Does anyone here use an 80mm lens (mine is a Super Symmar XL if that matters) on a Technika 4x5 camera (IV, V, or Classic Master)? If so, have you found it necessary to use a recessed lens board? I've been playing around with my lens on a Classic Master and it seems like it will work fine with a flat board and the top rail pushed all the way to the back of the camera. However, I remember Bob Salomon saying here that a recessed board should always be used with a 90mm or shorter lens on Technikas. I used a flat board with a 90mm lens on my former Technika V and it worked fine but I thought maybe the advice was valid with an 80mm lens. If you use a recessed board, do you also have to use the special angled cable release and if so, where do you get them and what do they cost?

My normal practice is to spend the money first and ask questions later but I just looked at the cost of recessed lens boards, even the generic ones much less the Linhof ones, and thought asking first might be advisable in this instance.
