The best Nikon D lenses for portrait photography are the Nikon AF-S NIKKOR 85mm f/1.8G, Nikon AF-S NIKKOR 50mm f/1.8G, and Nikon AF-S NIKKOR 105mm f/1.4E ED. These lenses are known for their sharpness, beautiful bokeh, and ability to capture stunning portraits with great detail and clarity.
Yes
If the camera is for professional purposes or you are skilled on single lens reflex cameras, I recommend the Nikon D 200 or similar. I am a professional photographer and I use Nikon D 200, Olympus E-3 and Fuji S-3 Pro. Believe me, Nikon is the best choice.
