Just booked a trip to Austria to see 1 stop on the Four Hills Tournament (Ski Jumping) for January 2019. Since this is a bucket list item, I am likely to rent a larger lens and camera body. What do I need to look out for with TSA, Four Hills event staff and security services leaving Europe? Back in 2010, I took photos at the Olympics in Vancouver of the Ski Jumpers....the event staff didn't seem to care as long as I wasn't a 'pro'. Back then I had an XTi and the Tamron 200-500.

Also, what should I bring for gear? I don't want it to weigh too much. I was thinking of the 7Dii or the Sony A7iii with a Sigma 150-600 Sports.
