I have no experience with your camera, but I use extension tubes with telephoto lenses to photograph bees. I posted this:

Telephoto Lenses for Bee Photography

I have found that an extension tube of about 10% of the focal length of the lens allows autofocus.  Longer tubes tend to reduce ability to autofocus.

I have also found that a tube of this length will approximately double the maximum magnification of the lens.  For example from 0.18 without a tube to 0.36 when using the tube.

I crop heavily, saving about 15% out of the center of the image.  That leaves a decent number of pixels for posting online or emailing.  And it's also quite ok for printing.

Best,

Alan
