I bought macro extensions from Hong Kong and as you can see, they work just fine. I had to wait about 14 days and it cost me about 6€. Yes you read it right, well it was actually only 5.70€. They don’t have connectors for Auto focus, and I can’t change f value on the newest lenses. But that really doesn’t bother me, because I am using old manual Carl zeis 50mm f 2,8 lens.
