Manfrotto 190XPRO3 lens mount_Mamiya 7 but it's still no joke:The 190XPRO3 is an updated version of the classic all metal compact tripod from Manfrotto, with easy to use flip locks. This XPRO3 version features a centre column that can be flipped horizontally (for close up or copystand use) without removing it from the tripod. Extends to about 5 feet without centre column. Accepts any head with a standard 3 8" thread. Light cosmetic wear, good function.
