Debunking rumors: No Otus A-mount prototype is around yet :)
PDNonline wrote that they tested the A7/A7r with “the so-new-it’s-still-a-prototype Zeiss Otus 55mm f/1.4 (via the LA-EA3 adapter)“. If true this would mean they had an A-mount Otus Prototype in their hands! But guess what…this isn’t true. They just confused the Metabones EOS adapter with the LA-EA3 adapter :)
