has the Vello Ringbox
available for $59.95 with free expedited shipping. Regularly $89.95.
The Vello Ringbox seems to be a clone of the Roundflash Ringflash Adapter
which retails for $113.00. I purchased the RoundFlash around Christmas of last year and have enjoyed playing around with it. It makes an especially useful tool for macro subjects.
In fact, I just walked out onto my front porch to capture this image of a Rosemary bush using the Canon EOS 5D Mark III, EF 100mm f/2.8 Macro USM, 580EX Speedlite and the RoundFlash Ringflash Adapter.
EXIF: f/7.1, 1/100 sec, ISO 100 (exposure reduced by 1/2 stop in DPP)
The exposure settings meant that the shaded fence behind the plant fell into darkness making this outdoor shot look like it was captured in a studio. The soft, even light of the RoundFlash allowed for every detail in the subject to be visible. [Sean]
