I already have a "standard" tripod which is very good but unfortunately is not very suitable for traveling. For that reason I started looking for travel tripod, products were found suitable but with exorbitant prices. Determined to find a reliable solution to my problem, I finally found the Manfrotto MTPIXI-B, all the comments indicated that cétait the solution I was looking for, and I can confirm! :) This is Exhibit déquipement with best quality / price in my camera bag! With a Canon 40D and Canon 100-400L Manfrotto MTPIXI-B ensures its function without any doubt! If you need a quality tripod to accompany you on a trip (goes smoothly controls of the airport) and you summers ready to work with these size limitations, there is no better way!
