I was processing some shots from a recent outing and noticed a strange line in some of the shots. I see it in some but not in others, though it is hard to notice even when present. The line is present in the original raw file, but easier to see with heavy contrast adjustments.

gear: K20d with smc K-50mm f/1.4

I was shooting in cold winter conditions. Could be sticking aperture? Sticking shutter? Sensor defect?

I don't know if this is a sensor, shutter, or lens issue.

here's the shot showing where I cropped


and here it is cropped in with extra contrast to really show it
