I currently use Nikon F6 and D40 with 17-35 AFS, 70-200VR AFS, 55mm AIS for studio work with Hensel Integra Pro, which mostly includes portraiture, modeling and still life.

I never used medium format. Will I benefit if I add Contax 645 with three lenses Planar T* 80mm F2.0, Distagon 2.8/45 and Sonar 2.8/140 ?
Will Nikon D3 be a better buy ?

Thanks
