I just got my new Opteka 23" Camera Slider yesterday and did some test shots at the skate park. I'm still a bit shaky, I gotta practice getting smoother shots.
I know there haven't been many videos that show this slider, so I hope this helps!
Shot on: Canon 60D, 18 - 135mm kit lens, Samyang 8mm Fisheye
