The 210 is quite possibly the most useless lens ever haha. Can't couple to the rangefinder, slow as the internet was when it was introduced, minimum focus distance is like 25 feet or something stupid - so you can't even use it for headshots, and it costs as much as a Leica body.
Really, if I had that camera, I'd just about only use the 43mm, because that's what that camera is for - Best portability:Image Quality Landscape camera you're going to find, and has perfect glass.
Also, the panoramic adapter is fucking SOLID.
