* Your style of photography: Are you shooting tight headshots, environmental portraits, full-length portraits, candid portraits, or a mix?
* Your shooting environment: Studio, outdoor, events, or a combination?
* Your budget: A 70-200mm is generally a significant investment.
* Your existing gear: Do you already have other lenses that might cover some of the same ground?
Here's a breakdown of the pros and cons of a 70-200mm for portrait photography, to help you decide if it's a "need" or a "want":
Arguments FOR needing a 70-200mm:
* Compression: This is perhaps the biggest draw. The longer focal lengths (135mm-200mm) offer excellent compression, which can be very flattering. It minimizes perspective distortion, making facial features appear more balanced and natural. The background appears closer to the subject, which can be useful for filling the frame and simplifying compositions.
* Bokeh (Background Blur): 70-200mm lenses, especially those with wide apertures (f/2.8 is common), create beautiful, creamy bokeh that separates the subject from the background, drawing the viewer's eye to the person. This is especially useful in busy or distracting environments.
* Working Distance: The zoom range allows you to maintain a comfortable distance from your subject, which can be crucial for candid shots, shy subjects, or when you want to avoid intruding on their personal space. It's also great for event photography where you can't always get close.
* Versatility: While known for portraits, a 70-200mm is also useful for other types of photography, such as sports, wildlife, and even landscape details.
* Professional Image: Let's be honest, a 70-200mm, especially the f/2.8 version, looks impressive and can project an image of professionalism to clients.
Arguments AGAINST needing a 70-200mm:
* Cost: A high-quality 70-200mm lens can be expensive, representing a significant investment.
* Size and Weight: These lenses are large and heavy, which can be tiring to carry around all day. They might require a larger camera bag or a dedicated lens case.
* May not be ideal for tight spaces/studio: In a small studio or indoor environment, a 70-200mm can be too long. You might find yourself backing up against walls to get the shot.
* Alternatives Exist: Other lenses can achieve similar results, sometimes at a lower cost and with less bulk.
* 85mm prime: A popular portrait lens that offers excellent image quality, beautiful bokeh, and a relatively compact size. Often more affordable than a 70-200mm.
* 135mm prime: Provides excellent compression and background blur, and is often sharper than a 70-200mm.
* 50mm lens: Versatile and affordable. Can be used for portraits, especially in environmental settings, but doesn't offer the same compression or background blur as longer lenses.
* Learning Curve: While generally easy to use, mastering the 70-200mm, especially at wider apertures, requires practice to consistently nail focus, particularly on moving subjects.
So, DO YOU NEED ONE? Consider these questions:
* What is your primary portrait style? If you mainly shoot tight headshots in a studio, an 85mm or even a 50mm might be a better choice. If you shoot full-length portraits outdoors, the 70-200mm can be invaluable.
* What is your budget? If you're just starting out, a less expensive prime lens (like an 85mm f/1.8 or 50mm f/1.8) might be a better investment.
* Do you need the versatility for other types of photography? If you shoot sports or wildlife in addition to portraits, the 70-200mm becomes more appealing.
* Are you comfortable with the size and weight? If you have back problems or prefer a lightweight setup, a smaller lens might be a better choice.
* Have you rented or borrowed a 70-200mm to try it out? This is the best way to determine if it's the right lens for you.
Conclusion:
A 70-200mm lens is a powerful and versatile tool for portrait photography, offering excellent compression, beautiful bokeh, and comfortable working distance. However, it's not a necessity for every portrait photographer. Consider your style, budget, and shooting environment before making a decision. If you can afford it and it aligns with your needs, it can be a fantastic addition to your kit. But don't feel pressured to buy one if other lenses would better suit your specific requirements and budget. Many professionals create stunning portraits with a variety of focal lengths.
