Understanding the Significance of 85mm in Inches: A Comprehensive Guide

When it comes to understanding measurements, it's crucial to grasp the conversion between different units. One such conversion that is often encountered in photography, cinematography, and many other fields is the conversion between millimeters (mm) and inches (in). In this article, we will delve into the conversion of 85mm to inches, exploring its significance and various applications.

Conversion: 85mm to Inches

The conversion from millimeters to inches is straightforward. One millimeter is equal to 0.0393701 inches. Therefore, to convert 85mm to inches, we can use the following formula:

85mm x 0.0393701 in/mm = 3.34646 inches

Hence, 85mm is equivalent to approximately 3.346 inches.

Significance of 85mm in Photography

In the realm of photography, the 85mm focal length holds a prominent place. Popularly known as a portrait lens, an 85mm lens produces flattering portraits with a shallow depth of field. This helps in isolating the subject from the background, creating a visually pleasing effect.

85mm Lenses for Different Camera Formats

Depending on the camera format, the field of view and the effective focal length of an 85mm lens will vary:

Choosing the Right 85mm Lens

Selecting the appropriate 85mm lens depends on several factors, including:

• Aperture: Wider apertures (such as f/1.4 or f/1.8) offer a shallower depth of field for more pronounced background blur.
• Image Stabilization: Lenses with built-in image stabilization (IS) help reduce camera shake, allowing for sharper handheld shots.
• Autofocus Speed and Accuracy: Fast and precise autofocus capabilities ensure sharp images, especially for moving subjects.

Benefits of Using an 85mm Lens

• Subject Isolation: Shallow depth of field isolates the subject, drawing attention to them.
• Flattering Portraits: 85mm lenses produce flattering facial features and minimize distortion.
• Versatility: 85mm lenses can also be used for street photography, travel photography, and even close-ups.

Comparison of 85mm Lenses

The following table compares three popular 85mm lenses from different manufacturers:

Tips for Using an 85mm Lens

• Position Yourself: Stand at a distance of 6-8 feet from the subject to achieve the classic portraiture look.
• Use a Wide Aperture: Wider apertures create a shallower depth of field, blurring the background.
• Pay Attention to Lighting: Good lighting enhances the overall image quality. Use natural light or external flash for optimal results.
• Consider a Tripod: A tripod provides stability and reduces camera shake for sharper images.

Effective Strategies

• Master Composition Techniques: Understand the principles of composition to create visually appealing portraits.
• Experiment with Different Apertures: Varying the aperture changes the depth of field and background blur.
• Utilize Natural Lighting: Leverage natural light to enhance skin tones and create flattering portraits.

Conclusion

Understanding the conversion between 85mm and inches (approximately 3.346 inches) is essential for accuracy in various fields, especially photography. 85mm lenses are highly versatile and produce stunning portraits with a shallow depth of field. By choosing the right 85mm lens and utilizing effective strategies, you can capture captivating images that showcase the subject in an appealing and flattering manner.
