I got an Olympus extension tube for mine after I got the lens. I find the
adapter is a pain in the a-- to remove and reattach which you would have to
do each time you need to add a little extension to the Tamron lens. With
the Oly tube you just attach it to the body like a lens and then attach the
90 with adaptor with a quick bayonet motion.
