no.. you do not need one. save your pennies. If you have photoshop of some kind or access to: set your camera on a tripod and take several continuous pictures until you have the subject covered in whole. then you can photomerge them together with photoshop and crop them to the size you need... same effect as a wide angel but now its a panoramic of multi megapixel proportions.. 3 rulesl to follow to make good (pano) pictures: 1. Use manual exposure and pick one overall good exposure for all frames (use the same exposure in each frame). 2. Use manual focus on the subject and use the same focus in each frame. 3. Overlap the frames. When panning to the next (continuous) frame over lap the fram you're panning from by at least 1/4 of a frame. When you pan to the next frame.. you can go up, down, left or right or a combination of all, Photoshop will fix it later. You can see some of the examples of my (panoramic) pictures at:
