Rob and Shaun; The 6000 has a 52mm filter thread so no adapters are required for using the S1 105/2.5 Macro. It came with a stack of adapter rings as well (including 58mm), but none of my macro rigs (the 105 or the 200 w 100 bellows or 50 reversed) requires them so I have no experience with vignetting. I built an adapter using a rear-lens cap and filter ring to allow the ring light to screw into a reversed lens. I used a 52mm filter ring since that is the size of the threads on the flash. No examples of 2x or 4x with the flash. Haven't had the opportunity yet. I'll see what I can do this week or next, now that the bugs are out and about.
