I'm looking into purchasing a wireless remote from Amazon. I would really prefer to use them as I am also ordering a few more items at the same time. I'm looking at either the Adorama or Opteka wireless remotes, but as this is the first time in foraying into remotes, I'd like some advice. I have a 40D, and I'm wanting the option of opening the shutter for several minute long exposures, along with being able to take group shots with me in it!
