jeannette08, as for the cost, this would depend on where you are going to take it. ifixit does nto do repairs:-) but you can try and fix it yourself. It is possible that you get the lens error because your lens is of the track or otherwise stuck. Take a look at this site. It does give a f solution that yo could try first. Here isa great forum with some good answers, and take a look at this for the same error on a slightly different camera. Hope this helps, good luck.
