For those who have tried both of these lenses, all issues with autofocus and corner performance aside.. is the ability to focus that much closer with the 35mm f2 really that useful compared to the Sigma 30mm 1.4? I have the Sigma 30mm 1.4 right now, and it never leaves my camera. Hands down my favorite lens in my collection, but the whole focusing distance thing annoys me to heck. I'm just wondering if it is worth it to switch over to the f2. I'm also interested in the bokeh differences between the two.. any one out there?
