Canon 400mm Camera Lenses

Cleaning and Taking Care of 400 mm Camera Lenses

Being a photography enthusiast can be expensive, especially when you are investing in lenses by Canon. Find out how you can make the most of your Canon EF lens and use it as long as possible.

What Are the Special Attributes of a 400 mm Focal Length Lens?

A 400 mm lens is a telephoto type of lens. It is used mostly by photographers who want to take pictures of objects from great distances like a photo of the moon, long-range wildlife photography, or a panorama of a far-off mountain range. Other traits of the 400 mm lens include:

• Exceptional Sharpness - Increased sharpness allows the viewer of the image to see the intricate details of a subject that is shot from a far distance. Sharp images mean better clarity.
• Less Vignetting - Vignetting is the softening or shading of photograph edges. This can distract the viewer from the central subject of the photo.
• Low Distortion - Distortion is the noise of an image that makes it difficult to see the detailed likeness of the original subject. Sharp pictures with high distortions can ruin image quality.
• Less Image Correction - Many photographers have to edit their photos off-camera, but a 400 mm lens can render images that need no correction. This prevents chromatic aberrations as well.
• Intricate Zoom Features - A 400 mm lens has more zooming capabilities than its lower range counterparts.
• Higher Maximum Aperture - The lens offers a better option when choosing aperture levels.

What Are The Parts of a 400 mm Lens?

Because of its size, the EF 400 mm telephoto lens has many parts that are vital in keeping it intact and safe from the elements. Unlike lenses from other digital cameras, the 400 mm USM super telephoto lens has more complex components. These include:

• A lens hood to protect the super-telephoto type lens from the elements.
• EF or electro-focus lens for better visuals.
• USM or ultrasonic motor for the mechanics of the zoom feature.
• Image Stabilization Component that prevents blurring.

How to Care for Your Super-Telephoto Lenses

Because of its size and features, the 400 mm can be a very valuable piece of photography equipment. You must care for it well so that you can use it for a long time. Here's how:

• Always use the lens cover when not using the lens.
• Clean the lens after each use to preserve hardware and image quality.
• Use a detachable hood if there is no built-in hood. This will protect your EF or USM lens from the elements.
• When using a tripod, make sure that it is designed to carry the weight of a 400 mm lens.
• Ensure that the detachable tripod is stabilized on the ground as well to prevent the camera from tipping.
• Clean the built-in components using proper cleaning gear and materials.
