I purchased this along with an EOS M200, but I'm selling it because I haven't had a chance to use the adapter. ① Used once, but in near-new, excellent condition. No outer box, case, or instruction manual. ② Includes front and rear caps. ③ Front mount: Canon EF mount (for attaching EF lenses) ④ Rear mount: Canon EF-M mount (for attaching to EOS M cameras) ⑤ Compatible lenses: EF lens series ⑥ Maximum diameter: Approximately φ66.6mm ⑦ Length: Approximately 26mm (body only) ⑧ Weight: Approximately 110g (body only) #MountAdapter #EOS #M200 #EF-M #Canon
