Leica equipment is always expensive
But always XXL quality
My IIIg is exactly same measures and weight as my IIb, but the IIIg finder is far better!
My M3 is bulkier than the IIIg.
I have a collapsible Elmar f2.8 5cm on the IIIg a lens that is slightly softer than Summicron but still a remarkable lens. Together, body and lens are of the size I can carry in a pocket.
