Sorry everyone - I bet you get fed up with me and my questions!!
Following advice on the forum, I figure I'll get myself a decent tripod - the one I've got at the moment is pretty useless. I am amazed at the range and variety of tripods on the market - but also with some of them you have to buy the head separately!
My kit is a Nikon D90, Tamron 70-300mm and Sigma 150-500mm so I'm looking for a tripod that can take that kind of weight. I like the look of the gimbal heads but I dont think I can afford one of these ...
So here's the question - which tripod?
Any help greatly appreciated.
