Here's a breakdown of the arguments for and against, along with alternative lens options:
Arguments for Needing a 70-200mm Lens for Portraits:
* Excellent Compression: This is the biggest draw. The longer focal lengths (especially 135mm and beyond) create a flattering compression effect, making features appear more proportional and minimizing the emphasis on potentially unflattering features. The background also appears closer to the subject, creating a more intimate feel.
* Beautiful Bokeh: 70-200mm lenses, especially those with wide apertures (f/2.8 being common), are renowned for creating creamy, dreamy bokeh (background blur). This helps isolate the subject and adds an artistic touch to the image.
* Working Distance: It allows you to stand further back from your subject. This can be beneficial for several reasons:
* Less Intrusive: Some subjects feel more comfortable when you're not right in their face.
* Candid Moments: It allows you to capture more natural, unposed expressions.
* Flexibility: You can easily switch between tighter headshots and wider shots without moving much.
* Versatility: While primarily used for portraits, a 70-200mm lens can also be used for other genres like sports, wildlife, and event photography, making it a good investment if you shoot a variety of subjects.
* Professional Look: Using a 70-200mm often gives your work a more polished and professional aesthetic, particularly when combined with good lighting techniques.
* Zoom Capability: The zoom range allows for a variety of framing options without physically moving, especially in dynamic environments. You can quickly go from a headshot to a half-body shot.
Arguments Against Needing a 70-200mm Lens for Portraits:
* Cost: 70-200mm lenses, especially those with wide apertures, are generally expensive. It's a significant investment.
* Size and Weight: They are bulky and heavy, which can be tiring to carry around for extended periods.
* Requires Space: You need a decent amount of space to use the longer focal lengths effectively. It might not be ideal for small studios or cramped locations.
* Not Always Necessary: Many beautiful portraits can be taken with shorter focal lengths. Style and artistic vision are ultimately more important than the lens itself.
* Learning Curve: While not overly complicated, mastering the compression and working distance takes some practice.
Alternative Lens Options for Portraits:
* 50mm Lens: A "nifty fifty" is a classic portrait lens. It's affordable, lightweight, and can produce beautiful results. Requires you to get closer to the subject.
* 85mm Lens: Another popular portrait lens. It offers a good balance between compression and working distance, and is often considered the "sweet spot" for portraiture by many.
* 35mm Lens: Wider focal lengths can be used for environmental portraits, showing the subject in their surroundings. Requires careful consideration of perspective.
* Prime Lenses (Fixed Focal Length): Prime lenses generally offer wider maximum apertures and sharper image quality than zoom lenses at a comparable price point. You might consider an 85mm f/1.4 or a 135mm f/2 as alternatives.
* Other Zoom Lenses: Lenses like a 24-70mm or a 24-105mm can also be used for portraits, though they won't offer the same level of compression or bokeh as a 70-200mm.
Ultimately, the decision of whether or not to buy a 70-200mm lens depends on:
* Your Budget: Can you afford the lens without sacrificing other important equipment or resources?
* Your Style: What kind of portraits do you like to shoot? Do you prefer tight headshots with blurry backgrounds, or wider environmental portraits?
* Your Space: Do you have enough space to work with longer focal lengths?
* Your Needs: Do you also shoot other genres of photography where a 70-200mm would be useful?
* Your Preference: Try renting or borrowing a 70-200mm lens and see if you like the results. Experiment with different focal lengths and see what you prefer.
In Conclusion:
While not absolutely essential, the 70-200mm lens is a highly valuable tool for portrait photographers, offering excellent compression, beautiful bokeh, and versatility. If you have the budget and space, it's definitely worth considering. However, you can absolutely create stunning portraits with other lenses, particularly primes like the 50mm, 85mm, or 135mm. The best lens is the one that helps you achieve your artistic vision and meet the needs of your clients. Try before you buy, if possible!
