Re: [photo-3d] Re: Tri-Delta Prism Adaptor

[Peter Davis <pd@xxxxxxxxxxxxx>]

Is the adapter essentially a step-down ring?  Does it have any optics in 
it?  Basically, I guess I need 52mm to Series 5.  Still, as I said, I would 
think a simple step-down ring would cause severe vignetting, since so much 
of the lens surface would be blocked.

Thanks,
