The Leica CL was a cheaper Leica M and did well, the new Leica CL is a camera I have been waiting for Leica to produce for the last few years and it excites me greatly.
The Leica Vario was marketed as a mini Leica M, and because of this if failed. It was a good camera and fitted a niche well but because of the marketing people were expecting something it was not.
The Leica CL takes the best parts of the Leica X series, Leica Q and Leica TL and produces a real photographers mirrorless camera.
If your looking for a new camera then an Olympus, Sony or Panasonic mirrorless camera may be better but if you want a Leica and to be able to use Leica’s TL and SL glass plus all the old M glass and even R glass in a small modern mirrorless camera then its the one to pick.
I can imagine a lot of older photographers whose eyesight is now getting the better of them, trading their Leica M’s for this and still being able to use there favourite glass collected over the years.
For many photographers its what they expected the Leica TL2 to be.
