>>3045247Comparing zooms and primes isn't really fair. Especially when some are on FF and others on crop.
While the aperture settings suck on the 28-70, it is quite sharp in the center, and even the corners when stepped down. That said, while a good enough kit lens, it isn't anything I'd go out of the way to buy. Especially not if I had a crop sensor.
What about the SELP18105G? Probably his best option, though pricey.
