We don't usually use a second (objective) lens in photography. It's sometimes done in astrophotography, though. Usually, though, photographic lenses just use one (compound) lens with a specific focal length. When you mount two lenses nose-to-nose, for extreme macro photography, you're doing something similar to a telescope with an eyepiece (objective) lens. TTYL, DougF KG4LMZ
