...and just when I was about to splurge on a Canham. Which, actually, I still might do. But anyway...

Now that I have an up and running B&J 5x7, I am wondering about a fresnel for it. Every time I have obtained a fresnel for an LF camera, there happened to be one made specifically for it or it came installed.

Is this the kind of thing that is easy to do myself? Is it the kind of thing I can just cut down from a larger one and tape to the inside of the GG or something? I am worried about plane of focus first, then fit, then pretty (since it's a pretty beat up B&J anyway).

Thanks for whatever you can offer.
