    I recently bought a new Canon s410. The Flash memory card is very
    small- 32 I think. Obviously I need to upgrade. I was thinking to a
    512. Is there something I should look for in a flash memory card? Any
    specifics I need? And, how many pics should a 512 give me?

  2. It depends on how large the file will be-mine Kodal Cx 7300 with 3.2
    megapixels needs 750 kB for each picture, in best quality, and my 128 MB
    card can take up to 160.Your camera's instruction booklet certainly says
    something relevant.I bought a lexar card (33 euro) and works fine up till

    A 4mp camera will usually produce JPEG format picture files of between
    ..5 and 2mp in size depending on compression and subject matter. I
    believe that a 256mb card would be a good size. I all probability a
    512mb card would only get filled up on a particularly long, and/or
    scenic, vacation. I filled one 128 meg card and a 256 meg card on a 7
    day Alaskan Cruise (470 pictures). You should get between 400 and 500
    pictures on a 512 meg card.

  4. I have a S410, and always shoot at the Superfine Large setting (maximum
    quality available). At that setting, the camera estimates 123 pictures
    will fit on a 256 MB card. So a 512 MB card will give you nearly 250
    still images. (Actual numbers may be larger or smaller depending on
    image complexity).

    You can get more images by selecting a lower resolution or lower
    quality, but I don't recommend that. CF memory is cheap. Video eats
    space rapidly, so if you want to shoot movies you need to allow for

    Thanks for the great replies. I have decided on a 256 MB. Does it
    matter what kind, style, brand? Or anything else to watch out for?

  6. The FIRST thing I look for in a flash card is getting the most megabytes
    for the least megabucks. And I really don't worry too much about how
    "fast" the card is. Speed makes a difference, if you're shooting lots
    of shots, very rapidly, like with sports or action photography, since
    fast card writes are needed to prevent the camera's internal buffer
    from maxing out and "freezing" the camera. But for average picture
    taking, most any card is fast enough.

    A 512MB card, based on Canon's own file size specs for the S410, will
    hold about 225 maximum resolution images at the "best quality" JPEG
    compression. I suspect this is a conservative estimate, and such a
    card will hold more. Is that enough images per card for you?

    Personally, for safety, I'd rather use several, smaller capacity cards
    distributing the day's shoot over them, even if I don't fill each card.
    My rule of thumb for the capacity of each is around 100 images of the
    largest file size I MIGHT use for a particular camera. For example,
    with my Canon D30, a 3.3 MP camera, I use 256MB cards, since they will
    hold 90+ RAW format images -- pretty close to that 100 criteria -- or
    around 200 "best quality" JPEGs. I have 6 cards. This is more than
    enough storage, except for the most extreme day's shooting.

    FWIW, I think the 100 images criteria comes from my long ago and far far
    away, b&w film, one camera, one lens amateur days, when I had one 36
    exposure roll in the camera, and two taped to the camera strap, a
    potential maximum of 108 shots.

  7. In my experience, for the most part, no. Just buy from reputable
    retailers/discounters so that if you get a bad one, you can exchange it
    for a good one.

    Is there something about "speed rating" that I need to worry about?
