Understanding 85mm in Inches: A Comprehensive Guide

Introduction

In the realm of photography, understanding the relationship between millimeters (mm) and inches is crucial for selecting the appropriate lens for your camera. One of the most versatile focal lengths in photography is 85mm, which offers a flattering perspective for portraits and a wide range of other applications. In this comprehensive guide, we will explore the intricacies of 85mm in inches, its advantages, and how to effectively use it in your photography.

85mm vs Inches: A Detailed Conversion

As a general rule, 1 inch is approximately equal to 25.4 millimeters. Therefore, 85mm is equivalent to:

85mm / 25.4 = 3.35 inches

This conversion is important to keep in mind when choosing a lens for your camera, as different lens manufacturers may list their focal lengths in either millimeters or inches.

Advantages of Using an 85mm Lens

85mm lenses offer several benefits for photographers, including:

• Classic Perspective for Portraits: 85mm is considered an ideal focal length for capturing flattering portraits. It produces a natural perspective that emphasizes the subject's features while maintaining a pleasing background blur.
• Versatile for Other Applications: While primarily known for portraits, 85mm lenses can also be used effectively for street photography, travel photography, and even weddings. The moderate focal length allows for both close-up and environmental shots.
• Fast Aperture: Many 85mm lenses feature a wide maximum aperture, such as f/1.2, f/1.4, or f/1.8. This allows for excellent low-light performance and the ability to create a shallow depth of field for isolating your subject.
• Excellent Optical Quality: 85mm lenses are typically designed with high-quality optics, resulting in sharp images with minimal distortion and vignetting.

Effective Strategies for Using an 85mm Lens

To maximize the potential of an 85mm lens, consider the following strategies:

• Distance from your Subject: The distance from your subject will significantly impact the perspective and blur in your images. For portraits, you will generally want to be 5-8 feet away from your subject.
• Aperture Selection: The aperture you choose will control the depth of field and the amount of blur in your images. Wider apertures (smaller f-numbers) will create a shallower depth of field, while narrower apertures (larger f-numbers) will result in a greater depth of field.
• Composition: Use the focal length to your advantage by framing your subject in a flattering way. Look for natural lines and shapes in your background to create depth and interest.

Common Mistakes to Avoid

To avoid common pitfalls when using an 85mm lens:

• Camera Shake: Due to the relatively long focal length, 85mm lenses are more susceptible to camera shake. Use a tripod or stabilize your camera whenever possible to prevent blurry images.
• Focusing Errors: Ensure accurate focus by using the appropriate autofocus mode and focusing on the subject's eyes. Manual focus can also be helpful in certain situations.
• Overuse of Shallow Depth of Field: While a shallow depth of field can be beautiful, avoid using it excessively. Excessive blur can distract from the subject and make your images appear cluttered.

Step-by-Step Approach to Using an 85mm Lens

1. Choose the Right Lens: Consider the specifications of your camera and select an 85mm lens that is compatible.
2. Set Up Your Camera: Mount the lens on your camera and adjust the appropriate settings, such as aperture, shutter speed, and ISO.
3. Position Yourself: Stand at a suitable distance from your subject, typically 5-8 feet for portraits.
4. Focus and Compose: Use autofocus or manual focus to ensure your subject is sharp. Compose your shot carefully, considering the background and framing.
5. Capture the Image: Take the shot and review it to ensure it meets your expectations.
