Important to remember is what you want out of photography. Are you into sports, nature, macro, portrait, happy snapper

etc etc.
I found that lenses that come bundled with a camera are generally cheap and get you started right away using the new toy. After all, camera manufacturers are not about to give too much away! ;-)
What I call 'long range' zoom lenses, such as your 55-250 are a compromise, then again, most zooms are to one extend. If you think about it, here is a piece of glass that is trying to cover all those focal lengths, something has got to give.
Usually they are not really good in the lower end as well as the top end, depends on the brand and model and they don't normally offer you a low 'f' stop.
So we come back to what I first said, what is your main interest in photography, as this should help you decide what type of lens to get and will also help members here to give you more accurate advise.
Whatever you decide, always try and buy the very best you can afford and when you can't afford it straight away, wait and save up some money, don't make the mistake of getting a less superior model/make lens because you are impatient.
And finally, as has already been mentioned, practise practise practise and then practise some more. :sillysmi:
