Though it's relatively pricey, you can't go wrong with a 4x5 Sinar P2 or P1. Its rigidity and unlimited bellows draw are ideal for your art reproduction work, while its all-geared movements are highly desirable for small product photography. Sinar uniquely includes features which greatly assist setting tilts, swings, and aperture to get the necessary depth-of-field. In addition, its modularity makes it very versatile -- it can be equipped to shoot 8X10 transparencies if needed. Finally, Sinar Bron is the most committed of the LF manufacturers to digital photography.

An ideal "process" lens for repro work is the Rodenstock Apo-Ronar. The 240mm f/9 will cover 4x5; if you might also need to shoot 8x10, the 480 mm f/11 would be a good choice.

The best type of lens for small product photography depends on scale of reproduction. For subjects requiring scales of 1:4 to 4:1, I'd recommend a Rodenstock Apo-Macro-Sironar (also sold as the Sinar Macro-Sinaron) or Schneider Makro-Symmar 180mm f/5.6. For tiny subjects, a Schneider M-Componon would be better.

If you prefer a single lens for both repro and small product work, consider a premium normal lens such as a Rodenstock Apo-Sironar-S (Sinar Sinaron-SE) 210mm f/5.6. This type of lens permits generous movements for 4x5 and quite acceptable image quality for all but the smallest subjects.

For more guidance, I highly recommend Leslie Stroebel's excellent textbook View_Camera_Technique. It contains almost everything you need to know about selecting and using view cameras and lenses.
