I tried the camera lenses on the PJ last night and they work, but not very well. First, the position of the lens on the 725/730 is not conducive to mounting another lens. The zoom worked pretty well, but was tough to get close enough to the other lens to focus properly. I could see it being useful on a PJ with an exposed or more accessible lens to increase throw distance. The wide angle worked as well, but curved the top of the image. Again, maybe if I could get it closer to the other lens, the distortion might be eliminated. I may have to pull out the old S1+ and see how they work with a more accessible lens.
