RX100 sharpness comparison

Hi,

since I wasn't quite sure if my RX100 is as sharp as it should be I compared it with a second unit today. Here are the results (8 images):

The last 4 are most relevant since they were done in manual mode using the exact same settings (f1.8 and f4.5 for both units).

Any comments? I won't tell you right now which images are from which unit but I indeed feel that my unit is less sharp. AF was set to middle for all images, btw.
