So I live in South Korea and I'm planning on making a trip to the DMZ (it's the De-Militarized Zone on the border between South Korea and North Korea). It's the world's most heavily protected border. You can do some tours there where they show you the tunnels North Koreans have dug into SK, the room where the cease-fire (but NOT peace treaty...the two countries continue to be at war, technically) was signed, etc. There are all sorts of rules as to what you can and can't do, take, wear, etc at the border. One of the rules is that no lens with a focal length of over 90mm is allowed in. Hurray for the M4/3's 2x crop factor!!! I'm going to take the OM-D with the O75.
