Commlite 0.71x AF Adapter AEF-MFT Booster This adapter is for using EF lenses with Micro Four Thirds cameras. I purchased it used in August 2025 with the intention of using it with a BMPCC4K, but I only tested it and hardly used it. The caps are CANON brand. There is no tripod mount. It is relatively clean, but it is a used item, so please understand this and only purchase if you can judge from the photos.
