aloha,
ordered one...
Figured I'd want something other than manual release for the bulb function as I'll be shooting in 0C weather, and I'm sure there would be some "camera shake" as i freeze my butt off!
If you are shooting in cold weather, take a cable release as well--the IR remote battery can get drained. I bought a cheap $6 release and after a little trimming, it fits the camera nicely.
