Have been using digital Leica M since the M8 came out . Really enjoy street shooting with M sized equipment . The limiting factor has always been ..higher ISO performance . I shoot color otherwise I would get a MONO and be done with it .
Every camera I have tried seems to have excellent quality up to ISO 400 and good quality at ISO800. Shooting at dawn or dusk requires decent DR and color is important . Generally I find at ISO 1600 I am fighting the trade off between resolution and noise . DR is crushed ,color saturation is fading and its hard to get a “clean looking” image . My hit ratio drops considerably as I have no margin for error either in focus or exposure .
In FF nikon DSLR no such problem ..as I can use 3200 like ISO 800 in my Leica . Only using this as a point of reference .
Interested in what others are finding or accepting as a trade off in smaller form cameras .
