The R2004 Aluminum Tripod with E-20 Ball Head set from Sirui combines the lightweight and portable R2004 aluminum leg set with the versatile E-20 ball head with Arca-type quick release system to form a compact and lightweight tripod that is equally at home in the studio or on location. Sirui R2004 Aluminum Tripod The 3.7 lb R2004 Aluminum Tripod from Sirui is a 4-section support with aluminum-constructed tubes and a twist-leg lock system. You can disengage the locks; therefore, the legs are extendable, along with the rapid center column, to a maximum height of 64.2". With variable leg angles, you can splay the legs out, so the tripod drops to a minimum height of 15.2". Even with the low height, the center column is reversible to get closer to the ground, which is ideal for macro photography. The unique wing-nut design locks the collar to keep the center column at its required height, and the tripod folds to a length of 20.7" to easily transport or store away. The rubber feet retract back to expose the stainless-steel spikes to further stabilize the tripod on icy surfaces or soft terrain.
