Thinking I may have made a mistake.

OKAY as the subject line states, I have made a mistake in my purchase. The camera in question is the Sony Alpha SLT a35. It is obviously entry-level and the second-generation of the SLT series. I felt I was happy with this camera but it seems that vignetting "light fallout" is the norm with the "lower end entry-level" of the lot. I have read that only the higher end of the SLT's can compensate for vignetting on selected lenses.

So my problem is this, do I keep the camera and accept this inconvenience? I see NO REASON that the kit lens should also be vignetting. The moment I do any postprocessing, the light fallout becomes more apparent. What should I do about this? Do I keep hunting for a lens that will work with this camera at the wide end? Or am I missing something that could be a solution? To those of you who are helping "Brian", I'm sorry that I'm complaining again. I get vignetting regardless of the time of day!
