This set has really improved my Lumix camera. Especially when shooting when the sun is low in the sky (perfect for low light conditions and hideous glare). Now, however, the barn doors allowed me to shoot from previously unreachable angles. However, stability is still an issue for me. Because his current setup allows for too much direct loading. Mainly because I still haven't found any equipment or proper means to balance the shoulder system. PS - it would be nice to indicate thread schemes.
