I've been looking for a tripod to use with my 55-300mm (1.28 pounds) and tokina 11-16mm (1.23 pounds) on my d3100. I'd like the the smallest possible tripod that won't cause it all to topple over. All of the travel tripods that I've seen are way too heavy and large for me to deal with. I'd like something about a foot long. Does this exist? My stuff is over the weight requirement for the small tripods that I've seen. Thanks!
