Here's a breakdown of the arguments for and against needing a 70-200mm lens for portrait photography:
Arguments FOR needing a 70-200mm lens for portraits:
* Compression: This is arguably the biggest benefit. The longer focal lengths of a 70-200mm lens create a compressed perspective. This means the background appears closer to the subject, making them stand out more and often creating a more flattering look by minimizing distortion.
* Subject Isolation & Background Blur (Bokeh): At f/2.8 (often the maximum aperture for 70-200mm lenses), you can achieve beautiful, creamy bokeh. The background melts away, further emphasizing the subject. Even at slightly smaller apertures, you can still achieve excellent subject isolation.
* Working Distance: The zoom range allows you to maintain a comfortable distance from your subject, which can be crucial for capturing natural, unposed expressions, especially with shy or self-conscious subjects. You can capture a range of shots – from headshots to full-body portraits – without physically moving too much.
* Versatility: While primarily used for portraits, the 70-200mm is also great for other genres like sports, wildlife, and events. It's a versatile lens that can be used in various situations.
* Flattering Perspective: Shooting from a distance often leads to a more flattering perspective, avoiding distortions like enlarged noses that can occur with wider lenses at close distances. The longer focal length tends to smooth out features.
Arguments AGAINST needing a 70-200mm lens for portraits:
* Cost: 70-200mm lenses, especially those with a fast aperture of f/2.8, are generally expensive. This can be a significant barrier for entry-level photographers.
* Weight & Size: These lenses are large and heavy, making them less convenient to carry around, especially for on-location shoots or travel.
* Limited Indoors: In smaller indoor spaces, the 70-200mm might be too long, making it difficult to compose shots.
* Alternative Options: There are other lenses that can produce excellent portraits, such as:
* 50mm: A classic portrait lens, especially the 50mm f/1.8 or f/1.4. They are affordable, lightweight, and great for environmental portraits.
* 85mm: Another popular choice. It offers good compression and bokeh without the size and weight of a 70-200mm. Many photographers prefer it as a dedicated portrait lens.
* 35mm: Excellent for environmental portraits where you want to show more of the surroundings and tell a story.
* Zoom Lenses like 24-70mm: Offers versatility and can be a good compromise, especially if you need to shoot in tighter spaces.
* Not Always Necessary for Style: The need for extreme background blur isn't universally desired. Some photographers prefer to include more of the environment in their portraits, making a wider lens a better choice.
Who REALLY "needs" a 70-200mm?
* Photographers who primarily shoot portraits: If portraits are your main genre, the 70-200mm can be a worthwhile investment, especially if you value compression and subject isolation.
* Photographers who shoot in uncontrolled environments: The zoom range allows you to adapt to different shooting situations without having to constantly change your position. This is especially helpful when working in crowded or unpredictable locations.
* Photographers who want to achieve a specific aesthetic: If you consistently strive for portraits with creamy bokeh and strong subject isolation, a 70-200mm f/2.8 is an excellent choice.
* Professionals: The 70-200mm is often considered a professional-grade lens due to its build quality, image quality, and versatility.
Who might NOT need a 70-200mm (or could get by with alternatives):
* Beginner photographers: Start with a more affordable and versatile prime lens like a 50mm or 35mm to learn the fundamentals of portrait photography.
* Photographers who shoot primarily indoors or in small studios: A shorter focal length lens might be more practical.
* Photographers who prefer environmental portraits: A wider lens like a 35mm or even a 24-70mm zoom might be a better fit.
* Photographers on a tight budget: There are many excellent and affordable portrait lenses available.
* Photographers who prioritize portability: The weight and size of a 70-200mm can be a burden.
In Conclusion:
The 70-200mm is a fantastic lens for portrait photography and offers many advantages. However, it's not an absolute necessity. Carefully consider your shooting style, budget, and the types of portraits you want to create before making a purchase. Experiment with other focal lengths and see what works best for you. You might find that an 85mm prime or a versatile 24-70mm zoom meets your needs just as well (or even better!).
