DxOMark tested the Leica C compact camera – this is their conclusion:
“With the stabilized zoom and EVF it’s an appealing camera but while the Leica C is a good performer it struggles in comparison with similarly priced, albeit larger sensor rivals, particularly in low light and at high ISO settings. As a compact camera it’s an attractive option although it looks expensive when compared to those models. If the badge isn’t important the functionally equivalent Panasonic can be had for around $200 less and has similar sensor performance, though it, arguably, struggles to match the Leica C’s elegance.”
