There are two lines of Sony lenses - those for the DSLR-style fixed mirror camera, the A mount, and those for the mirrorless cameras, the FE (full frame) mount and E (crop sensor) mount. FE lenses can be used on E bodies, but will be a bit bulky and certainly expensive.
If our Sony users are aware of any hazards, please say so, but the biggest hazard I can see is that users might suffer severe wallet-deprivation from the cost of the incredible lenses. It's an outstanding range of optics.
