SIRUI HA-77 telescopic extension arm 77cm - HA series

Also outside the tripod axis in the middle of the action

An extension arm is indispensable for shots with a camera position outside the tripod center. Especially for top down, macro, food or repro photography, there is no way around the horizontal arm.

The special feature of the SIRUI HA-77 is its telescopic function. The arm can be extended to 77cm (overhang 60cm) and is therefore extremely flexible to use. Rotatable by 360° and tiltable by 90° on both sides, almost any camera position can be adjusted with it. Thanks to the non-slip foam rubber handle, the jib can be operated safely.

Let yourself be surprised by the functions this compact jack-of-all-trades has to offer and how much it will make your photographic life easier.
