Do > you agree? Yes I do. I don't know if I mentioned it, but the Sigma was shot wide-open and the Summicron, in that particular parallel portrait, was at 2.8. It problably would have looked a bit better at f2.0 in that portrait since the faster shutter speed would have given better sharpness. But it's a big hunk. Not heavy. It balances well, but it is big, no doubt about it. I didn't buy it, but I might. It's definitely usable at 1.4, at least around the center. Hope that made sense. Daniel
