"Zoom setting for SB-25 and Sto-fen Omnibounce?"


San Francisco, US
          

I just picked up a Sto-fen Omnibounce for my SB-25. With my SB-80DX, it automatically sets the zoom setting to 14mm with the diffuser on. Should I do something similar on the SB-25? The lowest zoom is 24mm. Or should I let it zoom according to the lens?

Thanks!

Dear Jason,

It's not necessary to set the zoom head to the widest setting with the Omni-bounce, but it may help with even illumination if you use it forward-facing (i.e., in direct flash as opposed to bounce). Many photographers use it bounced off a ceiling or wall, and in that role it doesn't especially matter.

The SB-80DX sets the 14mm head position because the purpose of that diffuser is to provide wide angle flash coverage, while the primary purpose of the Omni-bounce is to modify (soften) the quality of light from the flash. In practice, the difference is minimal to none, and either can be used for either purpose.

Thanks Stuart for the response. That seems to make sense.

As for the SB-80, perhaps I used the wrong word, I meant the sto-fen equivalent soft-box thingie for the SB-80 sets it to 14mm. Would you happen to know why it does this?

Thanks,

The Nikon-equivalent diffusion dome activates a switch to set the zoom head to it's widest setting, since that accessory is intended to allow the use of flash with wide angle lenses down to 14mm. It's mainly to insure that the flash range display is reasonably accurate.
