My walk-around lens is the 70-300mm F/4.5-5.6G VR ED. It doesn't have the wide angle coverage you maybe looking for (or not). At a price of between $300 Used - $500 new. But the prices of the Sigma and Tamron lenses are on par, price-wise. If your needs tend to more wide angle, then I recommend 24-85mm F/3.5-4.5g lens at a price of $250.00 used, or $450.00 new. Both have garnered the "must have" lens status from the 'Angry Photographer'. If you are not familiar with him, look up his name under 'Google Search' engine under Youtube. Once in Youtube use the name "Theoria Apophasis" and the lens you are interested in (his real name is Ken Wheeler). This will give you more information than you can shake a stick at (he tends to get rather verbose, almost a rant, but he is thorough).
