This is a VILTROX mount adapter with electronic contacts. It allows you to use Canon EF mount lenses on Leica L mount cameras. I purchased it new in September of this year and have been using it with a ZEISS lens (other items for sale). ・Condition The exterior is very clean with few scratches from use. ・Operation I have confirmed that it recognizes and works without problems, including aperture values and lens focal length. I have not tested AF lenses as I do not own any. The included accessories are all shown in the photos. ・Genuine front and rear lens caps ・Original box ・Warranty card I will generally lower the price at my own discretion. I will consider reasonable price negotiations, but please refrain from negotiating prices in the comments. I will prioritize the person who purchases the item, even during comment exchanges (in accordance with Mercari's rules).
