I bought the card to the studio quite quickly be able to judge the shot images on the iPad, which is hardly possible on the camera previews. Therefore, the previews of the images should as quickly as possible on the iPad come to allow there to evaluate the picture. For this I set the camera to RAW + JPEG 2M. The card I operate in direct mode. To ensure that only the JPEGs are moved via WLAN to the iPad and the RAW images remain first of all on the map. After the write operation of the camera is complete, it takes 3-4 seconds to continue the image on the iPad has arrived. For me, a perfectly acceptable time. If you shoot series stores the card out the images and then begins transmitting. When a burst of images transmitted takes the transmission depending JPEGs only 1 second. If you compare the JPEGs to a larger size, the transmission time increases logically. A 16M JPEG lasts in the neighborhood about 7 seconds at 12 meters about 14 seconds.
The range of the card is of course limited, as the suggests. If you have the iPad lying next to the camera to get to the described 3-4 seconds transmission time. This works even at about 5 meters. Then the speed is then already. At 12 meters I had made 6 seconds transmission time. Through a closed door through a transfer in direct mode was no longer possible (old, wooden door and brick walls).
Once the connection is torn down and you return to the iPad back once you have a "blank screen," shoot, so that synchronization is resumed.
One more tip for the setup. Once the setup statement [...] very carefully work through from top to bottom. Then everything will be fine.
On the 4GB card I get almost 200 RAW images with JPEG preview. Then you have the map then on the iPad drain (or take another card). The pictures are of course double on the iPad and you have to watch when imported into Llightroom / Aperture that you caught the right images and previews can be on the iPad.
Who does not need all the other bells and whistles of the Eye-Fi card gets a great bridge for preview images, for a very reasonable price with this 4GB version of SanDisk.
