This is where I changed to the 18.5mm f1.8 lens. The 10mm would have been too wide for my taste. Stopped dows to f2.8 for a little more depth of field as I wanted more of the locks in focus. Small, fast and sharp and gives me a 50mm lens in 35mm terms. Quite nice but the system is still lacking in lens selection. I believe Nikon are planning on bringing more lenses onto the market for this system but I'll wait to see how it develops. not sure I'm going to keep the system right now and I intend to use it a little more as a take everywhere camera before deciding. I just wish the 10-30 would be a little better than it is, maybe I've got a dud one.
