    Have a chance to pick up a Canon HF10 at a very attractive price ($400). I've been looking at the HF20 and HFS10 and am wondering if the HF10 is "good enough" given the price.

    HF 10 - 2.07 Megapixels (1920x1440) - 17 Mbps max
    HF 20 - 2.99 Megapixels (2304x1296) - 24 Mbps max (around $800)
    HFS10 - 6.01 Megapixels (3264x1840) - 24 Mbps max (around $1000)

    Isn't 1920x1080 considered "full HD" - it seems all three would be capable of that. Also, would the 17 vs. 24 Mbps be that noticeable? I'm after good vacation videos, band concerts, swim meets, etc... not a professional videographer.

    Opinions? Suggestions?

    Be careful, they list the cams as 8+ megapixels, but they top out much lower, at 1080p or so for video.

    As for the bitrate differences, it depends on what you're doing. If it's high motion you might notice compression, but for the casual user you'll be fine.

    the megapixel ratings are only for still images...

    all 3 of those cams record video at a max of 1920x1080.

    you probably won't see a difference in 17Mbps and 24Mbps.

    Early HDV cameras created 1080 (1920x1080) by extrapolation from smaller sensors. "Full HD" has come to mean that there's a 1:1 (or better) ratio of pixels from sensor to image.

    Differing opinion: 17 to 24 Mbps is not trivial. If everything you shoot is "spot on" you may never see the difference, but color correcting HDV footage is an iffy proposition at best, and working with 30-40% less data is going to make a difference.

    No HDV camera records at full HD. They scale not because of CCD sizes, but because of the HDV-2 encoding method of using non square pixels. HDV-1 uses 720p encoding and uses square pixels. But regardless, a straight hdmi output of a live feed from a HV30 is 1080p since it isn't being encoded to HDV.

    I think all the cameras the OP listed are AVCHD, not HDV, cameras BTW.

    and with the OP saying this is for vacation videos... I don't think the extra bits for color correction will be an issue.
