Here's a breakdown of the pros and cons to help you decide:
Why a 70-200mm Lens is GREAT for Portrait Photography:
* Compression: The telephoto range of the 70-200mm compresses the perspective, which is often flattering for portraits. It minimizes distortion, especially on facial features, leading to a more natural and pleasing look. This effect makes subjects appear less stretched and more proportionate.
* Background Blur (Bokeh): Especially a 70-200mm f/2.8, it excels at creating beautiful, creamy background blur (bokeh). This helps isolate your subject and eliminate distracting backgrounds. The long focal length combined with a wide aperture creates a shallow depth of field, drawing the viewer's eye to the subject.
* Working Distance: Allows you to shoot portraits from a comfortable distance, making your subject feel less self-conscious and more relaxed. You don't need to be right in their face, which can lead to more natural expressions.
* Versatility: While primarily used for portraits, a 70-200mm can also be used for other types of photography, such as sports, wildlife, and events. This makes it a more versatile investment than a lens designed solely for portraits.
* Sharpness: Generally, 70-200mm lenses are known for their excellent sharpness, contributing to highly detailed and professional-looking portraits.
* Image Stabilization (IS/VR): Many 70-200mm lenses come with image stabilization, which helps to reduce camera shake and allows you to shoot at slower shutter speeds, particularly useful in low light.
* Professional Look: Using a 70-200mm often gives clients the perception that you are a serious, professional photographer, potentially influencing their confidence in your services.
Why You Might NOT Need a 70-200mm Lens for Portrait Photography:
* Price: 70-200mm lenses, especially the f/2.8 versions, are expensive. They are a significant investment.
* Size and Weight: These lenses are large and heavy, which can be cumbersome to carry around for extended periods. This can be a problem for on-location shoots where you're moving frequently.
* Indoor Shooting: The long focal length can be limiting in smaller indoor spaces. You might not have enough room to step back far enough to frame your subject properly.
* Overlap with Other Lenses: If you already own a good prime lens like an 85mm or 50mm, the benefits of a 70-200mm might not be as significant, especially if you primarily shoot in controlled environments.
* Style Considerations: If you prefer wider, environmental portraits that show more of the background and context, a 70-200mm might not be the ideal choice. You might prefer a 35mm or 50mm lens.
* Alternatives:
* 85mm Lens: A popular and more affordable prime lens that offers excellent image quality and background blur for portraits. It's often considered the "portrait prime."
* 50mm Lens: A versatile and affordable option that can be used for portraits, especially when you want to include more of the environment.
* Zoom Lenses (Shorter Range): Lenses like a 24-70mm can be a good compromise if you need versatility for other types of photography and still want to shoot portraits.
* 70-300mm Lens: A less expensive alternative that offers a similar focal range, but may not have the same wide aperture or image quality as a 70-200mm.
Here's a more detailed breakdown to help you decide:
Consider Getting a 70-200mm If:
* You prioritize background blur and subject isolation.
* You frequently shoot outdoors or in large spaces.
* You want to maintain a comfortable distance from your subject.
* You're willing to invest in a high-quality lens.
* You need a versatile lens for other types of photography.
* You want that "professional" look and feel.
Consider a Different Option If:
* You're on a tight budget.
* You primarily shoot indoors in small spaces.
* You prefer wider, environmental portraits.
* You value portability and lightweight gear.
* You already own a high-quality portrait prime lens (like an 85mm).
In conclusion:
The 70-200mm lens is undoubtedly a fantastic tool for portrait photography, but it's not a necessity. Carefully consider your budget, shooting style, environment, and existing gear before making a decision. Renting a 70-200mm for a weekend is a great way to see if it fits your needs before committing to a purchase. Ultimately, the best lens is the one that helps you achieve your creative vision and deliver the results you and your clients desire.
