Both types of lenses give you the opportunity to master a technique known as a rack focus. Rack focus is the recorded shift of focus from one object to another.

If you choose fixed focal length lenses (FFL), you will need a number of lenses with fixed focal lengths if you will be recording images with varying depths of field. A fixed focal length lens - often referred to as a prime lens - has only one focal length, which cannot be changed. Fixed focal length lenses usually provide more clarity because of less glass and come with a faster aperture. For example, the fastest aperture when shooting at 85mm on a 24-105mm lens is usually f/4-f/5.6. Fixed lenses often provide faster apertures such as f/1.2-f/1.8, which creates eye-catching critical focus on your subject, which is great for studio interviews. Unlike VFL lenses, weight does not shift as much in FFL. This makes FFL the better option to use with gimbals.

A variable focal length lens (VFL), more commonly called a zoom lens, can change focal lengths within a certain range, thereby changing the magnifying power of the lens by zooming in or out. From a stationary position, if the lens has a short focal length, the object being documented will be smaller and more of the background will be shown. From that same position, a lens with a longer focal length will make the subject larger, eliminate some of the background and exaggerate the depth of field. As an example, a 100mm lens will make the subject twice as large and show less of the background than the image produced by a 50mm lens. This effect is known as lens compression. The ability to zoom in and out with VFL lenses makes these lenses more versatile for uncontrolled action and allows you to pack less for the field.

Eyepiece: It is also referred to as the ocular. This area is used to view objects through the microscope. It is located at the tip of the microscope.

Normal lenses, also referred to as medium lenses, can be fixed or variable, and range between 24-105mm. To best replicate the human eye, use a 50mm with a full-frame sensor or a 35mm with a crop sensor. These lenses are ideal for ceremonies, historical documentation and military portraits because they don't distort the image and they recreate the scene from a natural perspective. Check whether your normal lens is variable or fixed to make sure you know if you need to bring one lens or many lenses to the shoot.

There are two types of lenses in photography and videography: variable focal length and fixed focal length. When you carry a variable focal length lens, you will be able to produce a variety of shots. If you are carrying fixed focal length lenses, you will need to change your lens to capture wide, medium and close-up shots.
