Is it slimmer? YES. Holding it gives the Leica film body sensation.
Easier to look out of? YES. The new 0.72 finder is wonderful.
Lighter? YES. Feels close to the M262.
Better menu? YES. More like the Q and SL in terms of appearance and function.
Better with less buttons? YES and NO. Never had a problem with the buttons before but the less buttons seems ok.
High ISO? HELL YES !!! Finally, the image above isn't anything special except it was shot at ISO 10,000. NO previous M can do this.
Detail retention? YES. I loaned my new camera to a few of my colleagues and some of the shots were well under exposed. I pushed the file 2, 3 and 4 stops. Not only was the subject looking good, there wasn't any banding or color issues. Just looked liked a properly exposed shot.
New sensor and processor better? Oh YES. Colors, white balance, noise reduction, etc... all was dramatically improved.
Conclusion....
So far this new M10 is living up to what I wanted in a Leica digital rangefinder. The high ISO is an important thing for me and all the previous M's (except for the Monochrom) fell short of what I wanted.
The M10 just feels good in the hand. Just like holding my M3 or MP film Leica's. Going to do some black and white shots with the new M10. If things work out... who knows, my previous stance that the Monochrom goes no where might be moving on to help fund perhaps another M10.
I have NO regrets for selling off nearly my entire Nikon digital set-up.
