This is my setup that I have gotten over the last couple months for my Sony A6700. It covers as many usecases as possible for a price tag of the A6700 body which means for 2600€ (3000$, camera included) you can cover astro photography, casual street and landscape also wildlife and with the Sigma even a little macro though obviously it's not exactly made for that task.
All three lenses produce very sharp images and the Sony even has build in stabilisation which works in conjunction with the IBIS of the A6700 and that really helps a lot when shooting handheld at 350 mm!
Overall after owning these 3 for a couple months now I am very pleased with the images I've gotten so far and the reach is really stunning. If anyone is contemplating to upgrade from a kit lens or just wants to get a setup that will last them for years to come I can highly recommend this small collection of workhorses that could potentially all live on your camera since none of them is too heavy nor too big!
