I'm a beginner with a D3400. I usually take photos of landscapes but cars are my passion. However a friend asked me to take portraits of her. Id prefer to just use what i have and not purchase a lense thats "ideal" for portraits. I plan to shoot her indoors and outdoors. The portraits will be for her linkedin page. The DX lenses i own are, kit, 35mm, micro 40mm, 55-200 and 70-300. Which lense would be the preferred option for portraits? I have a month or so before i need to do this, so i will continue researching here and youtube for additional tips. Any suggestions are appreciated!
