It's also not the real story. There is a difference in image quality between
the two lenses, but it's not a "night and day" type difference. The 28-135
is a very reasonable lens, but still has a long way to go to come near prime
or "L" glass quality. Again, "not coming near" does not mean *that* much of a
difference.

Besides that the difference is really not *that* big, web based comparisons
are always problematic and tend to even things out. With everything short of
a drum scan, the fine differences which will result in big differences in
large (bigger than 8x10") prints, are mainly lost in the scanning process.

You really don't have to feel bad for her, as long as shed doesn't try to
produce big exhibition prints ;-) Contrast is another story and the differences
are more easily seen even in quite small prints, also chromatical aberrations.
But these are not things that pop out on you from a cheap 4x6" print.
