“What the difference in the 50mm f/1.8 prime lens vs. the 50mm f/1.8 optical? Other than the 30 ish dollar price difference?”

• The cheaper of the two (SEL50F18F) is for full frame (like the Alpha a7). It’s tweaked for that sensor (although will work on the APS-C sensors), and relies on the in body stabilization of the full frame cameras. This lens (SEL50F18) is designed for the a6000 series APS-C sensors and includes OSS (Optical Steady Shot) which is very helpful in low light (where this lens shines) as the a6000 and a6300 lack any sort of stabilization in body (although the a6500 offers stabilization - this lens is made for the sensor, whereas the other lens would produce a different focal length - I believe 83mm).

• the FE 50mm 1.8 doesn't have OSS, that's why it's cheaper.
