I have a Linhof Tech IV which I like to use outdoors. Unlike the 4x5 monorail I am accustomed to, the Linhof does not have a fresnel screen. Can I simply purc hase a fresnel for it and install it or will the focus cams for my lens then be inaccurate? Or does the fresnel screen need to be installed by someone like Mar flex?

Also -- I have a cam for only 1 of my lenses and would like to add more lenses a nd cams but am on a limited budget. Anyone have a clue how much it costs to hav e a Linhof cam cut?

Thanks for any answers -- I have skimmed through some of the topics under discus sion I feel like this is a goldmine of good info!
