It is advertised as "the first of a new series": http://www.pentax.jp/english/news/2010/201007.html

The two Pentax 645 zooms I had were dreadful, though. Nice useful ranges, but the clarity just wasn't there, and using those zooms on this new digital body might disappoint. Hell, they *will* disappoint! Anyway, I don't have it any more, and have no plans to purchase any gear beyond the Canon 70-200 f4 L IS next week. For me, the 5D II is all I need, and changing gear will not improve my photos, that's for certain... |
