Dear Bobwysiwyg, if you like to do it right way, just follow my instructions as it shown above. I have a ShenHao and I used to install Fresnel on this camera few times. If you have a Fresnel directly made for the Shen Hao you will be ok. The kind of problems as Dan Fromm mention above may happens if the camera not disigned for the Fresnel at all, ore if the fickness of the Fresnel lens are bigger than required for that particular camera. But as i said above, Shen Hao has a spot for the fresnel and camera designed for the fresnel, they just sell it separatelly as an option, and if yours Fresnel made directly for the ShenHao the lens will fit in its spot with out affecting the ground glass position. This is the right way to go.
