Great piece of kit - but for those purchasing this item it is a dumb lens adapter.meaning there is no electronics on it,as per instruction.I use it om my canon M10 shutter-less camera and the lens fits to the adapter and I can only shoot in manual focus only - this item is a quality product that I personally recommend
Sony A Lenses to Canon EOS M Camera Mount Adapter
Works for Sony Alpha Lenses
Works perfectly with my Sony Alpha lenses on my Canon EOS-M. You have to turn off the auto focus (Google it) to get it to work.
