I own both too, and can unequivocally state that the 19 (of which I've owned 3 copies) is inferior to the 30. They might be pretty much the same on m4/3, where the worst part of the 19's image is cropped away, but they're certainly not on the NEX. The 19's center sharpness is as good as the 30's, but it's got noticeably worse CA and substantial field curvature that leads to border softness in most situations.

It's still a great lens for the money, though (the older, cheaper one at least) and is kind of a no-brainer purchase. And if you've got a NEX-7 in particular, the 24mp means you'll need to print really large before the field curvature becomes apparent.

That is your subjective opinion, but why did you need three? Was it a bad  ger Cicala said that the 19 and 30 on the NEX-7, tested equally.
