Contax: 139Q, 159MM, RTS3 (see below) & Mirror Slip Issues by estimate only depending on camera.
Nikon: F3, FM, FE, FE2, FA, FM2/n & some lenses.
I am unable to repair ANY of the following cameras:
T, T2, T3, G1, G2, TVS, AX, Aria, 645, N1, due to the complete lack of spares worldwide.
A few years ago, Kyocera recalled ALL spares, service data, technical charts and sent them to landfill which means there are simply no spares available or those damaged cameras that could be used for spares are fetching ridiculous prices on auction sites.
