Here's a breakdown of the pros and cons of a 70-200mm lens for portrait photography, and alternatives to consider:
Arguments FOR a 70-200mm Lens:
* Compression: The longer focal lengths (135mm-200mm) create beautiful compression, minimizing perspective distortion and making the subject's features appear more pleasing and natural. This is particularly effective for headshots and tighter portraits. Backgrounds also appear closer, which can be used creatively to highlight or blur elements behind the subject.
* Bokeh: Many 70-200mm lenses have wide maximum apertures (f/2.8 is common, even f/4 is good), allowing for incredibly shallow depth of field and creamy, blurred backgrounds (bokeh). This helps isolate the subject and create a visually appealing aesthetic.
* Working Distance: The zoom range allows you to maintain a comfortable distance from your subject, especially helpful for shy subjects or when you need to avoid casting shadows. This can make the session more relaxed and result in more natural expressions. You can also shoot from a distance where you are less distracting, capturing candid moments more easily.
* Versatility: While primarily considered a portrait lens, a 70-200mm is also excellent for events, sports, and wildlife photography, making it a versatile investment.
* Professional Look: A 70-200mm lens, especially an f/2.8 version, often conveys a professional image to clients, which can be valuable for attracting business.
* Zoom Flexibility: The zoom range is useful for quickly adjusting your framing without physically moving. This is invaluable when photographing moving subjects or in quickly changing environments.
* Image Quality: High-end 70-200mm lenses are often incredibly sharp and offer excellent image quality.
Arguments AGAINST a 70-200mm Lens:
* Price: 70-200mm f/2.8 lenses are typically expensive, often costing several thousand dollars. Even f/4 versions can be pricey.
* Size and Weight: These lenses are large and heavy, which can be tiring to carry for extended periods, especially during on-location shoots.
* May not be ideal for tight spaces: In small studios or cramped locations, a 70-200mm might be too long, forcing you to stand too far away.
* Reliance on Bokeh: While beautiful bokeh is a hallmark of this lens, some photographers might prefer more environmental portraits with greater depth of field.
* Alternatives exist: Excellent portrait results can be achieved with prime lenses (like 35mm, 50mm, 85mm), which are often sharper and have wider apertures at a lower cost.
Alternatives to a 70-200mm Lens for Portraits:
* 85mm Prime Lens: This is a classic portrait lens that provides excellent compression and bokeh, is generally sharper than a zoom, and often comes in affordable f/1.8 or f/1.4 options. It's often considered *the* go-to portrait lens by many.
* 50mm Prime Lens: A versatile and affordable option. While it doesn't offer the same compression as an 85mm or 70-200mm, it can still produce beautiful portraits, especially in environmental settings. Also available in very fast apertures (f/1.4, f/1.2).
* 35mm Prime Lens: Ideal for environmental portraits, capturing the subject within their surroundings. Good for telling a story and capturing more of the context.
* 135mm Prime Lens: Offers great compression and bokeh, often at a more affordable price than a 70-200mm.
* Zoom Lenses (24-70mm, 24-105mm): These offer versatility and can be used for portraits, although they may not provide the same level of compression or bokeh as a 70-200mm or prime lens.
* Budget 70-300mm zoom lenses: These are viable options if you need the zoom range and are on a tight budget, but expect compromises in image quality and maximum aperture.
Who REALLY needs a 70-200mm?
* Professional Portrait Photographers: If you specialize in portraits and can afford it, a high-quality 70-200mm f/2.8 is a fantastic tool to have in your kit. The flexibility, image quality, and professional image it conveys are significant benefits.
* Event Photographers: The zoom range is incredibly useful for capturing candid portraits at weddings, parties, and other events.
* Photographers Who Shoot in Various Environments: If you need to be able to quickly adapt to different shooting situations and distances, the zoom range is a major advantage.
* Photographers Focused on Headshots and Close-Ups: The compression and subject isolation capabilities are ideal for these types of portraits.
* Photographers who frequently shoot outdoors and need the flexibility to work at various distances.
Conclusion:
A 70-200mm lens is a powerful and versatile tool for portrait photography, but it's not an absolute necessity. Consider your budget, shooting style, and the types of portraits you want to create. If you're on a budget or primarily shoot in tight spaces, a prime lens like an 85mm or 50mm might be a better choice. However, if you value versatility, compression, and the ability to work at a comfortable distance, a 70-200mm lens can be a worthwhile investment.
Before purchasing, consider renting a 70-200mm lens to see if it fits your needs and shooting style. You can also try comparing images taken with different focal lengths (e.g., 50mm, 85mm) to see which look you prefer.
