I need a tripod that can look downward - 90 degrees - to snap photos of coin-size objects. I can place objects on a pull-out leaflet of a desk ~3 feet (1 meter) above the floor. Tripod should also be capable of taking portrait shots. Weight is not a factor, but awkwardness-of-use is a negative. Currently looking at a SLIK U-5500 or a Sony VCT-R640, but uncertain of their capabilities. Suggestions?
