I don't have that problem with my Perkeo II either. It's not really that the front standard is particularly loose on this model, but that in general the design of the front standard on most folding medium format cameras is not the most stable thing in the world. It's a bigger issue with 6x9 folder, because the bellows is longer and the lens is bigger, so there's more to support and a small movement in depressing the shutter becomes magnified by the time it reaches the lens.
