Digital BW, The Print

Austin, I have Canon macro lenses, and also the 28-135mm IS Canon.

And I can tell you for a 100 percent positive certainty that the macro
lenses are sharper. There is absolutely no doubt whatsoever about this,
and it is consistent from image to image. The difference is very
noticeable particularly in closeups. The zoom is quite good at far to
medium distances, but the canon macros with floating elements are
better. Even at infinity. For closeups, the macros are much better.
