An unboxing video from YouTube member Michael19801234 of the latest Opteka SteadyVid Pro Video Stabilizer. The adjustable arch is a design used in some stabilizers to change the weight ratio - more or less bottom heavy. The lower the weight from the Gimbal, the more weight it should be able to support. Judging by the weights and distance, it should have no problems flying the 5lbs. it claims. Currently the Amazon product page has a special promotion for the free cleaning kit.
Opteka throws in a new Video Camera stabilizer with a fully adjustable top stage and upgraded 3 axis gimbal. Looks pretty similar to the Steadicam Merlin. The lower weights (stainless steel?) look almost exactly like the ones used in a real Steadicam Merlin (seen here), and the specs say it can handle up to 5lbs of camera.
Unlike the Merlin, it does not appear to fold up, but adds an adjustable front counterbalance weight. Of course nobody should expect the build quality to be up to par with a real Steadicam Merlin, but how well will this new stabilizer actually perform? The Steadicam Merlin will run you about $800 dollars (click here), and the new Opteka SteadyVid Pro runs just under $180 (click here).
