>>3476799if you're after pics like #1 then for sure go with the 85mm. It's shallow depth of field will create lovely portraits
Speedlight do indeed look like pic #2 if on camera and not diffused. If its not your thing then by all means go 85mm with a 6D. you will be very Happy with this combo. I have a 6D myself and i Love it. Pictures like #1 are very easy to accomplish
cheers
