I am pretty much convinced I need a new lens, because I consistently find that I am unsatisfied with the sharpness of my pictures. :(
So, which to get? I'm leaning toward either the Pentax 100mm WR macro, (that lens is beautiful) or the Sigma 28-70 (a little more practical, but not a whole lot of trusty reviews to accompany it.) Unfortunately, the sigma wouldn't satisfy my macro desires, unless I got some more accessories of course. Plus my thriftiness is also in the way :/
