There's a ton of lenses that will do fine, even a 50mm f/1.4, but even on Canon, I'd use the Nikon 85mm PC (the first one, not the latest one that was just released recently). You get to have perspective control, and it close-focuses down to 1:2, which is an advantage over the Canon 90mm tilt/shift.
However, I think the choice of lens is secondary to lighting and the overall setup. Lighting is key. Your lens selection is obviously tied to your composition. Composing, focusing, and locking down the camera and also not moving the objects, is an important step before you set up your lighting, because movement/position of the camera and the focal length of the lens is directly related to how highlights and light sources will act upon the subjects, depending on the types of surface properties they may or may not have (glass, metal, reflective, non-reflective, etc).
But yeah, I think the 85 PC is a good lens to have.
