Are you serious. This would piss me off. If I was traveling all the way to China to see my sister (www.ambercampbellthrows.blogspot.com) compete and I was turned away at the security checkpoint because I was carrying a digital SLR. This is from Cnet.com's CRAVE site.
If you're heading to Beijing (or are already there) for the Olympics, take note that the Beijing Organizing Committee has imposed bans on several items, one of which is "professional camera equipment." Unless you have official press credentials, we suggest you just bring your point-and-shoot to the games.
So what constitutes "professional camera equipment"? Are there any measurements or benchmarks to compare with? Although the definition wasn't detailed on the official Olympics Web site, some netizens are speculating that the ban refers to SLRs with big lenses that could block other spectators' views. But what about Fujifilm's FinePix S100fs, which is physically bigger than some entry-level dSLRs? Or the Olympus E-420 fitted with the 25mm pancake lens, a combination small enough to look like a bulky point-and-shoot?
If not properly stated, this vague description may trigger some arguments at the security checkpoint, and I don't think spectators will be happy to be rejected at the door just because of the equipment they are carrying. The best way to steer clear of all the trouble and get your seat? Leave your SLR at home.
