The purpose-built adapter for the 138 float is necessary because the mounting system is different than copal. I won't believe it doesn't tilt until I see it. The 138 float is all forward weight and will be very demanding on any gearing system.The Pico is very much reinforced at the front. That is also why it has such an odd shape. We discussed it yesterday with the people from A/S. I think it makes a lot of sense as cameras tend to get lighter and bayonet mount lenses can get quite front heavy. Never had a 138 in my hands, but they offer a purpose-built adapter ring for the 138 that they showed yesterday. So I reckon the Pico is capable of fully supoorting that lens.
