The 150mm lens should work fine, but remember that the front standard, where the lenses attach, can physically go only so close to the negative. Lenses shorter than approximately 100mm on a Vapla board will not get close enough to the negative to focus. The solution is a recessed lensboard, Laratub, that has a 39mm Leica thread for the smaller lenses and is recessed about 2 inches.
