By using the Eye-Fi X2 SD card and mobile app you can wirelessly transfer photos from your DSLR to your phone and post them on Instagram just moments after you take them. The Eye-fi card is also useful for geotagging photos and uploading to photo sharing sites like Flickr and Facebook.
If you use a camera that only takes CF cards like our Canon 5d mkii then you can use one of these CF to SD adapters.
