Arne,

The M7 is built like a tank. After 4 years dragging it all over the place, including two hiking trips to Israel, I would have no qualms recommending it. The 50mm lens is amazing. I like it better than the 43 as I think the 43 is just a bit too wide.

I have only used the 67 once and can't speak to it but I love my M7II.
