This is a RAYQUAL mount adapter. (It's a conversion adapter.) Compatible cameras: Sony αE (compatible with α7, α5000, and α6000 series) Compatible lenses: Contax Yashica Condition: I used this for about two years after purchasing it new, so there are some scratches, but I think it's in relatively good condition. Please check the photos and make your judgment. *No box, caps, or instruction manual. Specifications (from the sales site): ・Compatible cameras: Sony αE (compatible with α7, α5000, and α6000 series) 　Compatible lenses: Contax Yashica ・How to use: Set the camera settings to manual or aperture priority AE. ・Focus using the lens's focus ring and aperture ring. 　Use the widest aperture to focus, as it uses stopped-down metering. ・Electronic contacts are not used, so the autofocus function is not available. ・Good usability with anti-reflective processing on the inside and Teflon processing on the surface. ・Made with 1/100mm precision in a plated state. ・An anti-reflective cover is also attached inside the camera to cover internal reflections. ・On α7II and α7RII, you can manually adjust the focus even through the adapter. ・When attaching our adapter to the α7S, α7II, and α7RII bodies, it may feel tight, but there is no problem. Shipping: It will be packed with air-cushion packaging and shipped in a cardboard box. Please consider and purchase after understanding the above. #RAYQUAL #MountAdapter #ConversionAdapter #CY-SαE #Contax #CONTAX #Yashica #Sony #sony
