Had the Camera Connection Kit for iPad 2 with IOS 4.3 mienem without any problems in use (both with USB port on the camera as well as for various SD card). Unfortunately, Apple has built into the IOS 5.x a serious error, which means that when you import existing photos are recognized only randomly - 2/3 recognized, not 1/3. If you - like in my workflow - the card is not completely extinguished after each import, the kit is therefore completely useless. Error has been reported to Apple, according kanpp one years came the confirmation that this is a known bug - nothing more, even with iOS 6.x the error is not resolved. Anyone who is lucky enough to own a Ipad with old IOS, the CCK can buy, everyone should with IOS 5.x or 6.x IOS previously think through his workflow - because Apple prevents direct access from Apps to the CCK, there unfortunately no alternative apps that work around this shortcoming. Conclusion: Great hardware that is unusable because unfortunately grottiger Photo app in IOS and restrictive access policy on the part of Apple.
