increnator he wants zoom in 10x 20x term ....its normal for newbie to ask this question and answer is simple
hmm you can say that after you buy 55-250 you will have 18-250 range in lens thats roughly equals to 250/18 = 13x zoom
in DSLR world we dont count zoom in x but its always about mm ...like what we see is around 50mm soo anything more then that is magnification and anything less then that is wide angle
