Also if no sensor cleaning is included with gxr, it is a possible problem for lens changers. It is good to have more serious camera options
The 2nd half of 2011 sounds like a great year for people inflicted with GAS! We've got the new Pens, new Oly lenses, new PL25, the NEX7, the A77, and now the GXR Leica module. Pretty cool!!!
