Well, the Oly WA diffuser is an abbreviated cross-section of a Fresnel
lens, so I assume that it distributes the light dump a little better than
a homemade one would. Also it's transparent, so there's probably a
little less light-loss. IMHO. Of course.
Odd, the pics on the eSIF have it looking "milky" translucent. anyway,
searching about, i figure i'm best off with a Pocket Bouncer by Lumiquest.
Yep . . . the WA is the "optical white" WA diffuser. IIRC, Garth is
describing the tele adapter. Note that some WA diffusers for *other*
brands of flash units do resemble a Fresnel (notably the one for my Metz).
BTW . . . the Lumiquest is larger and will soften more than the OM WA
panel, and it won't affect the flash sensor if it's installed correctly. I
use the larger version on my Sunpak 544/555 handles (that have larger
heads) and it works fairly well . . . again at closer distances (about
10-12 feet and under).
If you do have a problem with a diffuser spilling light into the flash
sensor, an opaque shield to shade the top of the sensor from the diffuser
will fix the problem.
