Connecting a Canon S100 camera to a Nexus 7 tablet via USB for direct file transfer is not feasible due to the differing USB port types (mini USB on the camera and micro USB on the tablet). However, an alternative solution is available through Eye-Fi cards, which enable automatic wireless photo transfers from the camera to the tablet using built-in Wi-Fi. This method requires downloading an Android app for the tablet and is compatible with the Canon S100.For those seeking a wired solution, an OTG (On-The-Go) adapter may work, allowing the tablet to read files from the camera, although this may require additional software and possibly rooting the device. There are discussions about the potential for DIY solutions by splicing cables, as mini and micro USB ports are electrically compatible. While Eye-Fi is the primary option mentioned, there are considerations regarding speed and efficiency, with mentions of upcoming products like Gnarbox aimed at enhancing the editing and transfer process.
