I will
have to do a patent search and see what patents Pentax has filed, but I would think some type of anti shake is overdue. Apparently, Pentax has indeed recently filed such a patent application - this was discussed in the dpreview forum a few weeks ago. What you may also find interesting is another rumor that was circulating on dpreview a couple of months ago: that Pentax had discontinued many or even most of their basic full-frame 35mm lenses and were supposedly going to concentrate on the digital series. If true, this would suggest that any higher-end digital cameras to come would not be full-frame but still APS - Pentax is also apparently committed to medium format as the next step up. --------------- Marc Sabatella The Outside Shore Music, art, & educational materials: http://www.outsideshore.com/ |

Makes me wonder if the K-M sensor-based IS solution is a license of
Pentax' patent. Canon's eye-controlled AF was licensed from Pentax. And I'm certain Pentax licenses from the others as well. Seems to be the Japanese camera mfr. method. Collin KC8TKA |

Almost every manufacturer has licensed the TTL automatic flash control from Minolta. |

IBM made more from licensing technology developed at the Watson Lab than they ever did selling IBM PCs. Most hard drive technology in the world depends on IBM patented technology, including those micro drives that fit in a CF card. |
