Aputure DEC LensRegain Canon EF to Micro Four Thirds Lens Mount Adapter Featurs 0.75X Magnification Super 35mm View - A Focal Reducer, Lens Adapter, Wireless Follow Focus N Wireless Aperture Control

I bought this item in 2017. It worked as advertised but the built quality started to fall apart. I asked the company to fix or replace it since it was still under warranty. They told me to mail it back to them, which I did. It's now 2021 and I NEVER got a replacement NOR was the item I shipped to them for repair returned to me. So I paid over $400 for an item that started to fall apart and the company took it back with a refund. So I no longer have the item or my money. DO NOT BUY THIS. AND DO NOT BUY FROM THIS COMPANY.

Works well marrying my canon ef 24-70mm usm l lens to my GH4 body. I wish it has the ability to control the shutter speed. I find myself constantly using the handle controller and my camera controls as a result which defeats the purpose of remote control. The glass is fantastic and pictures turn out beautifully sharp and colorful.
