Re: Diagonal Streaks In Sky on Select Shots (NOT Posterization)

I had a hard time seeing the effect you are talking about in the long exposure shot but it is more noticeable in the second shot you posted.  It kind of looks like a very faded jet contrail in the picture.

If it were me I would take some identical(ish) sky shots with the Tamron and another lens then compare the two.  If they both have the faint diagonal light stripe then I would suspect the camera.  If only the Tamron does this then I would expect the lens.  Maybe the lens has an internal reflection that is causing this light streak?
