Skatol said:I agree that built in WiFi would be nice for this. Have you tried the CamRanger? This works works very well and adds several features that are not native to the 5DIII.
Yes, it is a relatively expensive accessory but solves the issue you state, and does it well.
I have looked at it but ended up not buying it because I saw the 6D beginning to march in this direction and figured the next would definitely have it. I am not sure if the 5Ds has it as well now but I'm definitely expecting it for the 5D MKIV and 1DX MKII and will be disappointed if they omit it.
