Lew,
The lens went wrong! Anytime you add something to a lens to make it do something that it's not designed to do you make it optically flawed. This is a common problem with Digital cameras that have fixed lenses. When you want to go wide angle you need to attach somthing to the font of the lens, this makes the lens worse.
Digital SLR's do not have this problem because if you want to use a wide angel lens you simpely remove the lens that is on it and attach a wide angle one.

You can still take a good family photo, you will just have to take off the attachment and move back to get every one in. (So with that camera, you may have to go outside) The best range for portraits to not get distortion is between 100-150mm (35mm equiv) 135 is concidered nominal :)

To large extent it's math. The person in the middle is X distance from the lense. The sides are X + from the lense. The focus on an attachment is from the centre of the lense. Because the sides of the attachment bevel out, they are out of focus. You can only use attachments like this for selective focusing. Great tools if used for the right job. As stated earlier, you will have to move back to include everyone.
