Haven't tried any fancy schmancy resolution charts or comparison tests but I know when I saw the results of our first shoot with the H1 I was impressed with the detail level.

This is a straight grab with no processing, shot in 25F mode.

Your shot illustrates what I consider to be the main difference between SD and HD: the ability to record texture.

you guys have to stop posting this kind of stuff or i may just have to buy one :)
