I just bought this http://cgi.ebay.com …geName=ADME:X:RTQ:US:1123
today and I just realized that it is not suited for a Canon Rebel XS (1000D). I emailed the seller and he replied with, "If you want to use this item in a Canon 1000D in wireless remote control function, you need to buy a shutter release cable for Canon 1000D. "
So my question, being a beginner, how will this affect the functionality of this? I'm not sure I even really understand what the wireless remote is for other than taking pictures of yourself or long exposures, and stuff.
Any help would be great! Thank you!
