Commlite CM-AEF-MFT II This is an electronic mount adapter for connecting EF/EF-S lenses to M4/3 cameras. I am selling the adapter because I have sold almost all of my Canon lenses. Usage frequency was very low. Price negotiations are possible, but please understand that I will not respond to rude messages. Thank you for your understanding. - Brand: Commlite - Model Name: CM-AEF-MFT II - Type: Electronic Mount Adapter - Retail Price: ¥21,600 Thank you for looking.
