My brother-in-law wants me to shoot his engagement photos because A)I have a camera and B)I'm free. I am by all means an amateur but he's seen what I've shot of my own family and decided that's good enough for him.
I don't necessarily have portrait quality lenses, so I plan to rent one for the session. I am shooting on a 7D body, so the 1.6 crop is my sticking point. My three choices and reasoning are:
85mm 1.8 - Best bokeh and sharp, but effectively a 136mm
50mm 1.4 - 2nd best bokeh, also sharp and only 80mm after crop.
24-70 2.8 - Most versatile but not as good of bokeh.
All input is appreciated.
