I'm getting a weird cross hatching issue with ISO800 on the P45+ at night. Most of the cross hatching occurs in the out of focus parts of the image. I initially imported them in C1 Pro and was shocked to see patterning in the mid tones and shadows. I also processed the images in LR 2 and ACR and the files did not have cross hatching or muddy details.

Any ideas?
