DIY Iris Repair of the Maxxum 70-210 f/4 Beercan

An advanced repair project.
This repair requires complete disassembly of the complex floating element zoom body.
Grease from the floating element mechanism can contaminate the iris blades, causing innacurate exposure.

Disassemble the lens down to the floating element body as shown in the master gallery.
Improvised tools help with reassembly.
