Lens Comparison

Hi

I've been looking at the Sigma 105mm and the Pentax 100mm. Currently the Pentax is £70 more and I was how much better is the Pentax? Has anyone seen results from both of these or knows about the differences?

Thanks, Paul

If you mean Sigma AF 105mm f/2.8 EX macro DG vs Pentax SMC-D FA 100mm f/2.8 macro I found them equally good on IQ (excellent that is) but the Sigma seemed better built. I bought SIGMA.
