You'll get a better camera with the Widelux. FWIW, the lens quality is really good with them, also...I used my F7 to make images I printed myself for an exhibition; got nice prints 20" wide from the 35mm neg.
You'll have to watch out for 'banding', caused by the gears moving the lens at an uneven rate as it swings from side to side. It's the most common problem with these cameras. If you can find one in decent shape it's very much worth the cost.
