Is the tamron sp af 10 24mm f 3 5 4 5 di ii ld aspherical if worth buying used?

Probably, if you shoot APS-C and want a wide zoom. This lens only works on APS-C bodies. On a Canon EF body it needs an APS-C model, and full-frame Canon bodies have no crop mode for it. On Nikon F and Pentax K, full-frame bodies can use it in crop mode at fewer megapixels. It frames like 15-36mm on a Nikon or Pentax APS-C body, or 16-38mm on a Canon.

The site doesn't list prices, so I can't say whether a used copy is a bargain. The general rule on buying used still applies: an older body or lens often gives you most of the value for much less money. Budget for a new genuine battery with any used body. If you're still choosing a system, your first camera covers how to decide.
