Funny you should ask about lenses. I've just had two ULF lenses on Ebay, both rare and in near perfect condition-- and no bids. One was a Dallmeyer wide angle Rectilinear No. 4, which covers 20x24. The other was a Dallmeyer Long Focus Rapid Landscape Lens, also covering 20x24. I was asking $1200.00 for the wide angle and #1500.00 for the Landscape lens, which was offered with its original box, lens caps, flange, and original yellow filter. No bids on either lens, which I find surprising. Why??
