Minolta Extension Tube for Minolta SR lens mount_Topcon all metal & Bakelite constructionThis is a modular extension tube set for Minolta MD mount cameras, with a maximum extension of about 67mm, and a minimum extension of about 7mm. It's adjustable by adding or removing threaded rings (or, in the case of the shortest extension, ignoring the rings entirely.) Worth noting that there's no autodiaphragm function on this tube: you'll have to stop down manually. In excellent condition, with box.
