Hi Daniel,
Thanks for the reply, these resources are great. In terms of the optical qualities I'm after, I'm looking for the type of qualities that something like a Superspeed might give in terms of flare and softness. There seem to be some great new lenses coming out now that offer these characteristics, so I don't necessarily need one that was manufactured decades ago. However, just out of interest, I'd love to know what lenses were manufactured prior to digital large format cameras that would cover a full frame.
Cheers,
