Andrew Reid from EosHD (Click here) discovered that the very acclaimed EOS to E-mount adapter with electronic controls from Metabones was defective! Andrew says the optical design has “major ghosting and inner reflections from the internal plastic housing.”
The good news is that Metabones now fixed the problem with an anti-reflective part. If you already own one of the first issued adapters contact Metabones and send your adapter back for a service!
