If you were to use the extension tubes with the 20, you would need
different framers that were wider and closer.

The extension tubes can be used with the 28 or 35. The framers for
the 28 are a bit wider and closer than those for the 35. Framers
for the 20 would have to be still wider and closer. And you would
have a heck of time getting front lighting on the subject because
it would be so close to the lens. Lighting is a bit problematic
even with the 28 at 1:1. Upside of the 28 is that it's sharper
because it's optmized for in the water.

There were several manufacturers of tubes. Only one or two made
the framers for the 28. Most only made framers only for the 35.

I suspect that the closeup kit would work on the 20, but cut off
the corners.
