Opinions?

I also think that this would be a cool set-up. It could essentially duo as a make-shift portrait ring-flash. The biggest problem I see is that it only "Attaches directly to EF 50mm f/2.5 Compact Macro, EF 100mm f/2.8 Macro (both versions), and MP-E 65mm Macrophoto Lenses (can also be used with EF 180mm f/3.5L Macro USM via Macrolite Adapter 72C)". There's an adapter to mount it to the EF 180mm f/3.5L but that lenshas 72mm threads. The only lenses I'd be interested in mounting this to (when not actually doing macro photography) would have 77mm threads. On top of that its guide number (unlike the 430EX &amp; 580EX) is measured in feet instead of meters. Unless you can shoot at f/2.8 you better be VERY close to your subject. I guess if it's more for fill or those cool circular catch lights you may get a little more wiggle room there but I would concerned with power. I may be wrong though since I am only beginning to understandflash photography[]


On a side note theExpoimaging Ray Flash Adapter for Canon 580EX states that "The Ray Flash results in minimal light loss from your flash's standard output". Can anyone verify this (Keith B)? Also, has anyone used this as a macro ring-light?
