Pentax today brought out a replacement for its long-serving X70. As an ultrazoom, the X90 already carries a 26X lens (26-676mm equivalent) but uses an "intelligent zoom" in software to reach 162.5X (4,225mm). Like most of these features, Pentax claims to avoid most of the typical degradation in image quality but hasn't said whether any obvious sacrifices are needed to reach the record-setting distance.
