With the Eye-Fi X2 card, I could upload full res photos from my NEX 5 to my iPhone and then do what I wanted with them when you’re using the X2 card, you can connect the camera directly to your iPhone / iPad without having to use a Wifi router etc… You can also use the Eye-Fi app on your phone to upload your images to your computer / Flickr etc. But that’s no good, is it, I need a real life “this product works well for this purpose” scenario…
As such, I have been using the Eye-Fi Pro | X2 in my Sony NEX 5 around the house, on my weekly personal photo walks, it has been flawless – the app runs on my Mac and when I get back to my laptop, the images are there, ready for me to do what I’d like with them. I still do that with my 5DMKII, RAW images via CF reader into Lightroom – it works for me and I don’t have anything that needs to be filed or uploaded for any time critical purpose. When the company Eye-Fi started up back in 2005, I will admit that I was a little curious and wondered “ how could this device help me?” I was using dSLR cameras with CF cards and was content to photograph what I had to photograph and then remove my CF card, plug it into my computer and load the images into my file system. Everything is *right now* you want your images on line, you want your original files backed up, we want everything to happen quickly and easily with a minimum of fuss.
