Hi Billster,
I'm not clear from your original post, and the discussion so far, whether I've really understood the pictures you want to take with the new lens you choose...
You say you want to be able to shoot macro subjects, then seem to give your ship models - 12-24 inches long, 4-24 inches tall - as a more specific example.
Do you want to take extremely detailed pictures of very small parts of the ship models - e.g. rigging detail? A macro lens will enable you to place a life size image of parts of the models on the camera sensor - taken at the closest focus distance, giving 1:1 magnification, something that is 15mm x 10mm on a model will occupy the same area on the camera sensor. In the case of the D3100, this would occupy almost half of the image frame.
Apologies if you already know this... I just wanted to be clear that was why you were thinking of a macro lens?

Ian,
Apologies for the slow response. With ship models as the subject, I'm trying to find a lens that will allow me to:
- Take crystal clear close-up photos of details (e.g. zoom in on rigging details)
- Capture the entire ship clearly when shot broadside (so shallow depth of field?)
- Capture the entire ship clearly when shot from stem to stern (so deep depth of field?)
If I had to pick, my emphasis would be on the first item above, but my hope was the 40mm lens referenced above with a tripod and a light box would cover all three bases.
