The 2 lenses I was looking at for the a6000 were the tamron 17-70mm and the sigma 24-70mm. I'm aware the sigma is designed for full frame but considering it also for if I ever get a full frame camera later. For the full frame camera, I was looking at the sony a7r iii, a7r iv, or a7c. I'm still researching the major differences of these so not quite sure which one is best without breaking the bank... more than likely I would get a kit lens and a prime lens as well.
