A seller on eBay has the 50mm e mount Sony Prime lens for $198 with a 64 GB SD card, and with the 15% off coupon, the price comes down to $168.30. Coupon code is PLAN2SAVE and only valid in the app until 1PM PST today.
I have the same lens on my a6000, and it works pretty well, the focus motor is a bit noisy though.
