Here's a breakdown of the pros and cons to help you decide if it's right for you:
Advantages of the 70-200mm Lens for Portrait Photography:
* Compression: This is a key benefit. Longer focal lengths like 70-200mm create flattering compression in portraits. It minimizes perspective distortion, making subjects appear more naturally proportioned and less "stretched" (especially noticeable on facial features). It visually reduces the space between elements in the background, creating a pleasing, cohesive look.
* Background Blur (Bokeh): The 70-200mm, often coupled with a wide aperture (f/2.8 is common, but f/4 is available too), excels at creating beautiful, creamy bokeh. This helps isolate your subject from the background, drawing attention to them and creating a professional look.
* Working Distance: Allows you to maintain a comfortable working distance from your subject. This can be crucial for:
* Candid Shots: You can capture more natural, unposed expressions without being right in your subject's face.
* Shooting Shy Subjects: Some people are more comfortable being photographed from further away.
* Outdoor Shoots: Allows you to shoot from a distance while avoiding obstacles.
* Directing without Intruding: You can direct your subject without feeling like you're crowding them.
* Versatility: While primarily used for portraits, the 70-200mm is versatile enough to be used for other types of photography, such as events, sports, and wildlife. This makes it a valuable lens to have in your kit.
* Image Quality: High-quality 70-200mm lenses (especially those with a constant f/2.8 aperture) are known for their excellent sharpness, contrast, and color rendition.
* Zoom Flexibility: The zoom range allows you to quickly and easily adjust your framing without having to move. This is especially helpful in dynamic shooting situations.
Disadvantages of the 70-200mm Lens for Portrait Photography:
* Price: 70-200mm lenses, especially the f/2.8 versions, are typically expensive. This can be a significant barrier to entry for beginner photographers.
* Size and Weight: These lenses are large and heavy, making them less convenient for travel and handheld shooting for extended periods. This can be fatiguing.
* Indoor Use (Sometimes): In small indoor spaces, the 70mm minimum focal length might be too long to get the shot you want. You may need a wider lens for tighter environments.
* Subject Distance (Can be a Problem): Sometimes you WANT to be closer to your subject to build rapport and connect. The 70-200mm's distance can sometimes hinder this.
Alternatives to the 70-200mm:
* 50mm Lens: Affordable and versatile, a 50mm (especially with a wide aperture like f/1.8 or f/1.4) can produce beautiful portraits. It's great for tighter spaces. However, it lacks the compression of a longer lens.
* 85mm Lens: Considered by many to be the ideal portrait lens. It offers a good balance of compression, bokeh, and working distance. More expensive than a 50mm, but often cheaper and lighter than a 70-200mm.
* 100mm/135mm Lens: Offer even more compression than an 85mm, but may require even more distance from your subject. Excellent for headshots and portraits where background isolation is key.
* Zoom Lenses in Different Ranges: While not offering the *exact* same benefits, zoom lenses like a 24-70mm can be versatile and get you close enough to the 70-200mm look in some situations.
Who *Needs* a 70-200mm Lens?
* Professional Portrait Photographers: If you're making a living from portrait photography, the 70-200mm is a worthwhile investment due to its image quality, versatility, and ability to create professional-looking results.
* Photographers Who Frequently Shoot Outdoors: The reach of the 70-200mm is especially useful in outdoor locations where you have more space to work.
* Photographers Who Value Compression and Bokeh: If you prioritize these aspects of portrait photography, the 70-200mm is an excellent choice.
* Photographers Who Already Have Other Portrait Lenses: If you already own a 50mm or 85mm lens and want to expand your options, the 70-200mm can be a great addition to your kit.
Who *Doesn't Need* a 70-200mm Lens?
* Beginner Photographers: If you're just starting out, it's better to invest in a more affordable and versatile lens like a 50mm or 85mm.
* Photographers Who Primarily Shoot Indoors in Small Spaces: The 70mm minimum focal length might be too long for indoor use.
* Photographers on a Tight Budget: There are more affordable portrait lens options available.
* Photographers Who Prioritize Portability: The 70-200mm is a large and heavy lens.
Conclusion:
The 70-200mm is a fantastic lens for portrait photography, offering significant advantages in terms of compression, bokeh, working distance, and image quality. However, it's not an absolute necessity. Consider your budget, shooting style, and needs before investing in one. A 50mm or 85mm lens might be a better choice for beginner photographers or those on a tight budget. If you're a professional portrait photographer or someone who frequently shoots outdoors and values compression and bokeh, the 70-200mm is a worthwhile investment. Renting one to try it out before buying is always a good idea!
