Why Opt for the 85mm F1.4 Lens over 85mm F1.8 for Portrait Photography
When considering lenses for portrait photography, many photographers might wonder why they would choose an 85mm F1.4 lens over the 85mm F1.8, given that the latter often offers similar results at a significantly lower price. Several factors contribute to the preference for the more expensive F1.4 lens, which we will explore in detail.
1. Optical Quality: Bokeh and Sharpness
One of the most appealing reasons to choose an 85mm F1.4 lens is its superior optical quality, particularly in terms of bokeh and sharpness. The wider aperture of an F1.4 lens allows for a more pleasing and smoother background blur, often referred to as bokeh. This effect can enhance the overall aesthetic of portrait photography by drawing viewers' attention to the subject.
In addition to bokeh, the F1.4 lens typically offers superior sharpness, especially in the center of the frame. This makes it an excellent choice for capturing fine details and maintaining overall image quality, even in challenging lighting conditions. Although both lenses can be sharp, the F1.4 version may provide a slight edge in areas such as skin texture and facial features, which are crucial elements in portrait photography.
2. Low Light Performance
The 85mm F1.4 lens stands out for its ability to perform exceptionally well in low-light settings. With its wider maximum aperture, this lens allows for more light to enter, which results in faster shutter speeds or lower ISO settings. This capability is particularly valuable for photographers working in dimly lit environments, such as indoor shoots or nighttime portrait sessions. The increased light sensitivity enables clearer and more detailed images, even when the lighting conditions are less than ideal.
3. Build Quality and Durability
The 85mm F1.4 lens is known for its superior build quality, featuring materials that are more durable and robust than those used in the F1.8 version. This is significant for professionals who require lenses that can withstand daily use in challenging environments. Professional-grade materials often include weather-sealing, which protects the lens from dust and moisture, and a more robust construction, ensuring that it can handle the rigors of on-location shooting.
4. Aperture Control and Creative Options
Another crucial consideration is the control over depth of field provided by the wider aperture of the F1.4 lens. A wider aperture allows for more creative control over the amount of the image that stays in focus. This is particularly useful in portrait photography, where isolating the subject from the background can create a more visually balanced image. The ability to achieve a shallower depth of field with an F1.4 lens enables photographers to emphasize the subject and blur the background, leading to more compelling and artistic portraits.
5. Professional Use and Prestige
Many professionals opt for the 85mm F1.4 lens, not just for its technical superiority but also for the prestige and recognition it brings. High-end lenses are often seen as a symbol of performance and quality, and using them can enhance a photographer's professional image. This factor is particularly important for photographers who are building or maintaining a client base that values professional-grade equipment.
Conclusion
While the 85mm F1.8 lens is an excellent option for many photographers, especially those working with limited budgets or in well-lit conditions, the 85mm F1.4 lens offers several advantages that can justify its higher price. Its superior optical quality, excellent low-light performance, and superior build quality make it an invaluable tool for professional portrait photographers. The decision ultimately comes down to individual needs, shooting style, and budget considerations. Regardless of the lens chosen, the key to success in portrait photography lies in mastering the art of composition and capturing the essence of the subject.
