Chip,
Unless the Tamron extension tube is like the Vivitar Series 1 90 2.5 macro
(Tokina) and has an element in it, there would be no advantage to either
style of tube. If no optics exist, there would be no optical advantage

Subject: [OM] Ext tube for Tamron 90mm/2.5 SP
Is there a specific advantage to using the Tamron extension tube with their
90mm/2.5 SP instead of say an Olympus auto tube?
Thanks
