Years back I came across some 4.5" Tiffen filters on closeout for what was probably an obscenely low price and purchased a retaining ring that would hold them. They have no threads. It was tricky to find these as I wanted to use them with the early Blad 40mm with the monster front element. After all that trouble I never used them though! Got an orange and a green 4.5" I'll be happy to sell! ;) e ________________________________ From: Bob Younger <ryounger@xxxxxxxxx> To: pure-silver@xxxxxxxxxxxxx Sent: Monday, February 20, 2012 7:03 PM Subject: [pure-silver] Re: B+W Out of business??? I wish I could get away with 82mm; I do use step-down rings for my smaller lenses. But for most of my lenses I need the 95mm; and for some I need the 105. For my even larger lenses (210 SA)I have moved the filter to the rear element. The joys (and expenses) of LF photography.......
