My interest is wildlife and bird photography with my new (to me) Oly E-PL2 and Panny 45-200mm zoom lens. Yes, I realize this lens does not have great reach for the subject, and hope to add a Panny 100-300mm when the bank account allows it. Results so far are okay, but it's winter, so I haven't been out and about that much. I recently saw a semi-pro bird photographer speak, and was impressed with his DIY setup - a shoulder rig that allows him to quickly pull his camera to a shooting position, aim, and take the shot. It looked simple, light, and easily carried when slung down at the waist. Has anyone else done such a setup without spending much? I've seen the Stedi-Stock and another setup using the Manfrotto 361 and a pistol-grip, as well as other slicker setups at higher prices. But I haven't found much comment on such things in the forums here. Has anyone found found such setups beneficial, or are they just unneeded gadgetry? Thanks for any insights/help.
