支持EXIF信息 SHOTEN推出徕卡M转佳能RF卡口转接环

Core Viewpoint - SHOTEN has launched a new LM-CR ME adapter ring that allows Leica M mount lenses to be used on Canon RF mount bodies, priced at approximately $249 and weighing about 97 grams [1]. Group 1 - The LM-CR ME adapter ring features electronic contacts that support EXIF data recording and provide camera-assisted focus indication, but it does not offer autofocus capabilities like some other adapters [3]. - The adapter includes a 4mm helical structure that reduces the minimum focusing distance, giving it some macro capabilities [3]. Group 2 - The Leica M mount inherently has only 6-bit lens recognition without electronic contacts, necessitating a connection to a computer to register lens information, including lens name, focal length, and maximum aperture, with a capacity to save information for up to 10 lenses, making it somewhat complex to use [5].
