Possible to loan me one to test it out before i consider buying one? With an extra element in the light path i still can believe it'll brighten up the image :D

just imagine a magnifying glass doing the sunray exeriment. it concentrates the light source from a wider field to a narrower field, so the light is now more concentrated therefore 'brighter'

try this link http://www.isomedia.com/homes/cvedeler/ ... ducers.htm
it explains how it works and why is it brighter.

Thats a very informative link. But it talks about improvement with regards to imaging, what about visual performance?

Oops now then I post because the shipping took quite a long time.

Hommel: Visually, its essentially a smaller and brighter view with rather bad abberations at the edges. Ok, I can lend you a SCT reducer to try out.
