I want to shoot fashion, and am intrigued by the camera Objectives' market offer.Allright, if I have understood the situation,there basically exist Telezooms, Great Angular zooms, and Universal zooms-which are both Tele and GA. As long as I want to dispose of the largest focal range I can get (18-200) but only have about about 1500 dollars, is it preferable to buy three different objectives (18-35, 35-70, 70-200) or will just one work fine?

And if it will ,what do I want to purchase a zoom that is just a tele or GA for?Will they give me better quality in that particular function- in omparison with the Universal Zoom?
