What is the Best Lens for Portrait Photography?

Sometimes it’s fun to write articles about a subject that doesn’t have a “one right answer.” Not only does it make me really think about the subject before I start writing but it’s also usually somewhat controversial and garners a lot of comments. So for this subject please put in your “two cents worth” either in the comments section here or on our Facebook page.
To begin with, I usually use my 70-200mm lens for portrait work. It works for me. It also works for a number of very successful portrait and wedding photographers I know. But there’s a catch, a number of reasons why that works for me and may not work for you. By sharing why it works for me and including reasons why it may not work in all situations you can modify my comments to fit your situation and approach.
1. The most widely held belief in answering this question is a lens in the range of 85mm to 135mm. I sure can’t argue with this as a good workable range. I’ll return to this later in the article.
2. For portrait work I use my Canon 5D Mark II Camera. That camera has a full-frame sensor so my 70-200mm lens is a true 70-200. If I were to use a camera with a cropped-frame sensor the lens would act as a longer lens. For example, if the crop ratio was 1.6, like on my Canon 7D Camera(Body Only), the apparent length of the lens would be 112-320mm. Useable but I would have to be farther away from the subject to capture the same image.
3. While I’m aware that some portrait photographers use a wide open f stop (f/1.4 to f/3.5 for example) so they get the bokeh they want in the background, I prefer to use f/8 to f/11. That way the entire subject is in focus. If I want fuzzy out-of-focus ears, which I generally don’t, I can do that in Photoshop. However, as you know, if it’s out of focus when I capture the image, it’s out of focus in the finished product. To keep the backdrop out of sharp focus I prefer to position the subject roughly 8 to 10 feet in front of the backdrop. Even with f/11 this is sufficient distance to get the effect I want.
4. The next self-imposed rule I like to follow is I don’t like to be up in the subject’s face. This usually isn’t an issue with a professional model, but with most clients, the greater the distance between them and the camera, the more comfortable and natural acting they are. Because of this, I like to position myself about 8 to 10 feet from the subject. Yes, I realize that this requires more than 20 feet of linear space to set up and not everyone has that much space. Well, my studio is located in my house and while the great room is more than 20 feet long I can’t see my wife allowing me to set up my studio there. What I do is park the car(s) in the driveway and set up the studio there. Works like a charm. Yes I have to set up and take down my studio equipment every time I use it, but I had that in mind when I purchased the equipment.
5. Another advantage I get by setting up 8 to 10 feet away is that the subject isn’t taking peeks at the computer screen and getting nervous because they don’t like what they’re seeing on the screen. Yes, I always shoot tethered to my laptop so that I can see what’s happening. A 15″ or 17″ computer screen sure beats chimping with the 3″ screen on the back of the camera.
6. When photographing portraits I tend to leave some “room” around the subject so I can crop the photo the way I want it to look. For the SOOC (straight out of camera) purists, I have to crop anyway. A full frame sensor has a length to width ratio of roughly 1:1.5, the same ratio as an 8×12 or 4×6. An 8×10 has a ratio of 1:1.25, an 11×14 ratio is 1:1.2727. So since I have to crop anyway, I might as well leave some working room. That said, I don’t want to crop so severely that I start getting noise in the final product. So if I want a really tight head shot, it’s a lot easier to zoom in a little with the 70-200 than it is to get right up into the subject’s face with a 50mm or a 35mm.
7. Now, back to the first statement regarding the 85mm – 135mm range for a “perfect” portrait lens. I went through metadata for a few hundred images and discovered that rarely did I have the lens zoomed to less than 80mm or more than 135mm. There were some at 70mm, mostly full body shots, and some at 200mm, mostly very tight head shots, but the overall results would seem to support the old belief of the best lens being around 85mm to 135mm.
8. I have a wonderful 100mm lens that is tack sharp. I could use it for portraits but I really like the versatility of the 70mm-200mm. I’ve heard some complaints about the weight of the big lens. The weight doesn’t bother me because I either have the camera on a tripod or I use my Black Rapid RS-7 camera strap and let the camera and lens hang next to my hip when I’m not actually shooting. You can see the review on the Black Rapid strap I wrote in December here
9. Keep in mind that if I were shooting with my 7D, a 50mm lens would approximate 85mm on a full frame sensor camera and 105mm would approximate 135mm. In this case, I might opt to use my 24mm-105mm lens and would get similar results.
The net result is that the best lens for portrait photography, like most things in photography, really depends on the camera you’re using and what you’re trying to accomplish. For me, it’s the 70-200mm.
One other thought that may be helpful. The absolute best lens for portrait photography is the highest quality professional grade lens in the focal length you want to use. If you think a kit lens works just fine, that’s okay. However, I suggest you rent a professional grade lens and try it out. Take a hundred or so portrait shots with it. Do the same with your kit lens of the same subject at the same time. Import them into photoshop and enlarge to 100%, 200% and 300% and see if they’re the same. If they are, congratulations, you have a really good kit lens.
