I began using Leicas in 1969, first using a M4 in 1973 and buying my first M3 & M2 in 1974.
Various CaNikons came and went through the years, as did different M bodies and lenses. Whether I was using Canon or Nikon for my SLR needs, there was always a Leica or two or three in my kit.
Then came 2003 and my newspaper went digital. The film SLR's were sold, but the core of my Leica kit went into the safe. I was for a time, using only DSLR's.
I retired at the end of 2008 and in 2009 returned to my Leicas, the tried and trued M6's for film and a pair of new M8.2 bodies for digital.
The M8.2 is in its core a Leica, but with one glaring asterisk, the crop factor which significantly redefines any lens. You can't discard the outer projection of a lens and retain its essence.
Last October, the realization the M9 would go away with the introduction of the M 240 prompted me to move-on from the crop sensor bodies to the full frame M9. With the M9 I finally had the camera I wish I could have had when my job mandated I go digital.
With the emergence of the Type 240, it became obvious to me that the M9 and M-E would be the last M cameras with the pure mechanical rangefinder and less complicated approach sans video and live-view. I prefer the esthetics of the M9-P to the M-E so that is what I use.
I waited a long time for this camera and in just less than a year, feel I am finally getting a full appreciation of its potential. Integral with its potential is also using my rangefinder mount lenses to their full potential rather than cropping off a substantial portion of the image.
I'm not bothered limiting my ISO choice for the M9 to only 1600, I can't recall ever using any film in my various film Leicas rated any higher. I know how to make images to my liking in any light with an ISO rating of 1600 and lower. If I had any real issue with the ISO range of the M9, it's that I can't easily do ISO 25 or even 64. That's life.
I am not a videographer, I don't want my cameras cluttered with such a capacity, I will never use it. The optical projected frame masks of every Leica M camera up through the M9 and M-E are a comfortable constant, I see no point in changing now.
I have no interest in reinventing the basic rangefinder camera with an electronic VF or live-view on a rear screen. I have no interest in moving-on from a full frame format for my rangefinder lenses.
I like my pair of M9-P bodies, they are the closest thing to a digital M6. I waited a long time (July, 2003 to the end of 2012) for what I consider the proper digital Leica. My M9-P cameras (and associated lenses) will be the very last photographic items I might ever sell, hopefully they never will be sold, hopefully they will also be supported by Solms for many years to come.
