Hi,
I have this 90mm Goerz Dagor, and it seems like i cant really get this lens focused on my Canham 5x7 camera. Is this lens not supposed to work with 5x7? or, is there some techiques that i am missing?(i am very new to large format)

Also, for a starter, what kind of wide angle lens do you guys recommend? I can't afford any expensive lense, and I just have a budget of $500. I will be shooting mostly black and white.

thanks

sean
