Erwin Puts take on the X1.
His final observation: "The imaging engine of the X1 (lens, sensor, processing) delivers impressive results that are close to and even equal to the image quality of the M9. This conclusion is based on a test where the parameters are identical. The decision to use only a part of the sensor size of the M9 to be comparable to the sensor size of the X1 sets the M9 on a roughly 50% disadvantage. Granting this advantage for the X1, the performance is without doubt Leica-like. The endeavor to give the camera a shot of Leica DNA however is less convincing. The feeling of engineering quality is lacking and the decision to overload the camera with consumerism-items distracts from the basic simplicity and efficiency that all true Leica cameras possess."
