Hi Tim, Yes, but they still need to stitch. Circular fisheye lenses typically give a complete 180 degree field of view within the film frame, but there are legendary Nikon lenses which give 220 degree circular FOV! Even parabolic mirror lenses, which give 360 degree horizontal FOV, have limitations in vertical FOV, requiring stitching to produce a spherical 360x180 view. The latest trend is to use lenses with lesser FOV, but to stitch overlapping frame shot using a "spherical" camera bracket. It is thereby possible to construct a 360x180 view WITHOUT using a fisheye lens. So, while the D30 comes with software to stitch photo mosaics, the technique is not so simple, and there are many traps. But isn't that what photography is all about :-) Cheers Julian Loke * **** ******* *********************************************************** * For list instructions, including unsubscribe, see: * http://www.a1.nl/phomepag/markerink/eos_list.htm ***********************************************************
