Sony A-mount lens converter factory, ensures that the adapter ring maintains a tight lock even after long-term use, preventing optical axis misalignment or light leakage, providing a quality guarantee for B2B customers to purchase with confidence.

3. Revitalizing the Vast Legacy Lens Inventory

The Minolta AF system boasts a large inventory of used lenses, many of which possess excellent optical quality (such as the renowned “G” series lenses). This adapter ring provides a low-cost Minolta AF to Sony E mount adapter bulk solution, helping camera equipment distributors and used camera stores seamlessly adapt these older lenses to popular Sony E-Mount (NEX/Alpha) mirrorless cameras. It supports Infinity Focus Allowed, and although it doesn’t support autofocus, it works well with Sony cameras’ “focus peaking” function, delivering an excellent retro shooting experience and maintaining stable sales in the long tail market.

4. Flexible OEM & Stock Availability

As a market-proven, mature, and universally compatible product (Private Mold: No), we can offer highly competitive pricing and extremely short lead times. We support OEM camera accessory services, allowing you to laser-engrave your logo on the side of the adapter ring to help you build brand recognition. Our Guangdong factory maintains ample raw material inventory and supports mixed orders. Whether you need to replenish single items or purchase a full range of adapters, we can provide efficient supply chain support to help you respond quickly to market fluctuations.
