I bet as HDTV becomes the norm & the standard TV screen is 16:9, there will be WAY MORE H format digicams because digital photos look pretty nice on a HDTV ( My 34" SONY HDTV does digital photo display and slide shows via a memory stick slot). JCO

APS-H is the HDTV format on APS thats ~ 16x30, the other APS format is panoramic which is 10x30mm. As far as I now there aren't any Digital cameras that have a Panoramic sensor. I doubt that there are any that have an APS-H sized sensor. BTW all of these are only approximated by digital manufactures, the ratios of the sensors are not quite the same as APS or 35mm and the sensor size is a bit smaller than APS-C as well, (though not much smaller), Pentax for example is actually 23.5x15.7.

During a war you get to drive tanks through the sides of buildings and shoot foreigners - two things that are usually frowned on during peacetime. --P.J. O'Rourke
