Hello all -

I just purchased the 24-105L lens and I have a question. The lens seems soft on F/4. Maybe one of you out there can judge if this is the case?

I have attached a screen shot of a crop of the two photos, shown in actual pixel size.

Left is F/4, Right is F/20

I placed the camera on a table and used timer mode to avoid any shakes. Both are ISO 100. Shutterspeed 1/30. Focal length 105. RAW.

Thank you in advance.
