Just what you wanted to hear, huh? ;-)
There might be a TC that you could hook up on there. B&H doesn't show one.
Since they don't show one, it doesn't mean there isn't one, but it could mean you will lose auto focus if you use one.
Have the local camera shop prove it to you.
Having said all of that, I'd probably not do that with that lens. It's a F/4-5.6, which means it's kinda slow at 5.6 (less light entering the lens). Adding a TC will reduce the light even more, 6.5 or worse.
What all this means to you is:
1. you've increased your focal length, so you need more shutter speed to prevent blurry photos.
2. You've decreased the amount of light you're using, so you CAN'T have the shutter speed that you need.
3, So then you increase the ISO to something ridicules and get grainy looking photos.
I'd forget the whole idea if I was you.
