Bob, jip, its the Leica, which is way tooo expensive, but as I already have it and I knew it works well, I use it on the M. Cheaper ones are available. But on the M as far as I know, you cant have fill in flash and viewfinder...better then to have a look at something like a X100s..which I really like on paper, but also twice the price...
Tom, yes if you have to buy a standalone camera, depending on your type of photography, I think there are very good alternatives available. For me it was a massive reduction in price AND the fact that I could use it as a backup in that all my Canon stuff can be used with it. The thing is, my 5D2 has never once let me down since 2009, and therefore it didn't make sense to buy something like a 7d or 6d as a backup. I just need something that can help out in an emergency and not take up too much space in the bag, and it was Cheap! Bonus is that with the Optical viewfinder it all of a sudden becomes more user friendly and I carry it with me everywhere. I will have a follow up post with my experiences(or not) in the street with the M...(almost sound Leicalike
