The lens on the camera

Before creating a timelapse from photos with the Tikee camera by Enlaps, it’s crucial to understand the technical aspects of the camera lens. A deep knowledge of these technicalities sets professional photographers apart from novices.

Whether you are a seasoned photographer/videographer or just starting out, comprehending the functions and components of a camera lens is essential. This guide focuses on the prime functions and various components of a camera lens, helping you choose the best lens for your Tikee camera by Enlaps and enhance your timelapse projects.

What is a camera lens?

Technically, a camera lens is an optical body featuring a single lens or multiple lenses. It is mounted on the camera. It is important to note that some lenses can be interchanged, and others are  fixed on  the camera body, and you cannot add or remove them.

How do camera lenses work?

• The amount of light that can pass through the lens is dictated by the aperture.

• The function of the lens is to  focus the light on the image sensor or film plane.

Further, understanding the functioning of the camera lens

is crucial, especially with brands like Canon, Nikon, Sony, and Enlaps offering a wide range of high-quality cameras.

Focal Length

When you are into professional photography, you should understand the term 'focal length'. The technical definition of focal length is the distance between the camera sensor and the optical center of the lens. The optical center refers to the place where light rays converge in the body of the camera lens. It basically defines the field of view and magnification (or zoom) for the camera lens, and is measured in mm.

Significance of Focal Length

• It dictates what part of your image should be focused and isolated from the other elements of an image .

• Focal length helps to generate the visual context of the shots or format.

• You can later change  the visual properties while shooting with the help of focal length.

• If your camera lens is longer, you will get a narrow image, whereas if the camera lens is wide, you can capture more area.

Camera Lens Aperture

The prime function of the camera lens aperture is to control the light that passes through the lens and goes to the film. It is basically measured in F-stops (estimated measurement) or T-stops (exact measurement).

It is important to understand that T-stop and F-stop are not the same. Professional photographers use T-stops, and they describe the best camera lenses. However, both of them, T-stop and F-stop, refer to the aperture stops.

For a basic understanding, remember that the lower the stop number, the higher its aperture. It means T3 is higher than T5. If you have a camera lens with a higher-stop rating and wider openings, it would allow more light and help you film in darker places and get a tidy result.

Shutter Speed

When you prepare to shoot the timelapse video, the shutter speed is measured in fractions of seconds. Shutter speed refers to the amount of time for which the shutter remains open. In the case of video recordings, it is measured in fractions of seconds.

In the case of still photography or telephoto, your camera's shutter speed is very less rigid compared to cinema and television. However, you would want the shutter speed to double your frame rate in the case of video recording.

Depth of Field

The depth of the field refers to the focus of your image and how much of it is in focus. When the depth of field is shallow, you will get a blurred background, and when the depth of field is wide , the background is very clear.

You can use a shallow depth of field when you want to emphasize only a specific part or angle of your frame so that the viewer can only focus on the important part of the picture.

Aspect Ratio

Its sensor size or film size obtains the aspect ratio of the camera lens. If the lens is manufactured for an APS-C (Advanced Photo System type-C) sensor, it will not line up properly with a full-frame camera. The mount might be correct, so attaching it physically will have no issues, but its opening size will not be correct.

Lens breathing

Lens breathing refers to the amount of shift in the angle of view while focusing. Reputed manufacturers will remove the breathing entirely. However, if you have rented a camera, it would be wise to check if it has a little breathing or not.

Breathing is hardly an issue in still photography because it is in a single image. However, when it comes to video shooting, you might want to be extra careful since you want everything to be very tidy.

Chromatic Aberration

When your lens fails to focus all colors to the same convergence point, you may refer to it as chromatic aberration. It reflects as “fringes” of color along the boundaries that keep the dark parts of your image and the light separate.

Bokeh

When your lens renders out-of-focus points of light, it is called Bokeh, which means “blur” or “haze.”

Focus Throw

It is the physical rotation of the focus ring from minimum focus distance to infinity. It is measured in degrees. A still photo camera lens would have a lower focus throe compared to a professional cinema lens. Your focus pull would be more accurate if more degrees are available.

In still photography, focus pull can shake the lens, and you will not get a decent  picture.
