Just to confirm, are you talking about the GW-4? That's the correct wide angle converter version for the GRIII. I haven't done side by side tests, but no, I've never noticed obvious softness, just checked a few images in my library. I tend to shoot at f4 or f5.6 with it for depth of field, I don't think I've got one shot at f2.8 to check. I do wonder how much the alignment between converter and the camera changes over time, since the adapter and bayonet on the camera are plastic, and if that can degrade image quality.
