Dave, I think I am right in saying these only work with a camera that has had the conversion is that right? (Digital SLR I mean). If so then I'll leave it but what did you use for the shots you showed? I assume they were with a film camera. I haven't got one of those anymore, got rid as I wasn't using it.
Anyway, if you think it might work on a dSLR then I'll have a pop, if not then I won't
Cheers,
Rob
