I am planning to rent a lens for next weekend to take some pre-bridal pictures of my sister, pictures of our twins, and family pictures (max 4-5 people hopefully). I will probably be shooting in the morning and evening, and maybe some candids during the day. I really want the 70-200 f/4L IS as I am considering purchasing it one day, but is f/4 enough for outdoor portraits in the morning and evening, and is it wide enough for what I want to shoot (I've never shot with a telephoto)? Would the 24-70 f/2.8L or 17-55 f/2.8 be a better choice? I do have a off-camera flash setup but I am limited to about 24', would the 70-200 be too long? Thanks!
70-200 f/4L IS
