UPDATE: Metabones inform me they have fixed the latest adapters with an anti-reflective part. If your adapter suffers from reflections, if yours has any of the issues below, simply contact Metabones and send your adapter back for a service As if the initial non-functioning firmware with the NEX 5N and NEX 7 wasn’t bad enough, it appears Metabones will have to completely re-design the recent EOS lens to E-Mount adapter.
