I have found that my Sony FE 28-70 "Kit" lens that came bundled with my original a7 body (which I sold off and got a a7II), has turned out to be a real little champ. I've put it thru the paces at various apertures and focal lengths with test patterns and found it rivals my "G" and even Zeiss glass. Maybe I just lucked up and got a sweetheart here, but it's resolution is incredible. Have you Guys out there had good luck with this lens or is my situation just a fluke?
