Tamron 18-200 E-mount or Tamron 17-50 A-mount + LA-EA2 ?

gfrensen the reason I want the nex7 is quick access to settings. Since I’m learning I change a lot of settings to see the results. On my C3 it means a lot of menu digging.

My problem with the kit lens is that even though it is decent, where I live it is quite expensive (close to 400 USD) almost the same price with the 17-50 and I was thinking that I might get much better IQ this way

I am aware of the primes but as I mentioned I need a “walk around” zoom because sometimes switching lenses is not convenient
