: I just read about an SD card that transmits directly to any wi-fi : network that you don't have to log in to. I couldn't tell from the : description in the article in the paper whether the transmitter was : embedded in the card case somehow. I posted info on that on that December last year: Now, any camera that accepts an SD card can perform the same trick. The Eye-Fi Wireless SD Memory Card with 2 Gigabytes of storage embeds a chip-size transmitter that makes it possible for you to send your pictures to a computer and one of 17 photo-sharing sites through a wireless network. With the Eye-Fi Card ($99.99 B&H) <http://www.bhphotovideo.com/c/product/529317-REG/Eye_Fi_EYE_FI_2GB_Eye_Fi_Wireless_SD_Memory.html> : : I wonder about the USB prong, does it retract when you mount the card : in the camera? nope, it's within the physical size of the card - basically it's smaller than a standard SD : : Interesting that these things are only SD, however, since most pro : cameras are still coming with CF as the standard. professional is a funny term these days when it comes to cameras.. Sony's 24 Mp isn't considered a pro camera, but a 3mp Kodak once was. Pentax with the ability to use lenses spanning almost 50 years isn't considered pro, neither these days is a Canon F1N nor a Pentax LX - both modular warzone cameras.. AF is professional, AE is professional, bracketting is professional. but even so, as was said in the past, CF /SD card adapters are available quite cheaply allowing folks to use fast, cheap SD/MMC cards in CF media cameras. Or even wireless cards ;) Canon do make a CF wireless card but from memory it doesn't have the added 2Gb storage of the Eye-Fi karl
