I have a couple of questions for you.

What is the return policy of the store?

Why not buy it, shoot some footage and see for yourself? If it does not do what you want return it.

Just a thought.

I don't know anything specifically about this camera, but I know how I would shoot for widescreen on a prosumer video camera...

Just frame your shots in camera so that you can apply a widescreen mask in post. Very simple. To make it easier to get an idea of what the shot will look like, run a video signal from the camera to a separate montior, then take some 2" masking tape and tape off the top and bottom of the monitor screen to approximate a 16:9 frameline. Then compose your shot into that frame. Of coure when you actually shoot it, you're going to get more information on the top and bottom of the frame than you need, but it doesn't matter because you're going to mask that off in post anyway. You can even let your boom mic (if using) drop into that part of the frame to get closer to the subject for better sound, knowing that it will be masked in post.

how do you mask it off in post?

To mask the frame in post, simply apply your "black bars" to the top and bottom of the frame. I'm not an editor myself and I don't know the programs, but I do know that it's possible to select an aspect ratio and apply it to the image. Obviously this is a cheat, and you're not actually gaining "true widescreen" as you would with a camera gate that was set up for widescreen, but at least you're not compressing or squeezing an image to fake like it's widescreen.

Like I say I don't know the process in the editing software to do it, but it's definitely doable and fairly easy too I think.
