Pic related is measuring how many distinct horizontal lines can be resolved by the lens across the full vertical height of the sensor with at least a 50% contrast difference. The more lines, the greater the resolution & sharpness.
Sigma on top, Sony kit lens on bottom.
As you can see the Sony just destroys the crop lens, at this 50mm equivalent the Sony kit lens is managing just shy of DOUBLE what the sigma can do in the middle, and even the border measurements remain higher on the cheap kit lens. And a cheap pro lens like the tamron 28-75 2.8 isn't just massively sharper than the Sony again, it's also a stop faster in real terms than the sigma, allowing you to take photos in HALF as much light, and it's only like $200 more than the sigma.
Crop is a false economy, this shit has been repeated to you time and time again in this thread. Are you just a bit thick and thought you knew better than the people you asked for advice?
Oh well, enjoy shooting your brand new full frame gear!
