Originally posted by Jun Park I am also hesitant to put too many pictures on a single card because as the primary event photograper, you're not allowed to tell the client "My card died. Sorry." So I only use 2 GB cards, though I am considering using 4 GB cards but keeping the number of pictures to under 200 or so per card.
... I'm will to pay for fast cards because you can't change out to a new card until the camera is finished writing to the current card. And as you may know, seconds can matter in event photography!
This is a difficult issue, I think.
With the K20D's huge files, it seems that bigger cards are necessary. And of course I get far fewer raw files on an 8 GB card using the K20D than I'd get using the K10D. Since the files are about twice as big as those from the K10D, it's as if I've jumped from a 2 GB card to a 4 GB in terms of the
number of photos that each card can hold.
Changing cards is a pain and a distraction, and when I use small cards it seems I always have to change at awkward moments. So the best policy is to have cards that are much bigger than I need, and to change when it's convenient. For the wedding I shot a couple of weeks ago, I did the shots at the salon on a 2 GB card. For the church ceremony, I used an 8 GB card in the K20D and a 2 GB card in the K10D. Took those cards out afterwards and replaced them with fresh 8 GB and 2 GB cards, for the K20D and K10D respectively, for the reception. That's a total of (8 * 2) + (2 * 3) = 22 GB of storage. Now I didn't shoot 22 GB of photos, but I also didn't have to worry about changing cards suddenly.
I doubt that new 8 GB cards are more likely to fail than older 2 GB cards. Of course, if one did fail, it would have more photos on it than a 2 GB card.
But on the other hand, the more used cards I have to keep track of during the event, the greater the odds that I'll either lose one or overwrite it accidentally. Of course I have careful procedures that designed to prevent me from doing this. I'm just saying that there is more than one way to lose photos. To be honest, I think the odds of the card failing
irrecoverably are smaller than the odds of me simply LOSING a card.
Shooting with 2 cameras means that I'm getting some shots on to different cards. It would be nice if the K20D could write to two different cards simultaneously, but I wouldn't pay $500 more for it.
Ultimately, cards are a lot like film cannisters. You still have to be careful and hope that something bad doesn't happen between the shot and the darkroom.
