Reasons Why the 70-200mm is Popular for Portrait Photography:
* Compression: The longer focal length (especially around 135mm and above) provides excellent subject compression. This means that the background appears closer to the subject, creating a more flattering and often more visually appealing image. It also helps minimize the size of features like noses and ears.
* Background Blur (Bokeh): A 70-200mm, especially if it's a f/2.8 version, can create beautiful background blur. This helps isolate the subject and draw the viewer's eye to them. Even an f/4 version can produce pleasing bokeh.
* Working Distance: Allows you to stand further away from your subject. This can be beneficial for several reasons:
* Comfort: Some subjects feel more comfortable and relaxed when you're not right in their face.
* Natural Expressions: Gives you a better chance of capturing genuine expressions because they're less aware of the camera's immediate presence.
* Environmental Portraits: Allows you to incorporate more of the environment without sacrificing background blur.
* Versatility: The zoom range allows you to quickly adjust your framing from headshots to full-body shots without physically moving. This is particularly useful in fast-paced shooting situations.
* Image Quality: Generally, 70-200mm lenses are built to a high standard, offering excellent sharpness, contrast, and color rendition. Many pro photographers swear by them for their optical quality.
However, It's Not *Always* Necessary:
* Other Lenses Can Work Great: There are many other excellent portrait lenses:
* 50mm: Versatile and affordable. A "nifty fifty" is a classic choice, especially for tighter shots.
* 85mm: Considered by many to be the ideal focal length for portraits. Provides excellent compression and bokeh.
* 35mm: Great for environmental portraits and wider shots, especially if you want to tell a story or show the context.
* Space Constraints: If you're shooting in a small studio or tight location, a 70-200mm might be too long. You might not be able to stand far enough back to get the shot you want.
* Budget: 70-200mm lenses, especially the f/2.8 versions, are often expensive. You can get excellent results with cheaper prime lenses.
* Shooting Style: Your preferred shooting style might not require the compression or bokeh of a 70-200mm. If you prefer wider environmental portraits, a 35mm or 50mm might be a better fit.
* Crop Sensor Considerations: On a crop sensor camera, the 70-200mm effectively becomes a 105-300mm (or similar), making it even longer and potentially less versatile in tighter spaces.
Consider These Questions Before Buying:
* What kind of portraits do you shoot? Headshots, full-body, environmental, etc.?
* Where do you shoot? Studio, on location, indoors, outdoors?
* What's your budget?
* What lenses do you already have?
* Can you rent one to try it out? This is highly recommended!
In Conclusion:
A 70-200mm is a fantastic lens for portrait photography and offers many advantages. However, it's not a magic bullet. Think about your specific needs, shooting style, and budget before investing. Experiment with other lenses to see what works best for you. You might find that you prefer a different focal length altogether. The best lens is the one that helps you create the images you envision.
