Anyone know where I can buy Durst Vegatub lens board for Durst

My understanding is that in theory the lens size should equal the square root of the sum of the squares of 6 and 7. This gives a 90mm lens for 6x7 but a 6x7 neg's picture area isn't quite 6x7 so a 80mm might work but it might be touch and go. If you have a 80mm but not a 90 then give it a try and see if there is an issue. If you are having to buy a lens then definitely go for a 90mm

if you provide the make and model you might a definitive answer. Not all lenses of same focal length have same coverage. Some do a bit more and some less and some are specifically designed as wide angle.

Michael, I have a Durst 670 and use an 80mm enlarger lens for 6x7 negs. It just works fine

FYI Not all 80s will cover 6x7

I use a Schneider Componon-S 100mm f/5.6 for 6x7 negatives, which should cover up to 6x9.
