Hi John,

I complety understand what your saying about the fresnel, higher magnification with a fresnel can really bring out some things that make focusing very difficult, the concentric lines of the fresnel under high magnification have a very strong tendancy to interfere with actually seeing what your focusing on., before I perfected the process we are currently using, I had actually stopped using my fresnels in favor of seeing the whole image under higher magnification.

I am sorry, I did not mean to sound smug or anything, was just trying to understand what you were saying, I actually enjoy using my 8x Rodenstock now and love using my 10x at times because of the detail I can see.

Thanks for the clarification.

Good shooting
