I'm a huge Zeiss fan but have read nothing but great things about the performance and build quality of the VC 28/3.5 and have one on the way. For faster I'd more likely consider a Zeiss but not a 3.5. Generally I have not been that enamored of VC lenses having bought and sold a few (40/1.4, 35/1.2) but the images and accompanying comments I've seen online from this lens are phenomenal.
