Having recently bought a 12mp G1X with Wi-Fi, its a klutz. Canon should leave off Wi-Fi until they can get it right.
Canon Wi-Fi requires that the Canon site be up and working just to do a direct transfer to your computer. Their iMAGE site has been repeatedly down, last weekend until Thursday I was not able to use my Wi-?Fi to transfer images. It took me until Friday to get it to work again, I had to re-register with the site because they changed the login, then erase all my wifi settings from the camera, then reload the 230 MB files and go thru the setup process again, which is slow and goofy. Now its working again, but for how long??
In the meantime, I bought a eye-Fi card and put it in my 5D3. Easy setup, and it works great. Then I popped it in my 1GX just to see what happens, and it works with no setup to card or camera.
I'd much prefer it to the Goofy Canon WiFi which is unreliable.
Gotta say I agree. I have the 6D, I'm an IT guy. I have a lot of experience with lots of WiFi. The 6D has pretty bare minimum functionality and it's difficult to work with on the camera. I guess they decide on some features last minute from the marketing dept and then barely even test/use them. That's what it feels like sometimes, anyway.
