Lens fungus is a combination of dust and moisture that finds its way into the interior elements of a camera lens. Dust does not typically cause a problem, but if that dust contains fungus spores and combines with moisture, then fungus can grow. It is more common with lenses that are not...
What is OIS Camera movements caused by shaky hands or other external factors are among the causes of blurry photos. Optical Image Stabilization (OIS) technology helps minimize blurriness by automatically adjusting the camera lens to counteract minor movements during the exposure. Note: OIS does not ...
Focus breathing is a term that is often used when discussing the features and specs of a camera lens. It is an issue that occurs across a wide range of lenses, and it is one that can negatively affect your photography and videography in certain situations. In this article, we will take ...
F-stopis the term used to denote aperture measurements on your camera. Theaperturecontrols the amount of light that enters the camera lens, and it’s measured in f-stops. Along with shutter speed andISO(sensitivity to light), aperture is the third fundamental component that makes up the expo...

If you choose to shoot wide open, watch for the narrow depth of field and make sure your subject is in focus. Smaller f-stops such as f/16 let in less light, which allows the lens to pinpoint the sun as a small, star-like pattern. Image by Aubry Healy Time of day At sunrise...
the lens is stopped down to its minimum aperture, which is why aperture ghosting is typically not visible at large apertures like f/1.4, but quite noticeable at something like f/16. So if you see polygon-shaped ghosts in your shots, just know that those are coming from the lens diaphragm...
If you recall, the two basic things you have control over when you’re taking a photo are the shutter speed your camera uses and the aperture of the lens. The shutter speed is measured in seconds or fractions of a second while aperture is measured in f-stops. Related: What Is Aperture...
is designed to behave like a window as light moves as straight as possible through its series of elements, the fisheye lens uses its elements like a funnel, bending a wide angle of light captured by the extremely curved outer element of the lens toward the film or sensor inside the camera...
a camera is a device that captures light and processes it into an image. it does this through a lens, which focuses the light onto a light-sensitive surface where a picture is formed. this could be film in traditional cameras or an electronic sensor in digital cameras. what are the key ...
