NEW SANDISK COMPACT MEMORY CARD BACKWARD COMPATIBLE IN COOLPIX3100??

On the same subject, a newbie question :
what is, generally speaking, the influence of the writing speed of a memory card, on the delay between two shots ? As I understand, informations must be written on the card in order for the camera to take another shot. The quantity of data depends of the format choosen, the level of compression, etc... For ex., on a Coolpix 5700, a RAW format weights around 7 MB, meaning that, with the 60x generation of card, it takes less than one second to write. And of course more with less recent cards. This delay can be significantly annoying. So I would like to know if it's worth buying speedier cards. Can someone of you knowledgeable gentlemen enlighten me ? Jean-Paul Bataille |

I believe the majority of current cameras, including the CP5700 are limited by the native buffer size and camera read-write speed, rather than card speed. Use of a card reader connected either by FireWire or USB2 is where the speed of the card shows up. The CP8700 takes advantage of the WriteAssist in Lexar cards, as do several other cameras. The difference between CP5700 and CP8700 write times on the same (40X) Lexar card is remarkable. I can't testify about buffer sizes, or other cards. -- Frank ess |
