Yeah, I wasnt thinking, I wouldnt be so sure the distance added by the step up would be problematic. The only experimentations Ive done with coupling vs just reversing with an adapter/reversing with tubes/adapter, I used step ups. I often use a Raynox, which I know isnt quite the same, but when I use my front mounted twin flash it pushes it out more than just a few mm and I havent noticed any difference. Id be more concerned about it increasing vignette than anything probably.

My understanding is that a lens that is reversed on to a normally mounted camera lens acts as a close-up lens. And as far as the distance between a close-up lens and the camera lens goes I have used a configuration with a close-up lens (Raynox 150/250) mounted on the end of a fixed tube, within which the camera lens extends and contracts (this is with a fixed lens bridge camera). The distance between the camera lens and the close-up lens varied from not much to two inches or so. I wasn't aware of any problem.
