Hi Gary, First it's really good to see you! Yes, I feel the same about the a6300, my favorite camera to date and I have Canon 5D with L Series glass. The 6300 was intended as an aerial camera purchase but now I've decided to dump Canon altogether.
OK Lenses: I've spent my way into some knowledge here lol (Bought some duds and re-sold) So I can save you some money. Do NOT buy the Sony 16mm Pancake... Highly disappointing pc of crap. Do NOT buy the Sigma 19mm ART Highly disappointing pile of crap!
What I landed on for aerial and wide gimbal in general is the Sony 10-18mm zoom. Fantastic lens. :

With the crop factor it gives you 15-27mm equivalent so it replaces your old standby 16-24 from the Canon world.
Sharp as a tack and just beautiful color rendition blah blah.. Search YouTube for footage of it on the 6300. It has the added benefit of being lightweight as all heck, which is fantastic for aerial.
For a general zoom I settled on the Sony G 18-105 mm as it is the sharpest zoom they have in that range. It rivals my L Series 24-70 at half the cost. (And a much longer reach when factoring the 1.5 crop it gives you about 24-150 which is a really nice reach.) LOVE this lens! So sharp :

THEN because both those lenses are f4's (that's the only downside to Sony right now.. shy on the fast glass). But these are for outdoor use anyway for me. SO the next one I bought is the Sony 50mm F1.8 which is there "Plastic Fantastic" equivalent. Cheap, sharp and light. Gives you about 75 mm which is great for portraits and fast at 1.8 for blurred backgrounds which is essential for portraits.. And it's great for indoor shoots at concerts etc.

The other thing to know about Sony Lenses is the naming convention. Crop sensor vs Full Frame. The "E" mount is standard body mount on the a6300 and A7s etc. HOWEVER the lenses are denoted as either "E" mount or "FE" mount. "E" mount is for crop sensors, and "FE" is for Full Frame.
