The Benro DJ90 is a lightweight treadmill for single leg stands. With a camera on the monopod head you can take portrait photos quickly and easily. The tripod head has a handy bending system to tilt your device up to 90 degrees. You lock the DJ90 with a rotary knob, so that the angle remains the same. Of course you can also shoot straight. Use the built-in spirit level to straighten the camera.
