That digital correction thing doesn't seem lossless

Tried canon 750D plus 15-85 at 15mm versus Sony a6000 at 16mm corrected or uncorrected Canon is by far better, I can post 100% crops here if you want. But we are comparing a tiny kit lens versus a decent 800$ lens. So it's an unfair comparo results are to be expected.

I can try versus kit 18-55 if you want

 

If you have that 16-50mm lens - its only value prop is size really.  All the rest is ... meh.
