Generic extension tube set for Canon EF

Description

This is a very simple extension tube set for Canon EF mount. No electronic coupling, no nothing, just a mount on either end and some tubes in the middle. This means you don’t have aperture control on EF lenses, so you’ll need to set your lens aperture on-camera before removing the lens and attaching it to this tube: not the most convenient thing in the world, but there you go.
