...A prime will almost always outperform a zoom...
In that case I might have to review my verdict; The da* @ f/5.6 at least matches the FA50 @ f/4.0 in crispness/sharpness. I might have been thrown off by bright light and hard contrast; my DA* suffers a lot from purple fringeing. Less light and it gets better.
One bad of mine: the FA is not the macro but the 1.4. (Sorry)
