At noon time today, I went back to a Victorian house I had previously taken a shot of.
The original was with the DA 18-55 and todays was with my recently acquired DA 16-45.
While I could see a marked difference in the lens with the extra 2mm on the wide end, I did not seem to be able to duplicate the original.
The time of day, lighting (Partly cloudy - vs- sunny), shadows were all different and, come to think of it, I used spot metering as opposed to Matrix.
This judgement, of course, from looking at the result in the LCD and not on a full screen or print (could change everything).
What I learned? Sometimes you can't duplicate, or improve, work you've already done.
