Kenro Tubes

[JJM]

I would be grateful for anyones thoughts on Kenko tubes to use with my EF-100mm macro lens?

What additional level of focal lenth would they make the lens?

Also I remember a few weeks ago seeing some pics of a coin shot a lots of different focal lenths, I am sure some of the images used the tubes but I can't remember where it was posted, does anyone remember seeing this or where it was?

Cheers,

Jon

You'll get about 2:1, loose infinity focus tho.
