Here's a breakdown of the pros and cons, and why it's so popular:
Why the 70-200mm is so popular for portrait photography:
* Compression: This is the lens's biggest selling point for portraits. Longer focal lengths compress perspective, making the background appear closer to the subject. This results in a more pleasing and less distorted facial structure, often considered more flattering. It can also create a shallow depth of field (bokeh) that effectively isolates the subject.
* Bokeh: While you can achieve bokeh with other lenses, the 70-200mm, especially with a wide aperture (f/2.8), is renowned for its creamy, dreamy, and beautiful background blur. This helps draw attention to the subject and creates a professional-looking image.
* Working Distance: The 70-200mm allows you to maintain a comfortable distance from your subject. This is especially beneficial when photographing children or people who might feel uncomfortable with a camera in their face. It also gives you room to pose and direct without being intrusive.
* Versatility: It's not *just* a portrait lens. The 70-200mm can be used for a variety of photography genres, including events, sports, wildlife (from a distance), and even some landscape details.
* Zoom Flexibility: The zoom range provides flexibility in framing. You can quickly switch between tighter headshots and wider waist-up shots without physically moving.
* Professional Look and Feel: Using a larger, more professional-looking lens can sometimes inspire confidence in your clients. It's a bit superficial, but the perception can matter.
Why you *might not* need a 70-200mm:
* Price: 70-200mm lenses, especially those with wide apertures (f/2.8), can be expensive. This can be a significant barrier to entry for aspiring portrait photographers.
* Size and Weight: They're large and heavy. Carrying one around all day can be tiring, especially on location.
* Space Requirements: They require a certain amount of distance between you and your subject. If you're shooting in a small studio or confined space, it might not be ideal.
* Alternatives Exist: There are other lenses that can produce excellent portraits, often at a lower price point:
* 85mm f/1.8 or f/1.4: Considered a classic portrait lens, providing excellent image quality, shallow depth of field, and a more manageable size and weight.
* 50mm f/1.8 or f/1.4: Versatile and affordable, good for environmental portraits and can still achieve a decent amount of bokeh.
* 35mm f/1.4 or f/1.8: Excellent for environmental portraits, telling a story, and showing the subject in context.
* Skill Over Gear: Ultimately, a skilled photographer can create beautiful portraits with almost any lens. Understanding lighting, posing, composition, and post-processing is far more important than owning a specific piece of equipment.
In conclusion:
The 70-200mm lens is a valuable asset for many portrait photographers, offering unique advantages in terms of compression, bokeh, working distance, and versatility. However, it's not an absolute necessity. If you're on a budget, starting with an 85mm or even a 50mm lens is a perfectly viable option.
Before investing in a 70-200mm, consider:
* Your budget: Can you afford a high-quality version?
* Your shooting style: Do you frequently shoot portraits from a distance?
* Your typical shooting environment: Do you have the space to use it effectively?
* Your specific needs: What kind of look are you trying to achieve in your portraits?
* Rent before you buy: Rent a 70-200mm for a weekend and see if it fits your workflow and creative vision.
Ultimately, the best lens for *you* is the one that helps you achieve your artistic goals and meets your practical needs. Don't feel pressured to buy a 70-200mm just because it's popular. Experiment, find what works best for your style, and prioritize developing your skills as a photographer.
