IQ is surprisingly good, considering the barrel wobbles a bit when focusing. AF mechanics make manual focusing a bit touchy, and the AF is borderline useless because of noise and inaccuracy.
Can't say much about the build quality. AF apart, I'd say not unlike the Sony 18-70 kitlens. Metal mount makes it feel mounted a bit more solidly.
Separate adapter for true 1:1 macro is a hassle to get on/off all the time, prone to get dirty/lost, but does not affect IQ as much as I thought it would, much better than generic macro diopters.
Plenty sharp when stopped down, an ideal starter macro lens if you don't have the budget. Doubles as a decent portrait lens.
