hi everyone, i need some more experienced opinions on tripod choice. i think im going to go with the brand optex because i have $100 voucher for a store who sell optex and manfrotto but the latter is over my budget. heres a site with the models on it... http://www.dirtcheapcameras.com.au/store/brands.asp?id=38 all those are in my price range, so should i just go the most expencive (OPTEX Photo Video Tripod - T565 ) in this case? is table top for use on a table? ie it doesnt extend very tall... if it helps, the tripod will be supporting a D50 with a 300 zoom lens. thanks in advance for any help you can give.
