A very useful non-Olympus accessory is the OLYCAP, a spring- loaded slip-on lens cap that sells for just $9.50. You'll never have to deal with a "dangling" or lost lens cap again!

Also included is the RM-2 remote control, which is handy for tripping the shutter when you have the camera on a tripod for self-portraits or Macro photography.
