I have the D80 and a Nikon DX lens (18-200). As already partly described by other customers, the intermediate rings are not suitable for me, because my lens does not allow manual iris adjustment. The picture remains dark even with the brightest lights. Unfortunately an inquiry with Khalia.de yielded no solution. My first incorrect assumption, a stronger light lens could solve the problem was even falsely confirmed by Khalia.de.
Conclusion:
In this respect I find it more than inappropriate to offer the product for a D80, without referring to this serious situation. I am disappointed by the expertise of the employees and the offer description of Khalia.de.
