I hadn't used a 28 much before the GR but am now enjoying the process of moving closer and trying to fill the frame. It's just a different way of working. In street shooting I find I'm also much more attentive to the setting. I now find that, if I were using a 35 or 50, I often would not have gotten the photo I wanted. The camera also has the most pleasing BW rendering of any small camera I've owned.
Good examples John!
