An interesting and well written take on the M Module on Luminous Landscape. I concur with most of what's been said. It's spoiled in part for me by a couple of things - "The M9 is the only current M camera from Leica." and "Finally, it musn't be ignored that while GXR-M can take all M and compatible lenses (and only these), the Sonys take not only M compatible lenses but also Sony's E series autofocus lenses, Sony's full line of A series lenses with Phase Detection autofocus via their new LA-EA2 adaptor, and a wide range of other brand lenses as well via third party adaptors." Both are untrue. The first sounds like a straight oversight but the second is misleading. The GXR also takes "...a wide range of other brand lenses as well via third party adaptors" - I should know, since I am using both Leitax'ed Leica R and Nikon lenses on mine with a single Novoflex adaptor. Beyond that it is a more than useful review.
