Sony E-Mount Mirrorless Cameras Body - Popular models include Sony Alpha α7 I / II / III, α7R I / II / III / IV, α7S I / II / III, α9 I / II, α1 Sony Alpha α3000, α3500, α5000, α5100, α6000, m α6100, α6300, α6400, α6500, α6600 Sony Alpha NEX-3, NEX-C3, NEX-F3, NEX-3N, NEX-5, NEX-5N, NEX-5R, NEX-5T, NEX-6, NEX-7 Sony Smartshot QX1, QX10, QX30, QX100 Sony Security SNC-VB770, UMC-S3C Sony Handicam NEX-VG10, NEX-VG20, NEX-VG30, NEX-VG900 Sony NXCAM NEX-EA50, NEX-FS100, NEX-FS700, NEX-FS700R Sony XDCAM FS5, FS5 II, FS7, FS7 II, FX3, FX6, FX9 Sony CineAlta VENICE Note If you use an APS-C dedicated lens with a full-frame (35mm) camera, vignetting may occur. Therefore, check whether the lens is an APS-C-only lens or not. The fit (hard, loose, slight play, etc.) may differ depending on the lens manufacturer. Application Manual adapter without electronic contacts, doesn't support autofocus/auto diaphragm/aperture control. Adapting APS-frame lens to full-frame camera, it may generate vignetting, some cameras could correct it by adjust APSC. Adapting full-frame lens to APS-frame camera provides excellent edge-to-edge sharpness. The smaller image field helps minimize the effects of lens distortion and aberration by using the 'sweet spot' or center of the larger lens image circle. And it will magnify the focal length by 1.6 on Canon, 1.5 on Nikon and Sony, 2.0 on M4/3 camera. Set camera "release shutter without lens" to enable when using the adapter for the first time, or the camera will fail to recognize the lens and the shutter may not be released. Why Should You Choose K&F Concept？ Professional camera accessory manufacturer. Reliable partner in your photography life. Premium picked up products. Adapters are made of metal sealing ring, much tighter, with laser fonts, much durable. Suitable for Lens: M42 Screw Mount SLR Lens Camera: Sony Alpha E-mount Cameras (NOT for Sony A mount cameras) Properly installed when you rotate about 90 degrees and hear a light "click". Please screw the lens adapter lightly and skillfully, needn't too much force. Infinity focus position The position of the infinity mark [∞] of the telephoto lens or super telephoto lens is shifted slightly to the positive side to enable focus adjustment even when focus shift is caused due to temperature changes. The shift range is denoted by an L-shaped line, Be sure to check the focus through the viewfinder even when you shoot at infinity. Note: 'No Lens Attached' - Warning Message Appears The camera needs to be set to function without an E-Mount lens attached. You can do this by changing the following camera setting: 'Menu' -> 'Setup' -> 'Release w/o Lens' -> 'Enable' (Exact naming and location of this option may change depending on camera model). If your lens does not have a manual aperture control ring, it will stop down to its smallest f/stop by default. Review: Works perfectly for Vintage Lenses - Perfect for vintage manual m42 lenses on my Sony a5100, build quality is all metal so it is durable and can hold the absolute tanks that are old Russian lenses. Especially when the lens weighs 3x the weight of the body :') Review: Exception quality - The quality of these adapters are unreal. This will be my second m42 adapter from K&F and both are exceptional quality, and accommodate the small aperture pin on these lenses. My only feedback would be ideally if the adapters were a bit lighter, especially as m42 lenses themself tend to be on the heavier side so the weight does become a little much but not enough for me to not use them by any means. ## Features - 【Features】 Manual adapter without electrical contacts, supports focus to infinity.

Especially when the lens weighs 3x the weight of the body :') ### ⭐⭐⭐⭐⭐ Exception quality *by F***Y on 3 March 2025* The quality of these adapters are unreal. This will be my second m42 adapter from K&F and both are exceptional quality, and accommodate the small aperture pin on these lenses. My only feedback would be ideally if the adapters were a bit lighter, especially as m42 lenses themself tend to be on the heavier side so the weight does become a little much but not enough for me to not use them by any means. ### ⭐⭐⭐⭐ 90% perfection *by F***E on 8 May 2020* Really well made and so very fine as a design item. Works really well. Fits really well. The only weakness is the glossy internal black finish that reflects some light sometimes and creates glare in some images. Paint your barrel internal shaft matt black K&F! C'mon! I spray painted the internals after taking it apart. It only takes 30 minutes. Taking into account a top quality adapter tears your money for over £100 this is a very good adapter if you are able to paint the insides. And it is incredibly heavy, but it feels superb. ## Frequently Bought Together - K&F Concept Lens Mount Adapter Compatible with M42 Lens to NEX E-Mount Camera Compatible with Sony Alpha NEX-7 NEX-6 NEX-5N NEX-5 NEX-C3 NEX-3 - Unbekannt Zenit Helios-44-2 Helios 44-2 58mm 58 mm 1:2 - M42 M 42 --- ## 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.jp/products/47955735-m42-to-nex-lens-mount-adapter-for-m42-screw-mount](https://www.desertcart.jp/products/47955735-m42-to-nex-lens-mount-adapter-for-m42-screw-mount) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-08-08*
