    CCD's and Bad Pixels....
    I' ve read that CCD sensors have a limited lifespan of aproximately 10000 photos. Near that point "bad Pixels" beggin to appear. Is that true? And if so, does the video feature deteriorates the CCD's performance quicker?
    I have a Canon powershot A60 for about a year and i've already shot >3000 pics and videos. I consider to upgrade to powershot G6 but if the above are true, i wouldn't be intrested to lay that much mones to something that has an expire date.

    Surely you realise that just about everything has a use by date these days. Really, gone are the days of buying a fridge that will last you 100 years or a TV that will last you 40 years.

    This is a Society of the throw away and electronics these days are designed with a short life span for that reason to keep them as reduced in price as possible.

    I think you may have unrealistic expectations regarding the digital era.

    Just my views.

    Bad pixels are a fact of life with sensors. Before a camera is shipped, existing bad pixels are mapped out and not used by the sensor. With age, there is a small chance that a bad pixel or two will appear. If they bother you, you can send it back to the manufacturer for remapping.

    There is no time table for bad pixels, sensors do not "wear out" with use. A bad pixel could appear a day after purchase or never. My Canon G1, bought years ago when they first came out, still has no bad pixels.

    I would not worry about it.
