Purchased this just before I sold my Canon R5 and R7 and moved to Sony.  I tested it once using the Tamron 35-150 EF lens.  It worked fine but I decided not to remain with Canon so this item is up for sale. I'm located in Portugal so I prefer to ship within the EU.  I'm willing to negotiate the shipping cost.
