I found a Samsung 20mm f/2.8 pancake lens on ebay for a good price, and while I still haven't decided whether or not to keep the NX200, I thought I would give it a try.
A few test shots indicated that it was a decent lens. I'll try it out properly soon. It is however very small and I imagine if I wanted, I could put it in my pocket!!
Looking at the camera pictures I think I need to get the duster out!
