These kinds of small issues that plague consumers are rarely considered in
reviews. While some of these design flaws may be significant they just don't
come up in reviews that are focused solely on image quality.
Even more to the point is the suspicion that reviewers get cherry picked
cameras/lenses that are not of the build quality that the consume can
expect. How else to explain the frequent discrepancy between lens reviews
and what users actually experience?
I'm looking at the rubberized side caps over the electonic ports in my D80
and wonder how long they would last if frequently used.
