Difference between ? Linhof Technika lens boards ?
Like many, I have standardized on Linhof Technika lens boards.
My Canham Traditional front standard takes them, my Technikardan 45s takes them and I have a Sinar to Linhof adapter created by SK Grimes.
All but one of my Linhof boards fit my adapter board, except one which is too thick? What's the deal here, are there two or more types ?
