Starting a new thread here, not wanting to hijack the thread you asked this in. This is a typical example of a lens picture. "Lens picture" border="1" /> Getting the lens clean is indeed the biggest challenge. Things I do, in arbitrary order: Clean the glass with a pure cotton Q-tip after breathing lightly on it Use a Q-tip to remove greasy dirt around aperture rings and other similar places Use something like a tooth-pick to remove dirt in crevices in the focussing ring, aperture ring etc. Not shown here, but lenses with a rubber focussing ring are a real challenge. When possible I take them off and rinse them in dish-washer solution, that takes away the skin grub often left on them. Stubborn grit is removed with the flattened plastic tip of a Q-tip cut in half. When I can't take them off I use a tooth-brush lightly dipped in dish-washer solution and brush it clean. Still some of my lenses still don't look too nice, have to experiment further. After I have taken the picture I inspect it on the camera's LCD screen, enlarged 4x, for any dirt remaining. Often, a dust bunny has landed on the front lens and I blow it away with a Giottos rocket blower and retake the picture. 30 minutes time spent on this is not unusual. Lighting is done like shown below. It shows you don't need a fancy studio to do this :smile:.

I've done away with the cloth that came with the light cube, too much hairy dust . I use two good-old Nikon SB-24 flashes, triggered by YongNuo wireless triggers. The left one is quite close to the cube and produces a fairly directional main light, it's set at 1/8 output power. The right one is farther from the cube and produces more diffuse fill-in light at 1/16 output power. The right flash produces about 1 stop less light than the left one at the place of the lens. The camera is a G1 and the lens is a Minolta MD Macro 100/4 (superb lens BTW).
