Tamron 28-75 was a great entry lens for me.Just my old 70-200 f4
The rest are my APS-C lenses.
The new Sigma one is nice but it's heavy.
You can grab the 50 1.8 for cheap. It isn't particularly sharp and it hunts a lot on low light and is loud, but I've used it with great results before I purchased the 35mm 1.8 (that's on my camera most of the time).
85mm 1.8 is a sharp and great lense, but you're also good going with the samyang/rokinin 1.4 at 85mm and 35mm for the price of the Sony 35mm.
Just look at your lightroom and see what focal lengths you use and pick up any of those options and eat!
