Cambo Wide DS problem

[/dev/null]

Hey,

I'm using a Cambo Wide DS with a 65mm lens and 4x5" revolving back ( http://www.cambo.com/Html/products_photo/set01/english/internet/Item21915.html ).

But for some reason I am unable to focus and all seems unsharp when focussing, am I missing something here? It cannot be used in combination with the 65mm lens? I use a grid glass to focus without any issues on my older Cambo (580 and 750) series.

Thanks.

Solved! I need an extra 'spacer' on the back

Oh hey where do you get the spacers?

I ask because i have a cambo 470 heilical designed for a 47mm XL, but I have a 47mm digitar lens. The XL has a considerably longer back focus than the digitar. The helical wont get infiniti with the digitar even when adjusted.
Oh wait never mind that means I need the lens closer to the focal plane not farther. Sorry answered my own question.
