Combination zoom lens as alternative to 18-55mm & 55-250mm lenses for my T3i?

[msilvers50]

I have a T3i with 18-55mm and 55-250mm lenses.  Switching lenses while sightseeing is a nuisance.  The shorter one is needed for close photos of museums, galleries, close up sites, ourselves and our friends, etc.  Longer lenses are useful for many outdoor city and rural/mountain shots.  Is there a reasonably priced combination zoom lens I should be considering?  Is there somewhere I can sell my current lenses.  My T3i and lenses are less than a year old.  Thanks.

There are a lot of options out there for "superzooms" if that's what you're looking for.  Here a decent article on them and explaining some of the pros and cons:

I see a lot of recommendations for http://www.fredmiranda.com/ for buying and selling used.  But I don't know that you're going to get very much for those kit lenses.  Might be difficult to find a buyer too, but you never know.

Most photographers say to buy the best "glass" (lens) you can afford because they will last a lifetime. Good lenses are not cheap, so my advise would be to keep what you have right now, and learn all you can about them and the aspects of taking photos. While you are learning you can investigate the different lenses, determine what type of photography you are really wanting to take, and so have a better idea of what you NEED in a lens. Hope thgis helped a little.
