Arguments FOR needing a 70-200mm lens for portrait photography:
* Compression: This is the big one. The 70-200mm lens, especially at the longer end, offers excellent compression. This makes the background appear closer to the subject, creating a more intimate and flattering image. It minimizes distortion and can make features like noses appear smaller and more pleasing.
* Bokeh: The shallow depth of field achievable with a 70-200mm lens (especially at larger apertures like f/2.8 or f/4) can create beautifully blurred backgrounds (bokeh) that isolate the subject and draw attention to them. This is highly desirable for many portrait styles.
* Working Distance: Allows you to maintain a comfortable distance from your subject, which is crucial for candid or natural-looking portraits. It can be less intimidating than having a wide-angle lens right in their face.
* Versatility: While known for portraits, the 70-200mm is also great for events, sports, wildlife, and even landscape photography. It's a versatile lens that can be used in various situations.
* Reach: Ideal for shooting in crowded environments or when you can't physically get closer to your subject. You can isolate individuals or capture details from a distance.
* Professional Look: The 70-200mm is often seen as a staple in a professional photographer's kit. Clients may subconsciously perceive you as more credible and capable.
Arguments AGAINST needing a 70-200mm lens for portrait photography:
* Price: Good 70-200mm lenses can be expensive. This is a significant investment, especially for beginners.
* Size and Weight: These lenses are large and heavy, making them less portable and potentially tiring to use for extended periods.
* Limited Indoor Use: The long focal length can be restrictive in smaller indoor spaces. You might not have enough room to get the composition you want.
* Alternative Options: Other lenses can achieve similar results, depending on your style:
* 35mm or 50mm: Excellent for environmental portraits where you want to show the subject in their surroundings.
* 85mm: Considered a classic portrait lens, offering a good balance between compression and working distance.
* Not Suitable for Every Style: If you prefer wide-angle, environmental portraits, or close-up, intimate shots, a 70-200mm might not be the best choice.
* Dependence Creates Laziness: Some argue that relying solely on the 70-200mm can limit creativity. It can discourage photographers from exploring different perspectives and compositions.
So, DO You *Really* Need It?
Here's a more nuanced approach:
* If you regularly shoot portraits outdoors, especially full-body or half-body shots, and value compression and beautiful bokeh, then a 70-200mm is an excellent investment.
* If you primarily shoot in studios or cramped indoor spaces, and prefer tighter headshots or environmental portraits, then other lenses like an 85mm or even a 50mm might be more suitable.
* If you're a beginner on a tight budget, consider starting with a more affordable prime lens like a 50mm or 85mm to learn the fundamentals of portrait photography. You can always add a 70-200mm later.
* Rent a 70-200mm lens for a few days to see if it fits your style and workflow before committing to a purchase. This is the best way to determine if it's truly a "need" for you.
In summary: The 70-200mm lens is a powerful and versatile tool for portrait photography, but it's not a universal requirement. Consider your individual needs, shooting style, and budget before making a decision. There are plenty of successful portrait photographers who don't own a 70-200mm lens, and many who swear by it. The most important thing is to choose the tools that help you achieve your creative vision.
