Here's a breakdown of the arguments for and against:
Arguments for needing a 70-200mm lens for portraits:
* Compression: This is perhaps the biggest draw. The longer focal lengths compress the background, making it appear closer to the subject and creating a more flattering perspective. It minimizes distortion, especially noticeable on facial features.
* Background Blur (Bokeh): The longer focal lengths, coupled with a wide aperture (f/2.8 is ideal but f/4 can also work), allow for incredibly creamy and beautiful background blur, isolating the subject and creating a professional look.
* Working Distance: A 70-200mm allows you to be further away from your subject. This can be beneficial for a few reasons:
* Comfort: Some people are more relaxed and natural when they're not being stared at from just a few feet away.
* Candid Moments: You can capture genuine expressions and interactions without being intrusive.
* Control the Environment: Sometimes stepping back lets you frame your subject better within the background.
* Versatility: The zoom range is incredibly versatile. You can shoot tight headshots at 200mm and wider environmental portraits at 70mm, all with the same lens.
* Professional Impression: For some clients, seeing a photographer with professional-looking equipment (and a 70-200 is often perceived as a hallmark of professional gear) can inspire confidence.
* Outdoor Portraits: In outdoor settings, the ability to reach out and isolate your subject from a busy background is invaluable.
* Event Photography (with a portrait slant): If you also shoot events and want to capture portraits while doing so, the 70-200mm is a must-have.
Arguments against needing a 70-200mm lens for portraits:
* Cost: High-quality 70-200mm lenses, especially those with a fast aperture (f/2.8), can be very expensive. This is a significant barrier for entry for many photographers.
* Size and Weight: These lenses are large and heavy, making them less convenient for travel or longer shoots. This can lead to fatigue and missed shots.
* Indoor Limitations: In smaller indoor spaces, a 70-200mm can be too long to use effectively. You might find yourself constantly bumping into things or unable to get the shot you want.
* Not Essential for All Styles: If you primarily shoot environmental portraits where the background is an important element of the image, other lenses might be more suitable.
* Alternatives Exist: There are many other excellent portrait lenses, such as:
* 35mm: Great for environmental portraits and street photography.
* 50mm: Versatile, affordable, and a classic portrait lens.
* 85mm: A popular choice for portraits due to its flattering perspective and ability to create background blur.
* 105mm Macro: Can be used for stunning close-up portraits and offers beautiful bokeh.
In Conclusion:
A 70-200mm lens is an *excellent* tool for portrait photography, offering a lot of versatility and the ability to create professional-looking images with beautiful compression and background blur. However, it's not strictly necessary. Consider your style, subject matter, budget, and shooting environment before making a decision.
Here's a good way to decide:
* Try before you buy: Rent a 70-200mm lens for a weekend and see if it fits your workflow and shooting style.
* Assess your needs: Do you often find yourself wishing you could zoom in further and create more background blur? Are you shooting in environments where you need more working distance?
* Consider alternatives: Could an 85mm or 135mm prime lens give you the desired look at a lower cost and weight?
Ultimately, the best lens for portrait photography is the one that helps you create the images you envision and fits comfortably within your workflow and budget. Don't let the hype surrounding the 70-200mm pressure you into buying one if it's not the right fit for you.
