Alternative without micro positioning is 357 UNIVERSAL SLIDING PLATE link http://www.manfrotto.com/Jahia/site/...id=107&idx=115

The 357 is cheaper but not as effective as the 454 particularly at these magnifications.

Anyone with a set of bellows may be able to adapt them as a focussing rail.

I have a set of Olympus OM bellows which haven't seen much use in recent years but by adding the 'Focus Stage' and removing the actual bellows bit you have a first class unit to fit many cameras.

Finding a focus stage for sale is the hard bit - I eventually homed-in on one (new!) at B&H in New York at a very reasonable price. B&H seem to have a bit of a 'mixed' rating from customers but I ordered my unit on a Thursday morning and it arrived the following Tuesday morning. This was a few weeks ago when the exchange rate was about $2 to the £ and the total cost including quite a lump for postage was £44
