At present I am using a 14-45 kit on a E-500, but the time has come to upgrade. Has anyone had the chance to compare the above 2 lenses? Obviously the Sigma is Ł100 cheaper but with 2.8 throughout and Macro is it it a better lens?. The 14-54 Zuiko has always been seen as the obvious upgrade, and being a Oly, has higher connotations of Quality. As an aside I've just bought a 70-300 Zuiko and it is a cracker, the purpose of this question is to try and get the highest quality of lenses (on a budget) through the new 9-18 Zuiko, standard quality zoom and my 70-300, so as to have a 3 lens total coverage.
