As promised in another thread, I am reporting back on my attempt to make my four DSLRs WiFi Capable. My cameras range in age from 2002 to 2014 (2 X Canon, 2 X Pentax) and none of them have built-in WiFi. The Pentax cameras use SD cards and the Canons use CF cards. The first thing I did was to purchase a 16GB Toshiba FlashAir SD card. This card has built-in antenna and a WiFi chip. I installed the Toshiba FlashAir app on my Samsung S7 mobile phone and a similar program on my desktop. Transferring RAW and Jpeg images from the SD card in my Pentax cameras was both fast and simple. The next step was the purchase of an SD to CF adapter. Initially I was led to think that those adapters were only available as a Type II card but that is untrue and I got a Type I version. It arrived today and I checked it out in my EOS-1Ds and my 20D. First I checked that it worked with a normal SD card and then I put the FlashAir card in and that worked as well. So, I considered that the exercise was a success. Any camera that uses CF cards can be made WiFi capable with the above combination. And any camera that used SD cards can also be made WiFi capable with a WiFi SD card. There are brands other than Toshiba available. That just happens to be the one I chose after reading some positive reviews. I hope the above helps anyone who wants to use WiFi to transfer images to either mobile phone, tablet, laptop, desktop or any other WiFi device.
