Lenses for Portrait Photography

Portrait Lenses

A good 'Portrait lens' should be able to separate the person being photographed from the background and feature him/her in a pleasing perspective.

Imagine that you’re taking a photograph of a beautiful model out-doors, near a forest, under the shade of some massive evergreen trees with gigantic ferns in the background (don't look to the left, picture this in your mind). You’d want to get the model in sharp focus but if the ferns are also in focus, they’d just add clutter to the photograph. In this case, a telephoto lens set at a nice, wide aperture will give you a shallow depth of field, separating the model and the background. If you’re just using natural light with some reflectors, the added advantage of having a fast lens is that you’ll be able to shoot at faster shutter speeds!

The best range of focal lengths
Most photographers use a zoom lens in the 85-135mm range for most of their portrait photography. Some of the faster lenses in this range of focal lengths come with apertures as wide as f/2.8 and f/1.8. Canon’s EF 70-200mm f/2.8L IS lens is one such lens.

You’ll also want a lens that enables you to stand a reasonable distance away from the subject. Long focal lengths help with that… Staying away from the subject and taking portraits with a 70mm or 135mm lens has two major benefits.

1. The first is that it gives the sitter’s face a pleasing perspective. Noses are not enlarged and sticking into the camera while ears disappear into the distance; instead they are nicely proportionate to each other.
2. The second is that you will be able to give the model or sitter some space instead of intruding into their personal space. This always makes the sitter more comfortable, making for a more productive shoot.

At the same time, you don’t want to be too far away from the sitter, making it difficult to communicate… Also, you may not have all that much space! Taking a full length portrait of a 5’ 10” model with a 200mm lens would require you to stand about 30-40 feet away! So, extremely long focal length lenses are generally given a miss for this category unless you’re doing some really tight close-ups, in which case it would generally be cheaper to take a couple of steps forwards!

Alternate Focal lengths

The 70-200mm lens we talked about earlier is great if you’re doing half-length or close up shots, but if you’re taking full length, or group portraits, you may want to add a wider zoom to your repertoire of lenses to give your photographs some variety. A wide-to-medium-telephoto lens is usually good for this usage. I use the Canon EF 24-70mm f/2.8L lens but have to keep reminding myself to stay at the telephoto end of the lens. A good way to remind yourself not to go wide is to set a marker at a safe distance away from the model and to remain behind it at all times. This will ensure that you don't distort the sitter's features beyond their most pleasing proportions.

Of course, there are always exceptions to the rule and sometimes a portrait taken with a wide-angle lens could emphasise a certain quirky aspect of your sitter’s personality, so remember, there is always room for a couple of pictures taken with non-standard focal lengths and angles…

Portraits with a Prime Lens
Some photographers prefer to use 'Prime lenses' (also called block lenses) for portraiture because of the increased sharpness over zoom lenses. The Canon EF 85mm f/1.2L is one of the major candidates for this as many photographers feel that the perspective and bokeh. Many photographers also like using 105mm and 135mm prime lenses for their portrait photography. However, using a prime lens means that you have to keep 'shunting' forwards and backwards to get your framing right.
