I am thinking of buying a nice tripod setup for my 600mm. On previous occasions I had taken just a cheap aluminium tripod but results were not so good as there seems to be some vibration making the pictures a little soft (especially with 2x multiplier), and the lens seemed way too heavy for what I had. Now migrating birds are in and am planning to get some pix as I am now better prepared with a 5DII (used 40D previously). What would be a reasonably good setup that is not too heavy, and where can I buy it? Thanks in advance.
