Da sensacion de calidad, ya que es metálico y se nota su peso. Review: This adapter is very well built and works perfectly with my m42 mount lens. It also accommodates m42 lenses with the pin for aperture control. The connection to the camera mounts perfectly with no play. The only problem I can note is that the adapter itself is a bit heavy. Otherwise this is a great affordable manual adapter for m42 lenses. ## Features - Smooth surface for effortless mount,infinity focus allowed. - Made of brass and aluminum (not plastic), anodized aluminum construction. - Please note: This adapter is NOT compatible with Sony A7II, A7S. - Compatible Cameras (Including, but not limited to): Compatible with Sony NEX-3 NEX-3C NEX-3N NEX-5 NEX-5C NEX-5N NEX-5R NEX5T NEX6 NEX7 NEX-F3 a6000 a5000 a3500 a3000 Alpha A7 A7R NEX-VG10 VG20 etc NOTE: This adapter will NOT fit on the Sony a7S, a7 II, a7S II, and a7R II. - Please note: 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. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00LECY8OW | | Best Sellers Rank | #160,629 in Electronics ( See Top 100 in Electronics ) #20 in Lens Flash Adapters & Converters | | Country of Origin | China | | Generic Name | mount | | Importer | Shenzhen Zhuoer Photograph | | Included Components | Mount | | Item Dimensions LxWxH | 6 x 12 x 12 Centimeters | | Item Weight | 40 g | | Item model number | KF06.067 | | Manufacturer | Shenzhen Zhuoer Photograph, Shenzhen Zhuoer Photograph | | Net Quantity | 1 Set | | Packer | Shenzhen Zhuoer Photograph | | Product Dimensions | 6 x 12 x 12 cm; 40 g | ## Images ![m42 to e Mount, K&F Concept Lens Mount Adapter M42 Lens to Sony NEX E-Mount Camera for Sony Alpha NEX-7 NEX-6 NEX-5N NEX-5 NEX-C3 NEX-3 - Image 1](https://m.media-amazon.com/images/I/61+6vbPPe6L.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by A***. on 13 January 2021* Lo uso con un Helios 44-M4 y se adapta a la perfección, no tiene holguras y el acabado es excelente.
