Here's a breakdown of the pros and cons to help you decide:
Why the 70-200mm is a Powerhouse for Portraiture:
* Compression: This is the big one. Longer focal lengths (especially beyond 100mm) provide flattering compression. They minimize perspective distortion, making features look more proportional and generally more appealing. This compression helps to separate the subject from the background, creating a more pleasing aesthetic.
* Bokeh (Background Blur): While aperture plays a huge role, the longer focal length combined with a wide aperture (like f/2.8, which many 70-200mm lenses offer) delivers beautiful, creamy bokeh. This helps to isolate your subject and draw attention to them.
* Working Distance: The 70-200mm allows you to stand further away from your subject. This can be incredibly helpful for several reasons:
* Comfort: Some people are uncomfortable with a lens right in their face. The distance allows them to relax and be more natural.
* Candid Shots: You can capture more candid moments without being intrusive.
* Outdoor Versatility: Gives you flexibility in outdoor environments, especially when you want to isolate your subject amidst a distracting background.
* Less Distortion with Groups: When shooting groups, the distance helps reduce perspective distortion, making subjects on the edges appear less stretched.
* Versatility: While primarily a portrait lens, the 70-200mm can also be used for other types of photography, such as sports, wildlife, and events. This makes it a versatile investment.
* Sharpness: Most 70-200mm lenses are incredibly sharp, delivering crisp details in your portraits.
* Zoom Flexibility: The zoom range allows you to quickly adjust your framing without having to physically move, saving time and effort during a shoot.
* Professional Look and Feel: Let's be honest, a 70-200mm lens *looks* impressive, and can give clients more confidence in your abilities.
The Downsides of the 70-200mm:
* Price: Good 70-200mm lenses are expensive, especially those with a constant f/2.8 aperture and image stabilization.
* Size and Weight: These lenses are large and heavy, which can be tiring to carry around for long periods. This can be particularly challenging for on-location shoots.
* Requires Space: The longer focal lengths require more space to work, which can be limiting in small studios or indoor environments.
* Not Ideal for Environmental Portraits: While you can use it for environmental portraits, it's not always the best choice. Wider lenses are generally better for capturing the subject within their surroundings.
* Can be Overwhelming for Beginners: The technical aspects of using a longer lens (like managing shallow depth of field and camera shake) can be a bit overwhelming for beginners.
Alternatives to the 70-200mm:
* 85mm Prime: A popular and affordable alternative. Offers excellent image quality, beautiful bokeh, and is generally more compact and lightweight. Lacks the zoom flexibility.
* 50mm Prime: A very affordable and versatile option. Good for environmental portraits and can produce pleasing bokeh, but requires you to get closer to your subject. Not ideal for the compression effect of longer lenses.
* 135mm Prime: A fantastic option that offers similar compression and bokeh to a 70-200mm. Often sharper and lighter but lacks versatility.
* Mid-Range Zoom (e.g., 24-70mm, 24-105mm): These lenses offer a wider range of focal lengths, making them more versatile for different types of photography. However, they typically don't offer the same level of compression or bokeh as a 70-200mm.
* Variable Aperture 70-300mm: A more affordable alternative for the 70-200, but usually with a variable aperture that gets smaller as you zoom in, and often doesn't have the same image quality.
Who *Needs* a 70-200mm (or Would Benefit Greatly):
* Professional Portrait Photographers: If you make a living taking portraits, the 70-200mm is a worthwhile investment for its image quality, versatility, and professional appeal.
* Photographers Who Shoot Primarily Outdoors: The extra reach and ability to isolate subjects are invaluable in outdoor environments.
* Photographers Who Value Compression and Bokeh: If you prioritize these aesthetic qualities, the 70-200mm is hard to beat.
* Photographers Shooting Events or Large Groups: The ability to zoom in and out quickly is crucial for capturing dynamic moments at events.
Who Might Be Okay Without a 70-200mm:
* Beginner Portrait Photographers: Start with a more affordable prime lens like an 85mm or 50mm to learn the fundamentals of portraiture.
* Photographers Who Primarily Shoot Indoors in Small Spaces: The longer focal lengths may be too restrictive.
* Photographers on a Tight Budget: There are excellent alternatives that offer great image quality at a lower price.
* Photographers Who Prefer Environmental Portraits: A wider lens might be a better choice.
Conclusion:
The 70-200mm lens is a fantastic tool for portrait photography, offering unique advantages in terms of compression, bokeh, working distance, and versatility. However, it's not essential, and there are viable alternatives. Consider your shooting style, budget, and the type of portraits you want to create before making a decision. If you can afford it and it fits your workflow, the 70-200mm can be a game-changer for your portrait photography. If not, don't feel like you're missing out; there are plenty of other great lenses to choose from.
