I have had the BH-40 with the lever release for a while now. I haven't used it much due to work. Although in the time that I have used the ballhead, there's something about the lever release clamp that doesn't seem natural to me. Is it possible that I'm using it wrong? Are there vidoes online demonstrating how to effectively use the lever release clamp? My previous ballhead was the Markins Q3T, but that had the screw knob clamp. I'm starting to regret not getting the BH-40 with the screw knob clamp.
