I have an Intrepid fresnel on my Intrepid 8x10 v2 camera. It's okay, but not great; haven't seen different fresnel screens, but this one seems to have a rather course cut which means the lines are easily seen when viewing the ground glass. What I really don't like about it, is that your angle of viewing has to be in a certain position or the screen goes nearly black. When making camera adjustments like tilt for near/far focus, I like to watch both the near and far image areas as I refocus. This is difficult with the fresnel. I also like to check my corners which is, also, made more difficult with the fresnel. These issues may not bother you, of course.
