This is one of the heavier metal Adorama macro rails made in Japan not the lightweight plastic one from China. Very minimal signs of use. Always shot with in the studio, never outside. Holds a 1DMKIV with a 180mm macro or the MP-E65mm macro lens rock solid even at odd angles. I had the best results when matched with a geared head due to the weight of my setup. $120 shipped and PP'd Con US only.
