Best Lenses For Documentary (Cinematography) 2022

If your budget is limited and you have a camera with a standard lens, the next thing to buy is a medium telephoto lens (no zoom). This is ideal for close-ups with flat backgrounds. Next is a high-quality wide-angle lens.

For creative, narrative shots, a fixed focal length lens gives a more “cinematic” effect with less depth of field than a zoom lens. You can also buy a matching “film lens” that gives you precise control over exposure and focus, but it’s expensive. If you’re on a budget, choose a used lens with manual focus and an adapter.

For news, event, and documentary shooting, one or two good zoom lenses are a quick fix. If you can afford it, buy a fixed aperture zoom lens that covers the range from wide-angle to medium telephoto. You don’t have to change lenses, and the exposure doesn’t change when you zoom in or out. You can also choose a wide-angle or ultra-wide-angle zoom lens for handheld close-ups.

If you need a more exotic lens, such as a full-size super-wide-angle lens or a fast telephoto lens, it’s better to rent one if you’re not sure you’ll use it regularly.

Factors to consider while choosing Best Lenses For Documentary | Ultimate Guide 2022

The lens is the most important component of a camera. It is no wonder that many people have trouble replacing lenses. Good lenses are expensive and special. Whether this is the first lens you buy or your twentieth, it is important to know exactly what you are looking for. Here are the main factors to consider before investing in your next lens.

Mounting system

The first thing to consider with a lens is the type of mount. Each camera manufacturer has its own method of connecting the lens to the camera. This connection is called the mount. When purchasing a new lens, be sure to choose the right one for your camera.

Here are the typical mount systems for digital SLR cameras and mirrorless cameras. Micro Four Thirds (MFT), which is used in most cameras from Canon EF, Nikon F, Sony E-mount, Fujinon X-mount, and Panasonic. Some lens mounts are only associated with cameras from the same manufacturer, for example, some film cameras use the EF mount outside of the Canon ecosystem. There are also manufacturers that offer the same lens in several different mounts, such as Sigma, Tamron, Rokinon, and FUJINON. High-end brands such as Zeiss and Cook also offer interchangeable lens mount options.

When investing in lenses, consider the camera and mount you plan to use in the future so that you can continue to use your lens collection after your next upgrade.

Focal length

Once the compatibility is determined, the focal length will be the deciding factor in lens selection. The focal length is usually the first number listed in the lens description and is measured in millimeters. The smaller the number, the wider the angle of view and the more scenes you can capture. A lens with a longer focal length brings the viewer closer to the action and compresses the space in the image more.

Focal length is one of the major factors that determine how an image looks. When used intentionally, it is a useful storytelling tool. Extreme lenses, such as super wide angles and super-telephoto, are usually used only for specific creative effects. Very wide lenses often distort images and can be annoying in the wrong circumstances. In video production, lenses with focal lengths from 20mm to 100mm are common, with a 50mm lens roughly matching the field of view of the human eye.

You will also find that most manufacturers, including Canon, Nikon, Sony, Sigma, and Tokina, produce very similar 24-70mm zooms. This zoom range covers the most commonly used focal lengths. They are also generally affordable, ranging in price from a few hundred to several thousand yen, depending on the mount and manufacturer.

Effective Focal Length

When choosing a lens by focal length, you must also consider the size of the camera’s sensor. Sensors smaller than full size have a crop factor, which increases the effective focal length of the lens. When combined with an MFT sensor with a 2x crop factor, a 35mm lens will have an angle of view equivalent to a 70mm lens. A camera with an APS-C sensor with a crop factor of 1.5x will give the same lens an angle of view almost equivalent to a 52mm lens. Know your camera’s crop factor and get the lens you need.

Main and Zoom Lenses

Primary lenses have a fixed focal length, but a zoom lens can be used to cover a range. They can have a long or short focal length, cover a wide range, or cover only a very narrow range. Zoom lenses are generally more expensive, especially as the zoom range increases. However, they can replace several prime lenses and are useful in run-and-gun situations where you often have to crop.

There are two types of zoom lenses: built-in and external. External zooms are more common and more affordable. If you need accessories such as a matte box, you may want to opt for a built-in zoom.
Primary lenses have a fixed focal length, while zooms can cover a variety of distances.

Prime lenses, on the other hand, often have faster or wider f-numbers than zoom lenses. They also generally produce sharper images than zoom lenses because fewer lenses are used.

Aperture

An aperture is a hole in a lens that lets light in. The size of this opening is controlled by the multi-blade iris. The aperture also affects the bokeh in a photograph. The more blades there are, the more circular the aperture is, and the smoother and more beautiful the bokeh in the defocused areas.

The size of the aperture is an important indicator. It is the maximum width that can be opened. It is usually measured by the f-number of the lens, such as f/2.8, f/4, f/5.6, etc. The smaller the f-number, the larger the aperture, allowing more light through. Also, as the aperture is opened, the depth of field becomes shallower. In other words, the surface in focus becomes thinner.

