I like the layout, with the side-by-side dials rather than front and back. Pressing the left button changes modes, and you can remap the secondary function on the fly by holding its button down. It defaults to ISO sensitivity.
The CL borrows a lot from the Leica M series, though I think it has most in common with the Leica Q.
It has a tiny status display on top that shows you the current shooting mode, shutter speed, aperture and where relevant, exposure compensation setting.
By making the top dials multifunctional and mappable on the fly, Leica could get rid of extraneous buttons on the back. A single press of the Fn button lets you change a particular setting; holding it down lets you choose a different setting to be the one-touch option.
You really have to hold it with two hands.
To keep the clean lines, Leica eschews such niceties as a USB port for charging. So not only do you have to tote the charger, you also have to tote the power cord, because it doesn't have built-in prongs.
But I would have liked titling or articulation, even if it means an unsightly hinge. (The plastic bar cutting across the top of the viewfinder eyepiece will not be on the shipping models.)
It's there because Leica didn't want to put an unsightly door on the side, which is annoying.
No, the lens isn't red. Sigh.
