I've got to post up some examples, but I really like this lens. It's very affordable, lightweight and for non-critical uses, it's very much up to the task. It keeps the a7 "compact" while delivering that "full frame" look better than say an a6000 w/kit or m43 with kit.
I always keep at least one basic, auto-everything lens I can take to family events. I need one lens where I can put everything on auto and hand the camera to my wife, and things will just work. She's a people person when it comes to photos, and I am not so much. It works.
I think the 28-70 will be that lens, which came with my A7ii a few months ago. For that purpose, I think it will be fine.
Pretty impressed with this kit lens. I usually sell the kit right away, but I think I'm keeping this one for awhile. This picture was a heavily cropped jpeg but still provided a lot of detail to work with.
FE 28-70mm F3.5-5.6 OSS
SOOC jpg (almost - slight vignette added in snapseed) with pleasing results at f/4. I'm not saying this lens is anything special compared to some of the pricey glass in the system but it is useful, sharp and light.
