I'd have to check to see if it will take a standard wired trigger - However I would suggest that you could use the timer function. I know this camera has one, can't quite remember if it has a 2 second or 10 second timer but it has one of those. Set the drive to this and press the shutter and let it take - That way by the time the shutter opens you won't be touching it therefore you wont introduce any camera shake.
I have used that mode on most of my cameras over the time when I don't have my remote shutter release with me.
