I purchased this new on Amazon on August 31st (see the 5th photo), but I'm selling it because I haven't had much opportunity to use it. A Japanese instruction manual is included. I used it only once with a Sony α7c ii. At that time, I confirmed the eye AF and other operations. ■ This is the latest TECHART LM-EA9 MarkII version with system version Ver.1.8.0.
