Kenko Auto Extension Tube set for Canon EOS allows for use of 12, 20 and 36mm either by themselves or in any stacked configuration.

Works with AF and IS (image stabilized) lenses, but manual focus with IS off is always an option. I used these with a 100mm Macro L IS lens and they worked great.

Mounts are great, small marks on the body - works fine. I've gone to Nikon, so I'd also trade for the same set in Nikon.

Comes with box / instructions

Note: these are for the extension tubes only, they used with a lens - no lens included.

Straight trade for same in Nikon mount

Would also consider partial trade for
Voigtlander 75mm f/2.5 with M adapter would be a bonus
Voigtlander 35mm f/1.4
Voigtlander 40mm f/1.4