A photograph in which the subject is sharp and the background is largely out of focus was probably taken with a large aperture of f/2.8 or larger. When buying a new lens, choose one with a maximum aperture of f/4 or larger. Zoom lenses often have an aperture f-number that varies with the focal length used. This means that you will probably need to adjust the exposure when zooming.

Fixed aperture zooms are easier to use but usually more expensive. Similarly, lenses with larger maximum aperture f-numbers are generally more expensive. However, going from f/4 to f/2.8 makes a big difference for videographers working in low-light situations. It is also recommended for those who want to create cinematic expressions because of its very shallow depth of field.

Sensor Size

Another important consideration when purchasing a lens is the size of the camera’s sensor. The main sensor types considered here are, in order from largest to smallest, full size, APS-C and Super35, and Micro Four Thirds MFT is both a sensor format and amount type.

Full-size sensors are the largest, so the image from a full-size lens will cover a smaller sensor. Full-size compatible lenses can be used on any camera. However, if a lens for a crop sensor is used on a full-frame camera, the image will only cover a portion of the sensor. This results in significant vignetting in the image. Avoid using lenses designed for small sensors on large format cameras unless you specifically expect this effect.

Some manufacturers use different mount subsystems that also represent the sensor size. For example, Canon’s EF mount is for full-size cameras, while the EF-S mount is for Canon crop sensors; EF-mount lenses can be used with EF-S cameras, but EF-S mount lenses will not even fit EF cameras. Full-size compatible lenses are generally more expensive, but they are also more versatile. So they are more likely to remain in your arsenal over the long term.

Adapters

An adapter to attach a lens for one mount to a camera for another mount. They can be found for most mount combinations. While they allow more lenses to be used, adapters also have their drawbacks. When using an adapter, you should always consider the size of the sensor and the coverage of the lens.

Also, few adapters allow digital communication between the camera and the lens. If digital communication is lost, autofocusing is not possible. With newer lenses, you may not be able to change the aperture. Adapters can also affect the light that passes through the lens to the sensor. Using an adapter can reduce the exposure by one point. It is a useful tool, but you should always be aware of its drawbacks if you use it.

Cinema Lenses

Cinema lenses differ from fixed lenses in several ways. First, they are more robust and have less tolerance for variations in technical characteristics. They also have a longer focal range, which allows for smoother separation and manual aperture. Cinema lenses are designed for use in adverse weather conditions. Because of these stringent specifications, they are often much more expensive than similar fixed lenses.

Also, the aperture of cinema lenses is measured in terms of T-value rather than F-value; unlike F-value, T-value is not the width of the aperture, but the amount of light reaching the sensor. This difference makes the T-stop more stable for film applications.

Some of the light entering the lens is lost as it passes through the lens and the camera; a lens with an F value of f/1.2 may have a T value of t/1.4, resulting in a slight loss of 0.2. T iris is usually found only in film lenses, as filmmakers are particularly concerned with exposure stability.

Film lenses are much more common and affordable than film zooms. It is important that cinema lenses be parfocal. This means that they maintain a constant focus over the entire area of the lens. This makes the design of cinema zooms very complex and expensive to manufacture.

Because cinematographers value consistency, major cinema lenses are often sold as a set. These lenses share the same image quality characteristics and physical design, making it easy to change lenses between shots.

Special Lens Options

AF :

Autofocus is a useful feature, but it is not as useful in motion picture productions as it is in still images, unless continuous autofocus is supported. Continuous AF is a very useful feature that allows the camera to lock onto a subject and keep it in focus as it moves across the focal plane. However, Continuous AF does not work well with some cameras, and the AF performance of lenses for video is somewhat limited.

IS:

This image stabilization function is effective in alleviating the instability of hand-held shooting. While this is a very useful feature, it does not replace Steadicam or gimbal. However, it can be effective in smoothing out minor shaking.

Aperture control:

Older lenses used manual aperture control, in which the aperture is increased or decreased by rotating a ring similar to the focus ring. This is useful when the lens is used with a camera that does not have digital communication. While most film lenses allow manual aperture control, this is not always the case with photographic lenses.

FAQs

1. What is the opening of a goal?

The aperture in your lens is the hole through which light reaches the camera sensor, or film if you’re using a film camera. The wider the aperture, the more light enters the camera. In low light conditions, it is better to have a large aperture, and when working with a lot of light it is better to adopt an aperture to avoid overexposure.

2. What is an ‘f-stop’?

Light passes through the lens aperture on its way to the camera sensor, and your lens’ f-stop refers to the amount of light it lets in. The lower the f-stop, the wider your aperture will be, and the lighter will enter the camera. The more light enters the camera, the greater the chances of the background being blurry. A lot of vloggers like to blur their background because it’s a quick way to mask the rooms they are filming in.

Conclusion.

There are many factors to consider when choosing a lens. Most important are how you will use it, what camera system it will work with, and, of course, the price. No one lens can meet all needs, and each has its own advantages and disadvantages. By gathering information and knowing your options, you will be able to find the right lens for your needs.
