I should have been more succinct.
There are two way to get extra distance for your guide camera to focus.
The cheapest is to insert a small plastic lens between the guide camera and the prism in the camera port. This small lens alters the prism light just slightly so that the guide camera can come to focus. It doesnt affect the main camera at all.
The second manner is to place a 5mm machined aluminium spacer between the front of the camera body and the rest of the camera. This shifts the main camera focus and the guide camera focus by 5mm enabling the guide camera to focus easily.
Hope thats clear.
