Should I get one for my sony a6000? I already have a Sony SAL18-250 mm lens before I bought the Sony a6000. But when I bought the Sony a6000 I also bought a Sony E 18-200 mm lens specifically built for the Sony a6000. Should I return the Sony E 18-200 mm lens and just get the Sony A mount to E mount adapter to use my Sony SAL 18-250 mm lens with the Sony a6000? What are the pros and cons of the adapter and using an A lens for an E camera? I really don't mind keeping the E lens anyway. Please advise. Any help or suggestions will be greatly appreciated. Thanks.
