Hello,
I finally found the correct Linhof recessed lensboard for my 75mm Biogon, not an easy task! The lens board has the quick release, thus the lens is positioned a ccordingly (there are four screws on the mounting flange so the lens can only mo unt in four positions). I have several ebay pictures along with Linhof catalogs and "Large Format Photography" for references. I know the Lens is mounted in t he correct position.
OK here's my problem: The aperture ring has a knob on the lower half of the len s for easy adjusting. As the ring is turned clockwise (widens the aperture), th e knob hits the base of the front standard and won't allow the aperture to open fully (I think it stops at around f/8). If I raise the front standard it will c lear. According to the instruction book, the bed does not have to be lowered an d of course, the front standard should be in "zero position" for swings/tilts/sh ift/rise. What's going on? Does anyone have a Biogon mounted on a resessed boa rd with quick release??? If so, could you please check this out. Thanks for you r help!
One more interesting note: I bought a 95mm Heliopan rubber lens shade and it fit s on the lens mounted on the camera...it JUST clears it! Of course I will have t o use it collapsed due to the extreme wide angle, but any shading is better than none! Quite a sight!!! It looks like a piranha ready to attack!
