I think Leica may have found the ideal formula here. The reality is that most people gravitate towards a "favorite" lens which is on their camera all the time. Since most people are either "35ers" or "50ers" hitting the middle is brilliant.
Putting in AF, leaf shutter, EVF, OIS, macro, weather sealing and arguably the best optical quality available - APO from Leica - checks sooo many boxes for many that this camera may well be the absolute beststeller in Leica's portfolio and satisfy many photographer's needs for the ONE great tool they can take along anywhere.
The fixed lens limits you, yes, but then again it frees you because this is all you have to work with and that's liberating.
Over time you just fall in love with it, I suppose because you can take it anywhere and focus on brilliant photography.
Really great product. Imagine a fixed S4 with a 60mm lens or so.
Wonder if we'll see a Q3 43M ...
