sb29s ring flash
wondering if anyone has had experience with the sb29 s ring flash? Do you find it useful for macro work with insects etc? I have an SB 800 flash with off shoe extension cord but it is somewhat ackward to use in situations where I am hand holding. I also use the Nikkor 105 f2.8 macro but feel that using it with a ring flash would allow me a bit more shutter speed especially with butterflies to help with motion blur and possibly my inabilitiy to hold the camera perfectly steady.
Would appreciate opinions from those that use this flash.
