Well...I came across a really good deal on a 300mm f2.8 VR that the owner had bought at the end of January, but had to sell due to hardship. Too good to pass up so I jumped on it. So...any tips on shooting this lens? The biggest lens I had prior is a 70-200 f2.8 VR. I also bought a Gitzo 3530S and RRS BH-55 to hold it in place. Should this work or will I be wanting a side kick or some kind of gimbel (I have no clue about these). Also think about getting a lens coat to protect it while shooting critters. Any suggestions, hints or comments welcomed! Thanks!
