Here's a breakdown to help understand the arguments for and against needing a 70-200mm for portrait photography:
Reasons Why a 70-200mm *IS* a Great Choice for Portrait Photography:
* Compression: This is the lens's biggest strength for portraits. Longer focal lengths compress perspective, making features like noses and ears appear more in proportion and generally more flattering. This compression also helps to blur the background.
* Bokeh: Especially a 70-200mm f/2.8, these lenses produce incredibly creamy and beautiful bokeh (background blur). This helps isolate your subject and creates a dreamy aesthetic.
* Working Distance: A 70-200mm allows you to maintain a comfortable distance from your subject. This can be especially helpful when photographing:
* Shy subjects: Giving them more space can make them feel more relaxed.
* Children: Allows you to capture candid moments without being right in their face.
* Large groups: You can frame groups from further back without having to shout instructions.
* Versatility: While primarily known for portraits, a 70-200mm is also useful for event photography, sports, and even some landscape work.
* Professional Impression: Let's be honest, it *looks* impressive. For some clients, seeing a photographer with a large lens can inspire confidence.
* Zoom Flexibility: You have a range of focal lengths within one lens, allowing you to quickly adjust framing without physically moving.
Reasons Why You *MAY NOT* Need a 70-200mm Lens for Portrait Photography:
* Cost: 70-200mm lenses, especially the f/2.8 versions, are expensive. There are many other excellent portrait lenses you can get for significantly less.
* Size and Weight: These lenses are large and heavy, which can be tiring to carry around for extended periods. This is especially true if you're shooting on location.
* Learning Curve: Managing the shallow depth of field at f/2.8 (or wider) and at longer focal lengths takes practice. Missed focus can be a real issue if you're not careful.
* Space Requirements: You need a good amount of space to effectively use the longer end of the 70-200mm. This can be limiting in small studios or indoor locations.
* Other Good Options Exist: Many excellent portrait lenses are available, including:
* 35mm & 50mm: Great for environmental portraits and capturing a wider view. Often more affordable and compact.
* 85mm: Considered by many to be the "ideal" portrait focal length. Offers a good balance between compression and working distance. Often available with wide apertures (f/1.4 or f/1.8) at reasonable prices.
* 100mm Macro: Excellent for details and sharp portraits. Can also be used for macro photography.
Who Benefits the Most from a 70-200mm Lens for Portraits?
* Professional portrait photographers: Especially those who shoot a variety of portrait types (headshots, families, outdoor, events).
* Photographers who frequently shoot on location: The zoom range allows for flexibility in framing without constantly moving.
* Photographers who want the best possible bokeh and compression: If creamy backgrounds and flattering perspective are a priority.
* Photographers who need to work from a distance: For shy subjects, children, or group shots.
Alternatives to Consider:
* 85mm f/1.8 or f/1.4: Often considered the classic portrait lens. Offers excellent image quality, beautiful bokeh, and a flattering focal length at a more affordable price than a 70-200mm.
* 135mm f/2: Another fantastic option for portraiture with even more compression and beautiful bokeh, though slightly more specialized.
* Prime Lenses (35mm, 50mm): For environmental portraits and capturing a wider scene. Often more affordable and sharper than zoom lenses.
In Conclusion:
A 70-200mm lens is a fantastic tool for portrait photography, offering excellent image quality, beautiful bokeh, and flattering perspective compression. However, it's not essential. Consider your budget, shooting style, space constraints, and the types of portraits you shoot before deciding if it's the right lens for you. There are many other excellent portrait lenses available that may be a better fit for your needs and budget. Try renting one before you buy to see if it suits your style.
